Area Vulnerability and Disparities in Therapy for Patients With Metastatic Renal Cell Carcinoma. JAMA Netw Open 2024; 7:e248747. [PMID: 38687479 PMCID: PMC11061765 DOI: 10.1001/jamanetworkopen.2024.8747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 02/28/2024] [Indexed: 05/02/2024] Open
Abstract
Importance Area-level measures of sociodemographic disadvantage may be associated with racial and ethnic disparities with respect to receipt of treatment for metastatic renal cell carcinoma (mRCC) but have not been investigated previously, to our knowledge. Objective To assess the association between area-level measures of social vulnerability and racial and ethnic disparities in the treatment of US Medicare beneficiaries with mRCC from 2015 through 2019. Design, Setting, and Participants This retrospective cohort study included Medicare beneficiaries older than 65 years who were diagnosed with mRCC from January 2015 through December 2019 and were enrolled in fee-for-service Medicare Parts A, B, and D from 1 year before through 1 year after presumed diagnosis or until death. Data were analyzed from November 22, 2022, through January 26, 2024. Exposures Five different county-level measures of disadvantage and 4 zip code-level measures of vulnerability or deprivation and segregation were used to dichotomize whether an individual resided in the most vulnerable quartile according to each metric. Patient-level factors included age, race and ethnicity, sex, diagnosis year, comorbidities, frailty, Medicare and Medicaid dual enrollment eligibility, and Medicare Part D low-income subsidy (LIS). Main Outcomes and Measures The main outcomes were receipt and type of systemic therapy (oral anticancer agent or immunotherapy from 2 months before to 1 year after diagnosis of mRCC) as a function of patient and area-level characteristics. Multivariable regression analyses were used to adjust for patient factors, and odds ratios (ORs) from logistic regression and relative risk ratios (RRRs) from multinomial logistic regression are reported. Results The sample included 15 407 patients (mean [SD] age, 75.6 [6.8] years), of whom 9360 (60.8%) were men; 6931 (45.0%), older than 75 years; 93 (0.6%), American Indian or Alaska Native; 257 (1.7%), Asian or Pacific Islander; 757 (4.9%), Hispanic; 1017 (6.6%), non-Hispanic Black; 12 966 (84.2%), non-Hispanic White; 121 (0.8%), other; and 196 (1.3%), unknown. Overall, 8317 patients (54.0%) received some type of systemic therapy. After adjusting for individual factors, no county or zip code-level measures of social vulnerability, deprivation, or segregation were associated with disparities in treatment. In contrast, patient-level factors, including female sex (OR, 0.78; 95% CI, 0.73-0.84) and LIS (OR, 0.48; 95% CI, 0.36-0.65), were associated with lack of treatment, with particularly limited access to immunotherapy for patients with LIS (RRR, 0.25; 95% CI, 0.14-0.43). Associations between individual-level factors and treatment in multivariable analysis were not mediated by the addition of area-level metrics. Disparities by race and ethnicity were consistently and only observed within the most vulnerable areas, as indicated by the top quartile of each vulnerability deprivation index. Conclusions and Relevance In this cohort study of older Medicare patients diagnosed with mRCC, individual-level demographics, including race and ethnicity, sex, and income, were associated with receipt of systemic therapy, whereas area-level measures were not. However, individual-level racial and ethnic disparities were largely limited to socially vulnerable areas, suggesting that efforts to improve racial and ethnic disparities may be most effective when targeted to socially vulnerable areas.

Trends in new and persistent opioid use in older adults with and without cancer. J Natl Cancer Inst 2024; 116:316-323. [PMID: 37802882 DOI: 10.1093/jnci/djad206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 09/11/2023] [Accepted: 09/26/2023] [Indexed: 10/08/2023] Open
Abstract
BACKGROUND The impact of ongoing efforts to decrease opioid use on patients with cancer remains undefined. Our objective was to determine trends in new and additional opioid use in patients with and without cancer. METHODS This retrospective cohort study used data from Surveillance, Epidemiology, and End Results program-Medicare for opioid-naive patients with solid tumor malignancies diagnosed from 2012 through 2017 and a random sample of patients without cancer. We identified 238 470 eligible patients with cancer and further focused on 4 clinical strata: patients without cancer, patients with metastatic cancer, patients with nonmetastatic cancer treated with surgery alone ("surgery alone"), and patients with nonmetastatic cancer treated with surgery plus chemotherapy or radiation therapy ("surgery+"). We identified new, early additional, and long-term additional opioid use and calculated the change in predicted probability of these outcomes from 2012 to 2017. RESULTS New opioid use was higher in patients with cancer (46.4%) than in those without (6.9%) (P < .001). From 2012 to 2017, the predicted probability of new opioid use was more stable in the cancer strata (relative declines: 0.1% surgery alone; 2.4% surgery+; 8.8% metastatic cancer), than in the noncancer stratum (20.0%) (P < .001 for each cancer to noncancer comparison). Early additional use declined among surgery patients (‒14.9% and ‒17.5% for surgery alone and surgery+, respectively) but was stable among patients with metastatic disease (‒2.8%, P = .50). CONCLUSIONS Opioid prescribing declined over time at a slower rate in patients with cancer than in patients without cancer. Our study suggests important but tempered effects of the changing opioid climate on patients with cancer.

Characteristics, healthcare utilization, and outcomes of patients with HER2-low breast cancer. Breast Cancer Res Treat 2024; 203:329-338. [PMID: 37875669 DOI: 10.1007/s10549-023-07142-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 09/25/2023] [Indexed: 10/26/2023]
Abstract
PURPOSE Treatment for HER2-low [defined as ImmunoHistoChemistry (IHC) 1 + or 2 + and negative/normal in Situ Hybridization (ISH)] breast cancer patients is rapidly evolving, yet we lack critical information about the HER2-low population. METHODS We conducted a retrospective cohort study of women aged 18 years or older diagnosed with breast cancer between 2010 and 2016 in North Carolina. Analyses were conducted for the overall cohort and a stage IV sub-cohort. We examined demographic and clinical characteristics, and characterized prevalence of HER2-low disease and healthcare utilization. We estimated adjusted rate ratios for the association between HER2 classifications and utilization outcomes, and hazard ratios for 3-year all cause mortality (stage IV only). RESULTS The overall and stage IV cohorts included 12,965 and 635 patients, respectively. HER2-low patients represented more than half of both cohorts (59% overall, 53% stage IV). HER2-low patients were more likely than IHC 0 patients to have hormone receptor (HR)-positive disease. In the stage IV cohort, HER2-low patients were more likely to be Black (26% vs. 16% IHC 0, p = 0.0159). In both cohorts, rates of hospitalizations were slightly higher among HER2-low patients. There were no survival differences between HER2-low and IHC 0 among stage IV patients. CONCLUSION New treatment options for HER2-low breast cancer may have potential for significant impact at the population level particularly for patients with stage IV disease. In light of racial differences between HER2-low and IHC 0 patients observed in our cohort, research- and practice-based efforts to ensure equitable adoption of new treatment guidelines for patients with HER2-low metastatic breast cancer will be essential.

Racial and Ethnic Variation in COVID-19 Vaccination Uptake Among Medicare Beneficiaries with Cancer History. J Racial Ethn Health Disparities 2023; 10:2354-2362. [PMID: 36149576 PMCID: PMC9510246 DOI: 10.1007/s40615-022-01415-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 09/13/2022] [Accepted: 09/14/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND The purpose of this study was to estimate COVID-19 vaccination rate among Medicare beneficiaries with cancer history and determine whether COVID-19 vaccine uptake is higher among non-Hispanic White beneficiaries compared with racially and ethnically minoritized beneficiaries. METHODS We used US representative, cross-sectional data from the Medicare Current Beneficiary Survey COVID-19 Winter 2021 Rapid Response Community Supplement Survey. A total of 1,863 respondents with self-reported cancer history (other than skin cancer) were included. The outcome was self-reported receipt of at least one coronavirus vaccine dose since vaccines became available. The key independent variable of interest was self-reported race and ethnicity. We applied sample weights to account for the survey design and provide population estimates to 9.6 million beneficiaries with cancer history. Weighted descriptive statistics and multivariable logistic regression analyses were conducted. RESULTS During the first 4 months of vaccine availability, 69.6% of beneficiaries received at least one vaccine dose of which 65.4% had two vaccine doses. A larger proportion of non-Hispanic White beneficiaries (71.9%) had at least one vaccine dose compared with non-Hispanic Black (60.4%) and Hispanic (57.4%) beneficiaries. An estimated 30.4% of beneficiaries were still unvaccinated, that represents approximately 2.9 million unvaccinated beneficiaries with cancer history. Hispanic beneficiaries were 42% (OR: 0.58; 95% CI: 0.33-0.99; p = .048) less likely to be vaccinated compared with non-Hispanic White beneficiaries. CONCLUSIONS Results indicate racial and ethnic differences in vaccine uptake among Medicare beneficiaries with cancer history. Effective strategies are needed to help increase vaccine confidence and uptake among adults with cancer history.

Relative Burden of Cancer and Noncancer Mortality Among Long-Term Survivors of Breast, Prostate, and Colorectal Cancer in the US. JAMA Netw Open 2023; 6:e2323115. [PMID: 37436746 PMCID: PMC10339147 DOI: 10.1001/jamanetworkopen.2023.23115] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 05/28/2023] [Indexed: 07/13/2023] Open
Abstract
Importance Improvements in cancer outcomes have led to a need to better understand long-term oncologic and nononcologic outcomes and quantify cancer-specific vs noncancer-specific mortality risks among long-term survivors. Objective To assess absolute and relative cancer-specific vs noncancer-specific mortality rates among long-term survivors of cancer, as well as associated risk factors. Design, Setting, and Participants This cohort study included 627 702 patients in the Surveillance, Epidemiology, and End Results cancer registry with breast, prostate, or colorectal cancer who received a diagnosis between January 1, 2003, and December 31, 2014, who received definitive treatment for localized disease and who were alive 5 years after their initial diagnosis (ie, long-term survivors of cancer). Statistical analysis was conducted from November 2022 to January 2023. Main Outcomes and Measures Survival time ratios (TRs) were calculated using accelerated failure time models, and the primary outcome of interest examined was death from index cancer vs alternative (nonindex cancer) mortality across breast, prostate, colon, and rectal cancer cohorts. Secondary outcomes included subgroup mortality in cancer-specific risk groups, categorized based on prognostic factors, and proportion of deaths due to cancer-specific vs noncancer-specific causes. Independent variables included age, sex, race and ethnicity, income, residence, stage, grade, estrogen receptor status, progesterone receptor status, prostate-specific antigen level, and Gleason score. Follow-up ended in 2019. Results The study included 627 702 patients (mean [SD] age, 61.1 [12.3] years; 434 848 women [69.3%]): 364 230 with breast cancer, 118 839 with prostate cancer, and 144 633 with colorectal cancer who survived 5 years or more from an initial diagnosis of early-stage cancer. Factors associated with shorter median cancer-specific survival included stage III disease for breast cancer (TR, 0.54; 95% CI, 0.53-0.55) and colorectal cancer (colon: TR, 0.60; 95% CI, 0.58-0.62; rectal: TR, 0.71; 95% CI, 0.69-0.74), as well as a Gleason score of 8 or higher for prostate cancer (TR, 0.61; 95% CI, 0.58-0.63). For all cancer cohorts, patients at low risk had at least a 3-fold higher noncancer-specific mortality compared with cancer-specific mortality at 10 years of diagnosis. Patients at high risk had a higher cumulative incidence of cancer-specific mortality than noncancer-specific mortality in all cancer cohorts except prostate. Conclusions and Relevance This study is the first to date to examine competing oncologic and nononcologic risks focusing on long-term adult survivors of cancer. Knowledge of the relative risks facing long-term survivors may help provide pragmatic guidance to patients and clinicians regarding the importance of ongoing primary and oncologic-focused care.

