Abstract
BACKGROUND