Factors Associated With Receipt of Molecular Testing and its Impact on Time to Initial Systemic Therapy in Metastatic Non-Small Cell Lung Cancer. Clin Lung Cancer 2023; 24:305-312. [PMID: 37055337 DOI: 10.1016/j.cllc.2023.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 02/13/2023] [Accepted: 03/10/2023] [Indexed: 04/15/2023]
Abstract
BACKGROUND Despite recommendations for molecular testing irrespective of patient characteristics, differences exist in receipt of molecular testing for oncogenic drivers amongst metastatic non-small cell lung cancer (mNSCLC) patients. Exploration into these differences and their effects on treatment is needed to identify opportunities for improvement. PATIENTS AND METHODS We conducted a retrospective cohort study of adult patients diagnosed with mNSCLC between 2011 and 2018 using PCORnet's Rapid Cycle Research Project dataset (n = 3600). Log-binomial, Cox proportional hazards (PH), and time-varying Cox regression models were used to ascertain whether molecular testing was received, and time from diagnosis to molecular testing and/or initial systemic treatment in the context of patient age, sex, race/ethnicity, and multiple comorbidities status. RESULTS The majority of patients in this cohort were ≤ 65 years of age (median [25th, 75th]: 64 [57, 71]), male (54.3%), non-Hispanic white individuals (81.6%), with > 2 comorbidities in addition to mNSCLC (54.1%). About half the cohort received molecular testing (49.9%). Patients who received molecular testing had a 59% higher probability of initial systemic treatment than patients who were yet to receive testing. Multiple comorbidity status was positively associated with receipt of molecular testing (RR, 1.27; 95% CI 1.08, 1.49). CONCLUSION Receipt of molecular testing in academic centers was associated with earlier initiation of systemic treatment. This finding underscores the need to increase molecular testing rates amongst mNSCLC patients during a clinically relevant period. Further studies to validate these findings in community centers are warranted.

Abstract
Disparities in metastatic renal cell carcinoma (mRCC) outcomes persist in the era of oral anticancer agents (OAAs) and immunotherapies (IOs). We examined variation in the utilization of mRCC systemic therapies among US Medicare beneficiaries from 2015 to 2019. Logistic regression models evaluated the association between therapy receipt and demographic covariates including patient race, ethnicity, and sex. In total, 15 407 patients met study criteria. After multivariable adjustment, non-Hispanic Black race and ethnicity was associated with reduced IO (adjusted relative risk ratio [aRRR] = 0.76, 95% confidence interval [CI] = 0.61 to 0.95; P = .015) and OAA receipt (aRRR = 0.76, 95% CI = 0.64 to 0.90; P = .002) compared with non-Hispanic White race and ethnicity. Female sex was associated with reduced IO (aRRR = 0.73, 95% CI = 0.66 to 0.81; P < .001) and OAA receipt (aRRR = 0.74, 95% CI = 0.68 to 0.81; P < .001) compared with male sex. Thus, disparities by race, ethnicity, and sex were observed in mRCC systemic therapy utilization for Medicare beneficiaries from 2015 to 2019.

Clinician Perspectives on Managing Chronic Pain After Curative-Intent Cancer Treatment. JCO Oncol Pract 2023; 19:e484-e491. [PMID: 36595729 PMCID: PMC10530392 DOI: 10.1200/op.22.00410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 08/19/2022] [Accepted: 11/04/2022] [Indexed: 01/04/2023] Open
Abstract
PURPOSE Among cancer survivors who have completed curative-intent treatment, the high prevalence and adverse consequences of chronic pain are well documented. Yet, research on clinicians' experiences with and perspectives on managing chronic pain among cancer survivors is critically lacking. METHODS We conducted semistructured interviews with 17 clinicians (six oncology, three palliative care, and eight primary care) affiliated with an academic medical center. Interview questions addressed clinicians' experiences with and perspectives on managing chronic pain (with or without opioid therapy) during the transition from active treatment to survivorship. A multidisciplinary team conducted content analysis of interview transcripts to identify and refine themes related to current practices and challenges in managing chronic pain in this context. RESULTS Overall, clinicians perceived chronic pain to be relatively uncommon among cancer survivors. Identified challenges included a lack of clarity about which clinician (or clinicians) are best positioned to manage chronic pain among cancer survivors, and (relatedly) complexities introduced by long-term opioid management, with many clinicians describing this practice as outside their skill set. Additionally, although most clinicians recognized chronic pain as a biopsychosocial phenomenon, they described challenges with effectively managing psychosocial stressors, including difficulty accessing mental or behavioral health services for cancer survivors. CONCLUSION Discovered challenges highlight unmet needs related to cancer survivor-clinician communication about chronic pain and the absence of a chronic pain management home for cancer survivors, including those requiring long-term opioid therapy. Research evaluating routine pain monitoring and accessible, tailored models of multimodal pain care in survivorship may help to address these challenges.

End-of-Life Care for Patients With Metastatic Renal Cell Carcinoma in the Era of Oral Anticancer Therapy. JCO Oncol Pract 2023; 19:e213-e227. [PMID: 36413741 PMCID: PMC9970274 DOI: 10.1200/op.22.00401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 08/31/2022] [Accepted: 10/06/2022] [Indexed: 11/23/2022] Open
Abstract
PURPOSE New therapies including oral anticancer agents (OAAs) have improved outcomes for patients with metastatic renal cell carcinoma (mRCC). However, little is known about the quality of end-of-life (EOL) care and systemic therapy use at EOL in patients receiving OAAs or with mRCC. METHODS We retrospectively analyzed EOL care for decedents with mRCC in two parallel cohorts: (1) patients (RCC diagnosed 2004-2015) from the University of North Carolina's Cancer Information and Population Health Resource (CIPHR) and (2) patients (diagnosed 2007-2015) from SEER-Medicare. We assessed hospice use in the last 30 days of life and existing measures of poor-quality EOL care: systemic therapy, hospital admission, intensive care unit admission, and > 1 ED visit in the last 30 days of life; hospice initiation in the last 3 days of life; and in-hospital death. Associations between OAA use, patient and provider characteristics, and EOL care were examined using multivariable logistic regression. RESULTS We identified 410 decedents in the CIPHR cohort (53.4% received OAA) and 1,508 in SEER-Medicare (43.5% received OAA). Prior OAA use was associated with increased systemic therapy in the last 30 days of life in both cohorts (CIPHR: 26.5% v 11.0%; P < .001; SEER-Medicare: 23.4% v 11.7%; P < .001), increased in-hospital death in CIPHR, and increased hospice in the last 30 days in SEER-Medicare. Older patients were less likely to receive systemic therapy or be admitted in the last 30 days or die in hospital. CONCLUSION Patients with mRCC who received OAAs and younger patients experienced more aggressive EOL care, suggesting opportunities to optimize high-quality EOL care in these groups.

Abstract
OBJECTIVE To examine real-world adherence to oral anticancer agents (OAAs) and its association with outcomes among Medicare beneficiaries with metastatic renal cell carcinoma (mRCC). METHODS SEER-Medicare retrospective cohort study of patients with metastatic renal cell carcinoma (mRCC) who received an OAA between 2007 and 2015. We examined A) adherence and B) overall and disease-specific 2-year survival landmarked at 3 months after OAA initiation. Adherence was assessed by calculating the proportion of days covered (PDC) within 3 months of OAA initiation, with adherent use being defined as PDC > 80%. RESULTS A total of 905 patients met study criteria, of whom 445 patients (49.2%) were categorized as adherent to initial OAA treatment. Adjusting for clinical and demographic factors revealed decreased odds of adherence associated with living within an impoverished neighborhood (OR 0.49, CI 0.0.33 - 0.74) and out-of-pocket costs > $200 (OR 0.68, CI 0.47-.98). Adherence was associated with improved 2-year survival in univariate analysis (logrank test, P = .01) and a non-significant trend toward an association with decreased all-cause (HR 0.87, CI 0.72 - 1.05) and RCC-specific survival (HR 0.84, CI 0.69 - 1.03) in multivariable analysis. CONCLUSION Local poverty levels and high out-of-pocket costs are associated with poor initial adherence to OAA therapy in Medicare beneficiaries with mRCC, which in turn, suggests a trend toward poor overall and disease-specific survival. Efforts to improve outcomes in the broader mRCC population should incorporate OAA adherence and economic factors.

Patient- And Provider-Level Predictors of Survival Among Patients With Metastatic Renal Cell Carcinoma Initiating Oral Anticancer Agents. Clin Genitourin Cancer 2022; 20:e396-e405. [PMID: 35595633 PMCID: PMC9529768 DOI: 10.1016/j.clgc.2022.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 04/14/2022] [Accepted: 04/18/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE In an era of rapid expansion of FDA approvals for oral anticancer agents (OAAs), it is important to understand the factors associated with survival among real-world populations, which include groups not well-represented in pivotal clinical trials of OAAs, such as the elderly, racial minorities, and medically complex patients. Our objective was to evaluate patient- and provider-level characteristics' associations with mortality among a multi-payer cohort of metastatic renal cell carcinoma (mRCC) patients who initiated OAAs. METHODS This retrospective cohort study was conducted using data from the North Carolina state cancer registry linked to multi-payer claims data for the years 2004 to 2015. Provider data were obtained from North Carolina Health Professions Data System and the National Plan & Provider Enumeration System. Included patients were individuals with mRCC who initiated an OAA and survived ≥90 days after beginning treatment. We estimated hazard ratios (HR) and corresponding 95% confidence limits (CL) using Cox hazard models for associations between patient demographics, patient clinical characteristics, provider-level factors, and 2-year all-cause mortality. RESULTS The cohort included 207 patients with mRCC who received OAAs. In multivariable models, clinical variables such as frailty (HR: 1.36, 95% CL: 1.11-1.67) and de novo metastatic diagnosis (HR: 2.63, 95%CL: 1.67-4.16) were associated with higher all-cause mortality. Additionally, patients solely on Medicare had higher adjusted all-cause mortality compared with patients with any private insurance (HR: 2.35, 95% CL: 1.32-4.18). No provider-level covariates investigated were associated with all-cause mortality. CONCLUSIONS Within a real-world population of mRCC patients taking OAAs, survival differed based on patient characteristics. In an era of rapid expansion of FDA approvals for OAAs, these real-world data underscore the continued importance of access to high-quality care, particularly for medically complex patients with limited resources.

Abstract
BACKGROUND Kidney cancer is the fastest-growing cancer diagnosis in the developed world. About 16% of new cases are stage IV, which has a low five-year survival rate. Many patients with metastatic renal cell carcinoma (mRCC) are older and may have mild cognitive impairment or dementia (MCI/D). Given prior reports of patients with dementia initiating less cancer therapy and the importance of oral anticancer agents (OAAs) in mRCC treatment, we investigated the prevalence of preexisting MCI/D in patients with mRCC and their OAA use. METHODS SEER-Medicare patients were analyzed who were ≥65 years, diagnosed with mRCC between 2007 and 2015, and had Medicare part D coverage. Patterns and predictors of (a) OAA utilization within the 12 months following mRCC diagnosis and (b) adherence (percent of days covered [PDC] ≥ 80%) during the first 90 days following treatment initiation were assessed. RESULTS Of the 2792 eligible patients, 268 had preexisting MCI/D, and 907 initiated OAA treatment within 12 months of mRCC diagnosis. Patients with preexisting MCI/D were less likely to begin an OAA than those without MCI/D (fully-adjusted HR 0.53, 95% CI 0.38-0.76). Among OAA initiators, a preexisting MCI/D diagnosis did not alter the likelihood that a person would be adherent (adjusted RR 0.84, 95% CI 0.55-1.28). CONCLUSIONS Patients with preexisting MCI/D were half as likely to start an OAA during the year following mRCC diagnosis than patients without comorbid MCI/D. The 90-day adherence of OAA initiators was not significantly different between those with and without preexisting MCI/D. In light of this, clinicians should assess mRCC patients for cognitive impairment and take steps to optimize OAA utilization by those with MCI/D.

Evaluation of mild cognitive impairment and dementia in patients with metastatic renal cell carcinoma. J Geriatr Oncol 2022; 13:635-643. [PMID: 34996724 PMCID: PMC9232862 DOI: 10.1016/j.jgo.2021.12.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 12/07/2021] [Accepted: 12/14/2021] [Indexed: 01/07/2023]
Abstract
BACKGROUND Dementia and cancer are both more common in adults as they age. As new cancer treatments become more popular, it is important to consider how these treatments might affect older patients. This study evaluates metastatic renal cell carcinoma (mRCC) as a risk factor for older adults developing mild cognitive impairment or dementia (MCI/D) and the impact of mRCC-directed therapies on the development of MCI/D. METHODS We identified patients diagnosed with mRCC in a Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset from 2007 to 2015 and matched them to non-cancer controls. Exclusion criteria included age < 65 years at mRCC diagnosis and diagnosis of MCI/D within the year preceding mRCC diagnosis. The main outcome was time to incident MCI/D within one year of mRCC diagnosis for cases or cohort entry for non-cancer controls. Cox proportional hazards models were used to measure associations between mRCC and incident MCI/D as well as associations of oral anticancer agent (OAA) use with MCI/D development within the mRCC group. RESULTS Patients with mRCC (n = 2533) were matched to non-cancer controls (n = 7027). mRCC (hazard ratio [HR] 8.52, p < .001), being older (HR 1.05 per 1-year age increase, p < .001), and identifying as Black (HR 1.92, p = .047) were predictive of developing MCI/D. In addition, neither those initiating treatment with OAAs nor those who underwent nephrectomy were more likely to develop MCI/D. CONCLUSIONS Patients with mRCC were more likely to develop MCI/D than those without mRCC. The medical and surgical therapies evaluated were not associated with increased incidence of MCI/D. The increased incidence of MCI/D in older adults with mRCC may be the result of the pathology itself or risk factors common to the two disease processes.

Patient, provider, and hospital factors associated with oral anti-neoplastic agent initiation and adherence in older patients with metastatic renal cell carcinoma. J Geriatr Oncol 2022; 13:614-623. [PMID: 35125336 PMCID: PMC9232903 DOI: 10.1016/j.jgo.2022.01.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 12/16/2021] [Accepted: 01/13/2022] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Oral anti-neoplastic agents (OAAs) for metastatic renal cell carcinoma (mRCC) are associated with increased cancer-specific survival. However, racial disparities in survival persist and older adults have the lowest rates of cancer-specific survival. Research from other cancers demonstrates specialty access is associated with high-quality cancer care, but older adults receive cancer treatment less often than younger adults. We therefore examined whether patient, provider, and hospital characteristics were associated with OAA initiation, adherence, and cancer-specific survival after initiation and whether race, ethnicity, and/or age was associated with an increased likelihood of seeing a medical oncologist for diagnosis of mRCC. PATIENTS AND METHODS We used Surveillance, Epidemiology, and End Results (SEER)Medicare data to identify patients ≥65 years of age who were diagnosed with mRCC from 2007 to 2015 and enrolled in Medicare Part D. Insurance claims were used to identify receipt of OAAs within twelve months of metastatic diagnosis, calculate proportion of days covered, and to identify the primary cancer provider and hospital. We examined provider and hospital characteristics associated with OAA initiation, adherence, and all-cause mortality after OAA initiation. RESULTS We identified 2792 patients who met inclusion criteria. Increased OAA initiation was associated with access to a medical oncologist. Patients were less likely to begin OAA treatment if their primary oncologic provider was a urologist (hazard ratio [HR] 0.62; 95% confidence interval [CI] 0.49-0.77). Provider/hospital characteristics were not associated with differences in OAA adherence or mortality. Patients who started sorafenib (odds ratio [OR] 0.50; 95% CI 0.29-0.86), were older (aged >81 OR 0.56; 95% CI 0.34-0.92), and those living in high poverty ZIP codes (OR 0.48; 95% CI 0.29-0.80) were less likely to adhere to OAA treatment. Furthermore, provider characteristics did not account for differences in mortality once an OAA was initiated. Last, only age > 81 years was statistically and clinically associated with a decreased relative risk of seeing a medical oncologist (risk ratio [RR] 0.87; CI 0.82-0.92). CONCLUSION Provider/hospital factors, specifically, being seen by a medical oncologist for mRCC diagnosis, are associated with OAA initiation. Older patients were less likely to see a medical oncologist; however, race and/or ethnicity was not associated with differences in seeing a medical oncologist. Patient factors are more critical to OAA adherence and mortality after OAA initiation than provider/hospital factors.

Opioid Prescribing and Use Among Cancer Survivors: A Mapping Review of Observational and Intervention Studies. J Pain Symptom Manage 2022; 63:e397-e417. [PMID: 34748896 DOI: 10.1016/j.jpainsymman.2021.10.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 10/22/2021] [Accepted: 10/23/2021] [Indexed: 12/12/2022]
Abstract
CONTEXT Recent years show a sharp increase in research on opioid use among cancer survivors, but evidence syntheses are lacking, leaving knowledge gaps. Corresponding research needs are unclear. OBJECTIVES To provide an evidence synthesis. METHODS We searched PubMed and Embase, identifying articles related to cancer, and opioid prescribing/use published through September 2020. We screened resulting titles/abstracts. Relevant studies underwent full-text review. Inclusion criteria were quantitative examination of and primary focus on opioid prescribing or use, and explicit inclusion of cancer survivors. Exclusion criteria included end-of-life opioid use and opioid use as a secondary or downstream outcome (for intervention studies). We extracted information on the opioid-related outcome(s) examined (including definitions and terminology used), study design, and methods. RESULTS Research returned 16,591 articles; 296 were included. Only 22 of 296 studies evaluated an intervention. There were 105 studies evaluating outcomes indicative of potentially high-risk, nonrecommended, or avoidable opioid use, e.g., continuous use-described as chronic use, prolonged use, and persistent use (n = 17); use after completion of curative-intent treatment-described as chronic opioid use, long-term opioid use, persistent opioid use, prolonged opioid use, continued opioid use, late opioid use, post-treatment opioid use (n = 27); use of opioids concurrent with other potentially high-risk medications (n = 13), and opioid misuse (n = 14). CONCLUSIONS We found lack of consistency in the measurement of and terms used to describe similar opioid use outcomes, and a lack of interventional research targeting well-documented patterns of potentially nonrecommended, potentially avoidable, or potentially high-risk opioid prescribing or use.

Low-touch, team-based care for co-morbidity management in cancer patients: the ONE TEAM randomized controlled trial. BMC FAMILY PRACTICE 2021; 22:234. [PMID: 34794388 PMCID: PMC8600877 DOI: 10.1186/s12875-021-01569-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 10/19/2021] [Indexed: 01/22/2023]
Abstract
Background As treatments for cancer have improved, more people are surviving cancer. However, compared to people without a history of cancer, cancer survivors are more likely to die of cardiovascular disease (CVD). Increased risk for CVD-related mortality among cancer survivors is partially due to lack of medication adherence and problems that exist in care coordination between cancer specialists, primary care physicians, and cardiologists. Methods/Design The Onco-primary care networking to support TEAM-based care (ONE TEAM) study is an 18-month cluster-randomized controlled trial with clustering at the primary care clinic level. ONE TEAM compares the provision of the iGuide intervention to patients and primary care providers versus an education-only control. For phase 1, at the patient level, the intervention includes video vignettes and a live webinar; provider-level interventions include electronic health records-based communication and case-based webinars. Participants will be enrolled from across North Carolina one of their first visits with a cancer specialist (e.g., surgeon, radiation or medical oncologist). We use a sequential multiple assignment randomized trial (SMART) design. Outcomes (measured at the patient level) will include Healthcare Effectiveness Data and Information Set (HEDIS) quality measures of management of three CVD comorbidities using laboratory testing (glycated hemoglobin [A1c], lipid profile) and blood pressure measurements; (2) medication adherence assessed pharmacy refill data using Proportion of Days Covered (PDC); and (3) patient-provider communication (Patient-Centered Communication in Cancer Care, PCC-Ca-36). Primary care clinics in the intervention arm will be considered non-responders if 90% or more of their participating patients do not meet the modified HEDIS quality metrics at the 6-month measurement, assessed once the first enrollee from each practice reaches the 12-month mark. Non-responders will be re-randomized to either continue to receive the iGuide 1 intervention, or to receive the iGuide 2 intervention, which includes tailored videos for participants and specialist consults with primary care providers. Discussion As the population of cancer survivors grows, ONE TEAM will contribute to closing the CVD outcomes gap among cancer survivors by optimizing and integrating cancer care and primary care teams. ONE TEAM is designed so that it will be possible for others to emulate and implement at scale. Trial registration This study (NCT04258813) was registered in clinicaltrals.gov on February 6, 2020.

Real-World Utilization of Oral Anticancer Agents and Related Costs in Older Adults with Metastatic Renal Cell Carcinoma in the United States. KIDNEY CANCER 2021; 5:115-127. [PMID: 34632169 PMCID: PMC8474520 DOI: 10.3233/kca-210119] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 05/21/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND Substantial racial and socioeconomic disparities in metastatic RCC (mRCC) have persisted following the introduction of targeted oral anticancer agents (OAAs). The relationship between patient characteristics and OAA access and costs that may underlie persistent disparities in mRCC outcomes have not been examined in a nationally representative patient population. METHODS Retrospective SEER-Medicare analysis of patients diagnosed with mRCC between 2007-2015 over age 65 with Medicare part D prescription drug coverage. Associations between patient characteristics, OAA receipt, and associated costs were analyzed in the 12 months following mRCC diagnosis and adjusted to 2015 dollars. RESULTS 2,792 patients met inclusion criteria, of which 32.4%received an OAA. Most patients received sunitinib (57%) or pazopanib (28%) as their first oral therapy. Receipt of OAA did not differ by race/ethnicity or socioeconomic indicators. Patients of advanced age (> 80 years), unmarried patients, and patients residing in the Southern US were less likely to receive OAAs. The mean inflation-adjusted 30-day cost to Medicare of a patient's first OAA prescription nearly doubled from $3864 in 2007 to $7482 in 2015, while patient out-of-pocket cost decreased from $2409 to $1477. CONCLUSION Race, ethnicity, and socioeconomic status were not associated with decreased OAA receipt in patients with mRCC; however, residing in the Southern United States was, as was marital status. Surprisingly, the cost to Medicare of an initial OAA prescription nearly doubled from 2007 to 2015, while patient out-of-pocket costs decreased substantially. Shifts in OAA costs may have significant economic implications in the era of personalized medicine.

Abstract
IMPORTANCE Understanding interactions among health service, sociodemographic, clinical, and genomic factors in breast cancer disparities research has been limited by a disconnect between health services and basic biological approaches. OBJECTIVE To describe the first linkage of Surveillance, Epidemiology, and End Results (SEER)-Medicare data to physical tumor samples and to investigate the interaction among screening detection, socioeconomic status, tumor stage, tumor biology, and breast cancer outcomes within a single context. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study used tumor specimen blocks from a subset of women aged 66 to 75 years with newly diagnosed nonmetastatic, estrogen receptor-positive invasive breast cancer from January 1, 1993, to December 31, 2007. Specimens were obtained from the Iowa and Hawaii SEER Residual Tissue Repositories (RTRs) and linked with Medicare claims data and survival assessed through December 31, 2015. Data were analyzed from August 1, 2018, to July 25, 2021. EXPOSURES Screening- vs symptom-based detection of tumors was assessed using validated claims-based algorithms. Demographic factors and zip code-based educational attainment and poverty socioeconomic characteristics were obtained via SEER. MAIN OUTCOMES AND MEASURES Molecular subtyping and exploratory genomic analyses were completed using the NanoString Breast Cancer 360 gene expression panel containing the 50-gene signature classifier. Factors associated with overall and breast cancer-specific (BCS) survival were analyzed using Cox proportional hazards regression models combining sociodemographic, clinical, and genomic data. RESULTS SEER-Medicare data were available for 3522 women (mean [SD] age, 70.9 [2.6] years; 3049 [86.6%] White), of whom 1555 (44.2%) were diagnosed by screening mammogram. In the SEER-Medicare cohort, factors associated with increased BCS mortality included symptomatic detection (hazard ratio [HR], 1.49 [95% CI, 1.16-1.91]), advanced disease stage (HR for stage III, 2.33 [95% CI, 1.41-3.85]), and high-grade disease (HR, 1.85 [95% CI, 1.46-2.34]). The molecular cohort of 130 cases with luminal A/B cancer further revealed increased all-cause mortality associated with genomic upregulation of transforming growth factor β activation and p53 dysregulation (eg, p53 dysregulation: HR, 2.15 [95% CI, 1.20-3.86]) and decreased mortality associated with androgen receptor, macrophage, cytotoxicity, and Treg signaling (eg, androgen receptor signaling: HR, 0.23 [95% CI, 0.12-0.45]). Symptomatic detection (HR, 2.49 [95% CI, 1.19-5.20]) and zip codes with low levels of educational attainment (HR, 5.17 [95% CI, 2.12-12.60]) remained associated with mortality after adjusting for all clinical and demographic factors. CONCLUSIONS AND RELEVANCE Linkage of SEER-Medicare data to physical tumor specimens may elucidate associations among biology, health care access, and disparities in breast cancer outcomes. The findings of this study suggest that screening detection and socioeconomic status are associated with survival in patients with locally advanced, estrogen receptor-positive tumors, even after incorporating clinical and genomic factors.

Abstract
IMPORTANCE The clinical decisions that arise from prostate magnetic resonance imaging (MRI) and genomic testing in patients with prostate cancer are not well understood. OBJECTIVE To evaluate the association between regional uptake of prostate MRI and genomic testing and observation vs treatment for prostate cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study of commercial insurance claims for prostate MRI and genomic testing included 65 530 patients 40 to 89 years of age newly diagnosed with prostate cancer from July 1, 2012, through June 30, 2019. EXPOSURES Patient- and regional-level use of prostate MRI and genomic testing. MAIN OUTCOMES AND MEASURES Observation vs definitive treatment for prostate cancer. Patient-level analyses examined the association between receipt of testing or residing in a hospital referral region (HRR) that adopted testing and observation. In regional-level analyses, the dependent variable was the change in the proportion of patients observed for prostate cancer at the HRR level between 2 periods: July 1, 2012, to June 30, 2014, and July 1, 2017, to June 20, 2019. The independent study variables included HRR-level changes in the proportion of men undergoing prostate MRI and genomic testing between these periods, and the models were adjusted for contextual factors associated with prostate cancer care and socioeconomic status. RESULTS This study identified 65 530 patients, including 27 679 in the early period (mean [SD] age, 58.0 [5.9] years) and 37 851 in the late period (mean [SD] age, 59.0 [5.7] years). Use of prostate MRI increased significantly from 7.2% (95% CI, 6.9%-7.5%) to 16.7% (95% CI, 16.3%-17.1%) from the early to late period. Use of genomic testing increased significantly from 1.3% (95% CI, 1.1%-1.4%) to 12.7% (95% CI, 12.3%-13.0%) from the early to late period. Compared with the lowest, the highest HRR quartiles of prostate MRI and genomic testing uptake were associated with an adjusted 4.1% (SE, 1.1%; P < .001) and 2.5% (SE, 1.1%; P = .03) absolute increase in the proportion of patients receiving observation, respectively. CONCLUSIONS AND RELEVANCE In this cohort study, uptake of prostate MRI and genomic testing was associated with increased use of initial observation vs treatment for prostate cancer. Marked geographic variation supports the need for further patient-level research to optimize the dissemination and outcome of testing.

Provider- and patient-level predictors of oral anticancer agent initiation and adherence in patients with metastatic renal cell carcinoma. Cancer Med 2021; 10:6653-6665. [PMID: 34480518 PMCID: PMC8495289 DOI: 10.1002/cam4.4201] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 07/28/2021] [Accepted: 07/29/2021] [Indexed: 01/25/2023] Open
Abstract
Background Improving oral anticancer agent (OAA) initiation and adherence is the important quality‐of‐care issues, particularly since one fourth of anticancer agents being developed will be administered orally. Our objective was to identify provider‐ and patient‐level characteristics associated with OAA initiation and adherence among individuals with metastatic renal cell carcinoma (mRCC). Methods We used state cancer registry data linked to multi‐payer claims data to identify patients with mRCC diagnosed in 2004–2015. Provider data were obtained from North Carolina Health Professions Data System and the National Plan & Provider Enumeration System. We estimated risk ratios (RRs) and corresponding 95% confidence limits (CLs) using modified Poisson regression to evaluate factors associated with OAA initiation and adherence. Results Among the 207 (out of 687) patients who initiated an OAA following mRCC diagnosis and survived 90 days, median proportion of days covered was 0.91. Patients with a modal provider specializing in hematology/medical oncology were much more likely to initiate OAAs than those seen by other specialties. Additionally, patients with a female provider were more likely to initiate OAAs than those with a male provider. Compared to patients treated by providers practicing in both urban and rural areas, patients with providers practicing solely in urban areas were more likely to initiate OAAs, after controlling for patient‐level factors (RR = 1.37; 95% CL: 1.09–1.73). Medicare patients were less likely to be adherent than those with private insurance (RR = 0.61; 95% CL: 0.42–0.87). Conclusions Our results suggest that provider‐ and patient‐level factors influence OAA initiation in patients with mRCC but only insurance type was associated with adherence.

Abstract
PURPOSE Availability of targeted oral anticancer agents (OAAs) has transformed care for patients with metastatic renal cell carcinoma (mRCC). Our objective was to identify patterns and predictors of OAA use within 12 months after mRCC was detected to understand real-world adoption of OAAs. METHODS We used a novel, North Carolina cancer registry-linked multipayer claims data resource to examine patterns of use of five oral therapies among patients with mRCC diagnosed in 2006-2015, with claims through 2016. Patients were required to have 12 months of continuous enrollment before metastatic index date. Log-Poisson models estimated unadjusted and adjusted risk ratios (RRs) for associations between patient characteristics and OAA use. In sensitivity analyses, we used a competing risk framework to estimate adjusted risk differences in OAA use. RESULTS Our population-based study of 713 patients demonstrated low (37%) OAA use during the first year after metastatic index date among both publicly and privately insured patients, with shifting patterns of use consistent with regulatory approvals over time. Compared with patients age 18-49 years, patients age 70-74 years were half likely to use OAAs (95% confidence limit [CL], 0.34 to 0.78) and patients age 80+ years were 71% less likely to use OAAs (95% CL, 0.17 to 0.50). Patients with two comorbidities (RR, 0.73; 95% CL, 0.55 to 0.98) and those with 3+ comorbidities (RR, 0.68; 95% CL, 0.50 to 0.91) were less likely to receive OAA than those without comorbidities. Patients with higher frailty also had lower OAA utilization (RR, 0.67; 95% CL, 0.52 to 0.85). CONCLUSION These findings suggest a need to better understand the system-level and provider-level drivers of OAA underuse, as well as OAA adherence and associated survival.

Abstract
Background No population-based studies have examined chronic opioid use among cancer survivors who are diverse with respect to diagnosis, age group, and insurance status. Methods We conducted a retrospective cohort study using North Carolina cancer registry data linked with claims from public and private insurance (2006-2016). We included adults with nonmetastatic cancer who had no prior chronic opioid use (n = 38 366). We used modified Poisson regression to assess the adjusted relative risk of chronic opioid use in survivorship (>90-day continuous supply of opioids in the 13-24 months following diagnosis) associated with patient characteristics. Results Only 3.0% of cancer survivors in our cohort used opioids chronically in survivorship. Predictors included younger age (adjusted risk ratio [aRR] 50-59 vs 60-69 = 1.23, 95% confidence interval [CI] = 1.05 to 1.43), baseline depression (aRR = 1.22, 95% CI = 1.06 to 1.41) or substance use (aRR = 1.43, 95% CI = 1.15 to 1.78) and Medicaid (aRR vs private = 1.93, 95% CI = 1.56 to 2.40). Survivors who used opioids intermittently (vs not at all) before diagnosis were twice as likely to use opioids chronically in survivorship (aRR = 2.62, 95% CI = 2.28 to 3.02). Those who used opioids chronically (vs intermittently or not at all) during active treatment had a nearly 17-fold increased likelihood of chronic use in survivorship (aRR = 16.65, 95% CI = 14.30 to 19.40). Conclusions Younger and low-income survivors, those with baseline depression or substance use, and those who require chronic opioid therapy during treatment are at increased risk for chronic opioid use in survivorship. Our findings point to opportunities to improve assessment of psychosocial histories and to engage patients in shared decision-making around long-term pain management, when chronic opioid therapy is required during treatment.

Abstract
IMPORTANCE Adequate representation of demographic subgroups in premarketing and postmarketing clinical studies is necessary for understanding the safety and efficacy associated with novel cancer therapeutics. OBJECTIVE To characterize and compare the reporting of demographic data and the representation of individuals by sex, age, and race in premarketing and postmarketing studies used by the Food and Drug Administration (FDA) to evaluate novel cancer therapeutics. DESIGN, SETTING, AND PARTICIPANTS In this cross-sectional study, premarketing and postmarketing studies for novel cancer therapeutics approved by the FDA from 2012 through 2016 were identified. Study demographic information was abstracted from publicly available sources, and US cancer population demographic data was abstracted from US Cancer Statistics. Analyses were conducted from February 25 through September 21, 2020. MAIN OUTCOMES AND MEASURES The percentages of trials reporting sex, age, and race/ethnicity were calculated, and participation to prevalence ratios (PPRs) were calculated by dividing the percentage of study participants in each demographic group by the percentage of the US cancer population in each group. PPRs were constructed for premarketing and postmarketing studies and by cancer type. Underrepresentation was defined as PPR less than 0.8. RESULTS From 2012 through 2016, the FDA approved 45 cancer therapeutics. The study sample included 77 premarketing studies and 56 postmarketing studies. Postmarketing studies, compared with premarketing studies, were less likely to report patient sex (42 studies reporting [75.0%] vs 77 studies reporting [100%]; P < .001) and race (27 studies reporting [48.2%] vs 62 studies reporting [80.5%]; P < .001). Women were adequately represented in premarketing studies (mean [SD] PPR, 0.91; 95% CI, 0.90-0.91) and postmarketing studies (mean PPR, 1.00; 95% CI, 1.00-1.01). Although older adults and Black patients were underrepresented in premarketing studies (older adults: mean PPR, 0.73; 95% CI, 0.72-0.74; Black patients: mean PPR, 0.32; 95% CI, 0.31-0.32), these groups continued to be underrepresented in postmarketing studies (older adults: mean PPR, 0.75; 95% CI, 0.75-0.76; Black patients: mean PPR, 0.21; 95% CI, 0.21-0.21). CONCLUSIONS AND RELEVANCE This study found that older adults and Black patients were underrepresented in postmarketing studies of novel cancer therapeutics to a similar degree that they were underrepresented in premarketing studies. These findings suggest that postmarketing studies are not associated with improvements to gaps in demographic representation present at the time of FDA approval.

Treatment at Integrated Centers Might Bridge the Academic-Community Survival Gap in Patients With Metastatic Non-Small Cell Carcinoma of the Lung. Clin Lung Cancer 2021; 22:e646-e653. [PMID: 33582071 DOI: 10.1016/j.cllc.2020.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 12/14/2020] [Accepted: 12/29/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is responsible for the most cancer-related deaths in the United States. A better understanding of treatment-related disparities and ways to address them are important to improving survival for patients with metastatic NSCLC. MATERIALS AND METHODS We performed a retrospective analysis using the National Cancer Database. Included in this analysis were 107,116 patients with metastatic NSCLC who were treated at academic centers (AC), community-based centers (CC), and integrated centers (IC) between 2004 and 2015. The primary end point was overall survival, with comparisons of AC, CC, and IC. RESULTS The survival disparity between AC and CC continued to grow over the study period, from a 5.7% difference in 2-year survival to a 7.5% difference. Treatment at IC was initially associated with survival similar to CC (hazard ratio [HR], 0.93), however, later in the study period treatment at IC improved (HR, 0.74) outpacing the improvement in survival in CC (HR, 0.82) but not to the same degree as the improvement in AC (HR, 0.64). The improvement in survival at IC was noted predominantly in patients with adenocarcinoma (HR, 0.72; P < .001) but not in squamous-cell carcinoma (HR, 0.89; P value not significant). CONCLUSION Treatment of metastatic NSCLC at IC was associated with improved survival during our study period compared with treatment at CC. This appeared to be histology-dependent, suggesting a treatment-related improvement in survival because over this period newer therapies were preferentially available for adenocarcinoma. Integrating care across treatment facilities might be one way to bridge the growing gap in survival between AC and CC.

Rapid rise in the cost of targeted cancer therapies for Medicare patients with solid tumors from 2006 to 2015. J Geriatr Oncol 2020; 12:375-380. [PMID: 33250425 DOI: 10.1016/j.jgo.2020.11.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 09/24/2020] [Accepted: 11/20/2020] [Indexed: 12/31/2022]
Abstract
BACKGROUND Inflation-adjusted cancer costs in the United States have increased 40% in the last decade, leading to increasing financial burden on both payers and patients. Patients under 65 show substantial increases in utilization of expensive targeted therapy anticancer agents; however, patients aged 65+ account for the majority of new malignancies. Utilization and cost trends for these emerging agents have not been examined in detail in the Medicare population. PATIENTS AND METHODS Retrospective prevalent cohort analysis of patients 65+ with any stage of invasive lung, breast, colorectal, or prostate cancer, receiving systemic therapy drawn from the United States Medicare 5% fee-for-service sample claims (2005-2015). Yearly trends in utilization and associated costs were modeled with adjustment for inflation, demographics, and comorbidities. RESULTS Among Medicare beneficiaries with fee-for-service and Part D enrollment who were receiving some type of systemic anticancer therapy, there were 9230 patients with colorectal, 32,738 patients with breast, and 16,278 patients with lung cancers identified from 2006 to 2015, and 19,295 patients with prostate cancer from 2009 to 2015. The share of cancer costs to Medicare attributable to targeted therapies, increased dramatically for prostate cancer (1.7% to 19.4%), lung cancer (6.7% to 19.4%), colorectal cancer (11.7% to 22.2%), and breast cancer (15.8% to 25.5%). Although the proportion of patients receiving targeted therapies remained stable, mean per-patient cancer costs increased dramatically from 2006 to 2015 for patients with lung or prostate cancer receiving targeted therapy and for patients with breast cancer receiving non-hormonal targeted therapies. Targeted agents for these cancers showed substantial inflation-adjusted price growth over this time period.

Real-world systemic therapy utilization in Medicare patients with locally advanced or metastatic urothelial carcinoma diagnosed between 2008 and 2012. J Geriatr Oncol 2020; 12:298-304. [PMID: 32912737 DOI: 10.1016/j.jgo.2020.08.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 04/18/2020] [Accepted: 08/18/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Treatment of advanced urothelial carcinoma (UC) remains a challenging clinical entity occurring predominantly in older patients with limited treatment options. However, real-world treatment patterns, differential cancer center access, and association with outcomes is lacking in nationally representative clinical practice and will provide context for emerging therapies. MATERIALS AND METHODS We used SEER-Medicare data to identify patients with locally advanced or metastatic UC of the bladder or upper urinary tract diagnosed between 2008 and 2012. We characterized utilization systemic therapy, including first- and second-line chemotherapy. Patients receiving neoadjuvant chemotherapy were excluded; results were stratified by academic versus non-academic setting. RESULTS 3569 patients met study criteria; 48% received some form of chemotherapy within 2 years of diagnosis. Of these, one-third subsequently received second-line chemotherapy. The majority received a regimen including ≥2 agents. Gemcitabine alone or in combination with platinum was the most common first- and second-line treatment. Similar patterns of first- and second-line chemotherapy were observed between patients treated in academic and non-academic centers. Sensitivity analyses of trial-similar patients demonstrated increased utilization (69%). Receipt of platinum doublet as 1st line therapy was less likely in older patients and those with renal disease, and more likely for grade IV disease. CONCLUSIONS Roughly half of all Medicare patients with locally advanced/metastatic UC receive systemic therapy regardless of access to academic cancer centers and despite poor oncologic outcomes. Cytotoxic, gemcitabine-based doublet chemotherapy remains the most common treatment. A substantial population of older patients exists for whom alternative, non-cytotoxic, treatment options may be of benefit.

Abstract
BACKGROUND This study examined whether associations between 21-gene recurrence score (RS) genomic testing and lower costs among patients with early-stage, estrogen receptor-positive breast cancer are observable in real-world data from the Medicare population. METHODS A retrospective cohort study was conducted using SEER-Medicare data for a nationally representative sample of Medicare beneficiaries diagnosed from 2005 through 2011. The main outcomes were associations between RS testing and overall and chemotherapy-specific costs. The primary analysis was restricted to patients aged 66 to 75 years. RESULTS The primary analysis comprised 30,058 patients. Mean costs 1 year after diagnosis were $35,940 [SD, $28,894] overall, $51,127 [33,386] for clinically high-risk disease, $33,225 [$27,711] for intermediate-risk disease, and $26,695 [$19,532] for low-risk disease. Chemotherapy-specific costs followed similar trends. In multivariable analyses, RS testing was associated with significantly lower costs among high-risk patients in terms of both relative costs (cost ratio, 0.88; 99% CI, 0.82-0.94) and absolute costs ($6,606; 99% CI, $39,223-$9,290). Higher costs among low-risk and intermediate-risk patients were mainly caused by higher noncancer costs. In sensitivity analyses that included all patients aged ≥66 years (N=64,996), associations between RS testing and costs among high-risk patients were similar but less pronounced because of lower overall use of chemotherapy. CONCLUSIONS RS testing was associated with lower overall and chemotherapy-related costs in patients with high-risk disease, consistent with lower chemotherapy use among these patients. Higher overall costs for patients with intermediate-risk and low-risk disease were driven largely by non-treatment-related costs.

Abstract
Cancer precision medicine depends on high-quality tumor biomarker tests (TBTs) for treatment selection. TBT reimbursement within the United States in the current regulatory environment is not tied to premarket evidence of clinical utility, resulting in a vicious cycle wherein low-level evidence of utility leads to poor reimbursement, thereby impeding investment in developing new, clinically valuable TBTs supported by high-level evidence. Rational, value-based TBT pricing presents many practical challenges. Precise one-to-one mapping of reimbursement to cost savings or cost effectiveness is precluded by an absence of formal cost-effectiveness analyses for many emerging TBTs, and for more established TBTs, it has become clear that such analyses may yield wildly variable, subjective estimates. To address these challenges, we propose a system of tiered reimbursement that rewards development of high-quality TBTs within specific use contexts, supported by strong evidence of analytic validity and clinical utility. We propose three use contexts of TBTs, each defined by its influence on treatment decisions relative to the current standard of care-Opt-Out, Opt-In, and the use of appropriate, alternative, effective therapies (Opt-Alt). By ensuring minimum levels of reimbursement, this system provides a return on investment to encourage and support the research and development needed to generate high levels of evidence for claims of clinical utility for TBTs by using a robust, objective, and value-based system. We believe our proposed evaluation system will serve as a practical starting point to raise the bar for TBT quality and utility, which has the potential to redirect health care dollars from futile or ineffective treatment to investment in the development of high-quality TBTs needed for safe and effective precision cancer care.

Abstract
PURPOSE Efforts to curb the rising costs of cancer care while improving quality include alternative payment models (APMs), which offer incentives to reduce avoidable spending and provide high-quality and cost-efficient care. The impact of proposed APMs has not been quantified in real-world practice. In this study, we evaluated ASCO's Patient-Centered Oncology Payment (PCOP) model in existing fee-for-service (FFS) Medicare beneficiaries to understand the magnitude of potential cost savings. MATERIALS AND METHODS SEER-Medicare data were used to identify women with advanced ovarian cancer diagnosed between 2000 and 2012 who either (1) underwent primary debulking surgery followed by chemotherapy or (2) received neoadjuvant chemotherapy followed by surgery. Medicare payments in each cohort were used to compare FFS and PCOP and to estimate the potential for cost savings across health care services received, including outpatient emergency department visits, hospitalizations, and imaging. RESULTS Three thousand seven hundred seventy-seven primary debulking surgery and 866 neoadjuvant chemotherapy patients were included in the study, with mean total costs of $75,433 and $95,138 in 2016 US$, respectively Most costs were related to chemotherapy or hospitalization. Additional PCOP-related payments would be offset if hospitalizations could be reduced by 11.6% or imaging claims by 88%. CONCLUSION APMs have the potential to reduce costs of current FFS reimbursement via either a large reduction in imaging or a modest reduction in hospitalizations during treatment of ovarian cancer. PCOP is a reasonable payment structure for oncologists if the additional payments can provide the necessary resources to invest in improved coordination of care.

Extent of surgery for low-risk thyroid cancer in the elderly: Equipoise in survival but not in short-term outcomes. Surgery 2019; 166:895-900.

Abstract
BACKGROUND Total thyroidectomy is more common than lobectomy for low-risk papillary thyroid cancer, despite equipoise in survival. Because postoperative morbidity increases with age, we aimed to investigate how the extent of thyroidectomy affects short-term outcomes among older patients. METHODS Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified patients aged ≥66 years who were treated between 1996 and 2011 for papillary thyroid cancer with tumors ≤2 cm in diameter. We used multivariable logistic regression to evaluate the effect of extent of surgery on complications, emergency-department visits, and unplanned readmissions. RESULTS Among 3,341 selected patients, 77.3% were female, mean age was 72.9 years, and tumors averaged 0.8 cm in diameter. A total of 67.6% of patients underwent total thyroidectomy, and 32.4% underwent lobectomy. Total thyroidectomy was associated with complications (odds ratio = 1.99) and readmissions (odds ratio = 1.59; both P < 0.01). Complications were higher in female patients (odds ratio = 1.34), black patients (versus white patients, odds ratio = 1.65), and those with ≥2 comorbidities (vs 0, odds ratio = 1.43; all P < 0.01). Black patients and those with ≥2 comorbidities had more emergency-department visits (odds ratio = 1.50 and 1.92, respectively) and readmissions (odds ratio = 2.19 and 2.29, respectively; all P < 0.01). CONCLUSION Total thyroidectomy for older adults with low-risk papillary thyroid cancer may lead to potentially avoidable complications and readmissions, particularly for black and female patients. In many cases, lobectomy may be a safer and less costly alternative.

Abstract
OBJECTIVE Recombinant human thyroid-stimulating hormone (rhTSH) has been approved for diagnostic (1998) and therapeutic (2008) indications in conjunction with radioactive iodine (RAI) administration post-thyroidectomy. Potential benefits of rhTSH, including avoidance of hypothyroidism side effects and shorter, less costly hospital stays, have not been assessed at the population level within the United States. In this study we quantify utilization, outcomes, and associated costs of rhTSH within the nationally representative Surveillance, Epidemiology, and End Results (SEER)-Medicare patient population. METHODS We conducted a retrospective analysis of beneficiaries aged >65 years diagnosed within the SEER-Medicare data with differentiated thyroid cancer. Endpoints examined included ( 1) rhTSH utilization in the 2 years post-thyroidectomy (patients diagnosed 1996-2011 [utilization cohort]) and ( 2) comparison of resource utilization and costs as a function of rhTSH receipt in the 30 days prior to and 1 year following therapeutic RAI administration (patients diagnosed 2008-2011 [resource use cohort]). All costs were adjusted to reflect 2013 dollars. RESULTS A total of 6,482 patients met inclusion criteria, of which, 1,363 (21.0%) received rhTSH. Receipt varied by region and was higher in the South (18%), Northeast (28%), and West (44%) compared to the Midwest (10%), and lower in census tracts in the bottom quartile of high school education rates (odds ratio 0.68, 95% confidence interval [CI] 0.55-0.83). rhTSH receipt was not associated with patient sex, age, comorbidities, or stage. Post-therapeutic RAI, 1,444 patients were assessed for resource utilization (2008-2011). The average cost of rhTSH was $905 per patient, with $2,483 being spent on average among patients who received rhTSH in association with therapeutic RAI. rhTSH receipt was not significantly associated with total inpatient days or number of outpatient and emergency department visits. Multivariable analyses showed similar overall costs among patients who did versus did not receive rhTSH (cost ratio [CR] 0.96, 95% CI 0.86-1.09), partially due to increased mean outpatient costs ($5,213 vs. $4,190) being offset by lower inpatient costs ($3,493 vs. $6,143). Overall costs were significantly higher in multivariable analyses among patients with distant metastatic disease (CR 1.92, 95% CI 1.58-2.32) and multiple comorbidities (CR 2.15, 95% CI 1.83-2.53). CONCLUSION rhTSH recipients had higher outpatient, lower inpatient, and similar total Medicare payments as those not receiving rhTSH in conjunction with RAI, lending support to the use of rhTSH as a cost-neutral treatment option from the payer perspective. ABBREVIATIONS CI = confidence interval; CMS = Centers for Medicare & Medicaid Services; CR = cost ratio; HCPCS = Healthcare Common Procedure Coding System; IQR = interquartile range; mCi = millicurie; OR = odds ratio; PET = positron emission tomography; RAI = radioactive iodine; rhTSH = recombinant human thyroid-stimulating hormone; RR = risk ratio; SEER = Surveillance, Epidemiology, and End Results.

Abstract
INTRODUCTION Advanced imaging can inform prognosis and may be a mechanism to de-escalate unnecessary end-of-life care in patients with cancer. Associations between greater use of advanced imaging and less-aggressive end-of-life care in real-world practice has not been examined. METHODS We conducted a retrospective analysis of SEER-Medicare data on patients who died from breast, lung, colorectal, or prostate cancer between 2002 and 2007. Hospital referral region (HRR)-level use of computerized tomography (CT), magnetic resonance imaging, and positron emission tomography was categorized by tertile of imaging use and correlated with hospice enrollment overall and late hospice enrollment using multivariable logistic regression. RESULTS A total of 55,058 patients met study criteria. Hospice use ranged from 50.8% (colorectal cancer) to 62.1% (prostate cancer). In multivariable analyses, hospital referral regions (HRRs) with high rates of CT imaging were associated with lower odds of hospice enrollment (odds ratio, 0.80; 95% CI, 0.70-0.90) and late enrollment among those who did enroll (odds ratio, 1.49; 95% CI, 1.26-1.76). HRRs with the highest rates of CT use were predominantly located in the Midwest and Northeast and associated with higher percentage population of black patients (14.5 vs 5.6%), greater comorbidity (28.4 vs 23.7%), metropolitan residence (93.9 vs 78.5%), and less than high school education (26.4 vs 19.3%). CONCLUSION In this population-based retrospective study, we did not observe evidence that overall and timely hospice are associated with higher rates of imaging near the end of life. An observed association between higher rates of imaging, particularly CT, may be explained in part by HRR-level differences in practice patterns and patient demographic characteristics. Further research is warranted to explore the ability of oncologic imaging to appropriately de-escalate care.

Abstract
PURPOSE We sought to determine whether physician-level characteristics were associated with 21-gene recurrence score (RS) genomic testing to evaluate recurrence risk and benefit of adjuvant chemotherapy in patients with estrogen receptor-positive, node-negative breast cancer. METHODS Retrospective cohort study of a nationally representative sample of Medicare beneficiaries using Surveillance, Epidemiology, and End Results program-Medicare data linked with the American Medical Association physician master file. The main outcome was receipt of genomic testing within 1 year of diagnosis as a function of physician-level factors. RESULTS A total of 24,463 patients met the study criteria; they received care from 3172 surgeons and 2475 medical oncologists. Of 4124 tests ordered, 70% were ordered by a medical oncologist and 16% by a surgeon. In multivariable regression models, multiple variables were associated with receipt of testing, including having a medical oncologist (odds ratio [OR] 2.77; 95% CI 2.00-3.82), a surgeon specializing in surgical oncology (OR 1.20; 95% CI 1.09-1.31), and a female medical oncologist (OR 1.10; 95% CI 1.02-1.20). Having a medical oncologist with 5 or more years in practice was associated with lower odds of testing (OR 0.83; 95% CI 0.76-0.92). Surgical procedures performed at academic centers were associated with higher odds of testing (OR 1.11; 95% CI 1.02-1.20). CONCLUSIONS Although most RS testing was ordered by medical oncologists, physicians in other specialties ordered roughly one-third of the tests. Physician characteristics, including gender and time in practice, were associated with receiving testing, creating opportunities for targeting interventions to help patients receive optimal care.

Abstract
Abstract
Background: Oncotype DX (ODX) genomic testing to evaluate recurrence risk and benefit of adjuvant chemotherapy in patients with ER-positive, node-negative breast cancers was approved for Medicare reimbursement in 2006. We previously examined patient-level factors associated with utilization of ODX testing from 2005-2009 in the SEER-Medicare population; ODX testing occurred most frequently in patients with ER+, node negative disease, with 80% of all tests occurring in patients aged 66-75. In our current study, we examined potential provider factors associated with patient-level ODX testing from 2008 to 2012.
Methods: Using a retrospective cohort design, we identified all individuals who had a SEER diagnosis of breast cancer from 2008-2011 and were enrolled in fee-for-service Medicare parts A and B for one year before and one year after diagnosis. We limited our analysis to individuals who had surgical resection of their breast tumor within 4 months of diagnosis and had a breast tumor which was ER+, invasive, and non-metastatic to capture the eligible patient population. Using Medicare claims data linked with the AMA physician dataset (which includes AMA members and non-members), we identified physician characteristics of the primary breast surgeon and medical oncologist including specialty, gender, years in practice, case volume, utilization of chemotherapy, and whether they serve rural populations. For patients with an ODX test, we used the identification on the claim to link to the performing provider. We examined the associations between provider characteristics and patient receipt of ODX testing using unadjusted and adjusted logistic regression models. Adjusted models included patient demographic and clinical characteristics.
Results: We identified 24,463 eligible breast cancer patients who received their care from 3172 primary surgeons and 2475 medical oncologists. Of 4124 ODX tests ordered for patients in the study, 70% were ordered by the assigned medical oncologist and 16% were ordered by the breast surgeon. In multivariable regression models, multiple physician characteristics were associated with receipt of ODX testing including having an assigned medical oncologist (OR 2.77, 95% CI 2.00-3.82), having a surgeon with a specialty of surgical oncology (OR 1.20, 95% CI 1.09-1.31), having a female medical oncologist (OR 1.10 95% CI 1.02-1.20). Having a medical oncologist with ≥5 years in practice was associated with lower odds of testing (OR 0.83 95% CI 0.76-0.92). Breast surgery performed at an academic hospital was associated with higher odds of ODX testing (OR 1.11 95% CI 1.02-1.20).
Conclusion: The majority of ODX testing for indicated breast cancer patients is ordered by medical oncologists, though surgeons and physicians of other specialties also order the tests in practice. Physician characteristics including gender and time in practice appear to affect a patient's likelihood of receiving ODX testing, creating opportunities for targeting interventions to help women with breast cancer receive optimal care.

Trends in hospital-physician integration in medical oncology. THE AMERICAN JOURNAL OF MANAGED CARE 2017; 23:624-627. [PMID: 29087634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/07/2023]
Abstract
OBJECTIVES Hospitals have rapidly acquired medical oncology practices in recent years. Experts disagree as to whether these trends are related to oncology-specific market factors or reflect a general trend of hospital-physician integration. The objective of this study was to compare the prevalence, geographic variation, and trends in physicians billing from hospital outpatient departments in medical oncology with other specialties. STUDY DESIGN Retrospective analysis of Medicare claims data for 2012 and 2013. METHODS We calculated the proportion of physicians and practitioners in the 15 highest-volume specialties who billed the majority of evaluation and management visits from hospital outpatient departments in each year, nationally and by state. RESULTS We included 338,998 and 352,321 providers in 2012 and 2013, respectively, of whom 9715 and 9969 were medical oncologists. Among the 15 specialties examined, medical oncology had the highest proportion of hospital outpatient department billing in 2012 and 2013 (35.0% and 38.3%, respectively). Medical oncology also experienced the greatest absolute change (3.3%) between the years, followed by thoracic surgery (2.4%) and cardiology (2.0%). There was marked state-level variation, with the proportion of medical oncologists based in hospital outpatient departments ranging from 0% in Nevada to 100% in Idaho. CONCLUSIONS Hospital-physician integration has been more pronounced in medical oncology than in other high-volume specialties and is increasing at a faster rate. Policy makers should take these findings into consideration, particularly with respect to recent proposals that may continue to fuel these trends.

Abstract
PURPOSE Patients who undergo surgery for papillary thyroid cancer with only a limited lymph node examination are thought to be at risk for potentially harboring occult disease. However, this risk has not been objectively quantified and may have implications for subsequent management and surveillance. METHODS Data from the National Cancer Database (1998 to 2012) were used to characterize the distribution of nodal positivity of adult patients diagnosed with localized ≥ 1-cm papillary thyroid cancer who underwent thyroidectomy with one or more lymph nodes (LNs) examined. A β-binomial distribution was used to estimate the probability of occult nodal disease as a function of total number of LNs examined and pathologic tumor stage. RESULTS A total of 78,724 patients met study criteria; 38,653 patients had node-positive disease. The probability of falsely identifying a patient as node negative was estimated to be 53% for patients with a single node examined and decreased to less than 10% when more than six LNs were examined. To rule out occult nodal disease with 90% confidence, six, nine, and 18 nodes would need to be examined for patients with T1b, T2, and T3 disease, respectively. Sensitivity analyses limited to patients likely undergoing prophylactic central neck dissection resulted in three, four, and eight nodes needed to provide comparable adequacy of LN evaluation. CONCLUSION To our knowledge, our study provides the first empirically based estimates of occult nodal disease risk in patients after surgery for papillary thyroid cancer as a function of primary tumor stage and number of LNs examined. Our estimates provide an objective guideline for evaluating adequacy of LN yield for surgeons and pathologists in the treatment of papillary thyroid cancer, and especially intermediate-risk disease, for which use of adjuvant radioactive iodine and surveillance intensity are not currently standardized.

Knowledge of pathologically versus clinically negative lymph nodes is associated with reduced use of radioactive iodine post-thyroidectomy for low-risk papillary thyroid cancer. Endocrine 2016; 52:579-86.

Abstract
Cervical lymph node metastases are common in papillary thyroid cancer (PTC). Clinically negative lymph nodes confer uncertainty about true lymph node status, potentially prompting empiric postoperative radioactive iodine (RAI) administration even in low-risk patients. We examined the association of clinically (cN0) versus pathologically negative (pN0) lymph nodes with utilization of RAI for low-risk PTC. Using the National Cancer Database 1998-2011, adults with PTC who underwent total thyroidectomy for Stage I/II tumors 1-4 cm were evaluated for receipt of RAI based on cN0 versus pN0 status. Cut-point analysis was conducted to determine the number of pN0 nodes associated with the greatest decrease in the odds of receipt of RAI. Survival models and multivariate analyses predicting RAI use were conducted separately for all patients and patients <45 years. 64,980 patients met study criteria; 39,778 (61.2 %) were cN0 versus 25,202 (38.8 %) pN0. Patients with pN0 nodes were more likely to have negative surgical margins and multifocal disease (all p < 0.001). The mean negative nodes reported in surgical pathology specimens was 4; ≥5 pathologically negative lymph nodes provided the best cut-point associated with reduced RAI administration (OR 0.91, CI 0.85-0.97). After multivariable adjustment, pN0 patients with ≥5 nodes examined were less likely to receive RAI compared to cN0 patients across all ages (OR 0.89, p < 0.001) and for patients aged <45 years (0R 0.86, p = 0.001). Patients with <5 pN0 nodes did not differ in RAI use compared to cN0 controls. Unadjusted survival was improved for pN0 versus cN0 patients across all ages (p < 0.001), but not for patients <45 years (p = 0.11); adjusted survival for all ages did not differ (p = 0.13). Pathological confirmation of negative lymph nodes in patients with PTC appears to influence the decision to administer postoperative RAI if ≥5 negative lymph nodes are removed. It is possible that fewer excised lymph nodes may be viewed by clinicians as incidentally resected and thus may suboptimally represent the true nodal status of the central neck. Further research is warranted to determine if there is an optimal number of lymph nodes that should be resected to standardize pathological diagnosis.

Abstract
Oncotype DX testing (ODX), a tumor gene expression test, may improve breast cancer care, however, communicating results remains challenging. We identified patient-centered communication strategies/gaps for discussing ODX results. We applied a patient-centered communication framework to analyze qualitative interviews with oncologists about how they communicate about ODX with patients, using template analysis in Atlas.ti. Overall, providers discussed four patient-centered communication domains: exchanging information, assessing uncertainty, making decisions and cross-cutting themes. Providers did not report discussing emotional aspects of managing uncertainty, assessing decision-making preferences, and evaluating decisions. A patient-centered approach may be a model for communicating about tumor gene expression tests.

Abstract
IMPORTANCE Guidelines recommend consideration of chemotherapy for most patients with early-stage, estrogen receptor-positive, invasive breast cancer in the absence of additional prognostic information. The 21-gene recurrence score (RS) assay has been shown in limited academic settings to reduce physician recommendations for adjuvant chemotherapy. Associations between the adoption of the assay and receipt of chemotherapy in the general population have not been examined. OBJECTIVE To examine whether adoption of the RS assay in a nationally representative sample of patients with early-stage breast cancer was associated with use of chemotherapy. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study of Medicare beneficiaries who received a diagnosis of incident breast cancer between 2005 and 2009 using Surveillance, Epidemiology, and End Results data set with linked Medicare claims. MAIN OUTCOMES AND MEASURES Receipt of chemotherapy within 12 months after diagnosis. RESULTS A total of 44,044 patients had low-risk (24.0%), intermediate-risk (51.3%), or high-risk disease (24.6%, lymph node positive) as defined by National Comprehensive Cancer Network (NCCN) guidelines and met the study criteria. We observed no overall association between receipt of the RS assay and chemotherapy (odds ratio [OR], 1.03 [99% CI, 0.88-1.19]). In multivariable analysis, there was a significant interaction between NCCN risk and use of the RS assay, with assay use associated with lower chemotherapy use in high-risk patients (OR, 0.36 [99% CI, 0.26-0.50]) and greater chemotherapy use in low-risk patients (OR, 3.71 [99% CI, 2.30-5.98]), compared with no receipt of the assay (P=.006 for the overall interaction). Results were similar in prespecified subgroup analyses of patients 70 years and younger, with the exception of a shift toward lower chemotherapy use during 2008 (OR, 0.90 [99% CI, 0.77-.1.05]; P=.09) and 2009 (OR, 0.81 [99% CI, 0.66-0.99]; P=.007). In unadjusted analyses, overall chemotherapy use decreased over time in patients 70 years or younger with high-risk disease and those receiving the assay. CONCLUSIONS AND RELEVANCE The impact of the adoption of the RS assay on receipt of chemotherapy was strongly population dependent and was associated with relatively lower chemotherapy use in groups with high-risk disease and relatively higher chemotherapy use in patients with low-risk disease. Overall use of chemotherapy decreased during the study period in patients who were most likely to receive chemotherapy.

Abstract
PURPOSE Oncotype DX (ODX) is a tumor gene-profiling test that aids in adjuvant chemotherapy decision-making. ODX has the potential to improve quality of care; however, if not equally accessible across racial groups, disparities in cancer care quality may persist or worsen. We examined racial disparities in ODX testing uptake. METHODS We used data from the Carolina Breast Cancer Study, phase III, a longitudinal, population-based study of 2,998 North Carolina women who received a diagnosis of breast cancer between 2008 and 2014. Our primary analysis used modified Poisson regression to determine the association between race and whether ODX testing was ordered among two strata: node-negative and node-positive breast cancer. RESULTS A total of 1,468 women with estrogen receptor-positive, human epidermal growth factor receptor-2-negative, stage I or II breast cancer met inclusion criteria. Black patients had higher-grade and larger tumors, more comorbidities, younger age at diagnosis, and lower socioeconomic status than non-black women. Overall, 42% of women had ODX test results in their pathology reports. Compared with those who did not receive ODX testing, women who received ODX testing tended to be younger and have medium tumor size and grade. Our regression analyses indicated no racial disparities in ODX uptake among node-negative patients. However, racial differences were detected among node-positive patients, with black patients being 46% less likely to receive ODX testing than non-black women (adjusted relative risk, 0.54; 95% CI, 0.35 to 0.84; P = .006). CONCLUSION We did not find racial disparities in ODX testing for node-negative patients for whom ODX testing is guideline recommended and widely covered by insurers. However, our findings suggest that a newer, non-guideline-concordant application of ODX testing for node-positive breast cancer was accessed less by black women than by non-black women, reflecting more guideline concordant care among black women.

Abstract
Treatment-associated neutropenia continues to represent the most common dose-limiting toxicity of cancer chemotherapy. It often leads to fever and infection, prompting hospitalization and occasionally resulting in serious morbidity, and even mortality, despite modern broad-spectrum antibiotic treatment and supportive care. Neutropenia and its complications may also lead to chemotherapy dose reductions, treatment delays, or early treatment termination, compromising disease control and the potential for cure. NCCN Clinical Practice Guidelines in Oncology recommend administration of primary prophylaxis with a myeloid growth factor in patients receiving regimens associated with a high risk for febrile neutropenia, and consideration of prophylaxis in patients receiving lower-risk regimens who have other risk factors that might place them at higher risk for febrile neutropenia. Although these agents have been shown to be effective and safe in numerous randomized controlled trials, they are expensive and contribute significantly to increasing health care costs. Regulatory agencies and guideline organizations do not currently address the issue of cost. However, with the relentless increase in health care use and current efforts to reform health care, it has become increasingly important to assess both the cost and the net benefit of interventions related to an episode of care in order to compare the overall value of therapeutic options. This article defines and discusses the intersection of quality, costs, and value in the context of prophylactic myeloid growth factor use in patients with cancer receiving myelosuppressive chemotherapy.

Resource Use in the Last Year of Life Among Patients Who Died With Versus of Prostate Cancer. Clin Genitourin Cancer 2015; 14:28-37.e2.

Abstract
UNLABELLED We conducted a retrospective analysis of Surveillance, Epidemiology, and End Results-Medicare data of men with prostate cancer. Among 34,727 patients, those who died of their prostate cancer had more hospice and outpatient use, less inpatient and intensive care unit use, and lower overall costs. Efforts to shift care toward the outpatient setting might provide more efficient and judicious care for patients during the end of life. BACKGROUND Prostate cancer poses a significant financial burden in the United States. However, most men with prostate cancer will die from noncancer causes. Concerns about increased resource utilization at the end of life have not been appropriately examined in this context. MATERIALS AND METHODS We conducted a retrospective analysis of Surveillance, Epidemiology, and End Results-Medicare data of men who were diagnosed with and died of, as opposed to with, prostate cancer between 2000 and 2007. Within these 2 populations, we compared changes in the use of medical interventions, hospice, and overall health care costs to Medicare in the last year of life. RESULTS Among 34,727 patients, those who died of prostate cancer had lower costs ($43,572 vs. $45,830; P < .001), largely because of lower mean inpatient costs ($20,769 vs. $29,851) and fewer hospitalizations (1.8 vs. 2.1), inpatient days (12.2 vs. 15.7), intensive care unit (ICU) days (1.4 vs. 3.4), and skilled nursing facility days (11.7 vs. 14.7; P < .001 for all). Outpatient and hospice costs were significantly greater among patients who died of prostate cancer, as was use of chemotherapy and androgen deprivation therapy. Patients who died of prostate cancer had approximately 12% lower costs than patients who died from other causes in adjusted analyses (fold-change, 0.88; 95% confidence interval [CI], 0.85-0.92). The single strongest predictor of increased costs at the end of life was receipt of multiple invasive procedures (fold increase in costs, 2.39; 95% CI, 2.22-2.58). CONCLUSION Patients who died of prostate cancer rather than from other causes had more hospice and outpatient use, less inpatient and ICU use, and lower overall costs. Efforts to shift care toward outpatient settings might provide more efficient and judicious care for patients during the end of life.

Abstract
BACKGROUND In recent years, palliative treatment of prostate cancer metastases has been characterized by the use of more complex radiation treatment, despite a lack of evidence demonstrating a clinical benefit of these technologies in the palliative setting. The impact of adoption of these technologies on the costs of palliative radiation treatment in patients with metastatic prostate cancer remains poorly understood in the general patient population. METHODS The study was a retrospective analysis of Surveillance, Epidemiology and End Results (SEER) Medicare data of men aged 66 and older who died from metastatic prostate cancer between 2000 and 2007 and received radiation therapy for bony metastases in the last year of life. Direct costs were obtained from Medicare carrier and outpatient facility payments for all radiation treatment claims and adjusted to 2008 dollars. RESULTS A total of 1705 men met study inclusion criteria. Total Medicare payments for radiation therapy for bony metastases in the last year of life increased by 44.4% from an average of $2,763 in 2000 to $3,989 in 2007, with the proportion of all payments accrued within hospital-based settings increasing from 48% to 57%. Complexity of radiation therapy techniques over the same period was characterized by use of less simple (30.1% to 23.3%) and more complex (59.9% versus 66.7%) radiation therapy. From 2000-2003 to 2004-2007, the use of shorter treatment courses (≤5 fractions) decreased from 22% to 14%, and the use of single fraction treatment courses decreased by half (6.3% to 2.9%; P≤.001). CONCLUSIONS Between 2000 and 2007, palliative radiation therapy for bony prostate cancer metastases was characterized by the use of more advanced treatment technologies and prolonged radiation treatment courses. Further research investigating barriers to cost-effective palliation is warranted.

Abstract
Purpose Cervical lymph node metastases are recognized as a prognostic indicator only in patients age 45 years or older with papillary thyroid cancer (PTC); patients younger than age 45 years are perceived to have low-risk disease. The current American Joint Committee on Cancer staging for PTC in patients younger than age 45 years does not include cervical lymph node metastases. Our objective was to test the hypothesis that the presence and number of cervical lymph node metastases have an adverse impact on overall survival (OS) in patients younger than age 45 years with PTC. Patients and Methods Adult patients younger than age 45 years undergoing surgery for stage I PTC (no distant metastases) were identified from the National Cancer Data Base (NCDB; 1998-2006) and from SEER 1988-2006 data. Multivariable models were used to examine the association of OS with the presence of lymph node metastases and number of metastatic nodes. Results In all, 47,902 patients in NCDB (11,740 with and 36,162 without nodal metastases) and 21,855 in the SEER database (5,188 with and 16,667 without nodal metastases) were included. After adjustment, OS was compromised for patients with nodal metastases compared with patients who did not have them (NCDB: hazard ratio (HR), 1.32; 95% CI, 1.04 to 1.67; P = .021; SEER: HR, 1.29; 95% CI, 1.08 to 1.56; P = .006). After adjustment, increasing number of metastatic lymph nodes was associated with decreasing OS up to six metastatic nodes (HR, 1.12; 95% CI, 1.01 to 1.25; P = .03), after which more positive nodes conferred no additional mortality risk (HR, 0.99; 95% CI, 0.99 to 1.05; P = .75). Conclusion Our results suggest that cervical lymph node metastases are associated with compromised survival in young patients, warranting consideration of revised American Joint Committee on Cancer staging. A change point of six or fewer metastatic lymph nodes seems to carry prognostic significance, thus advocating for rigorous preoperative screening for nodal metastases.
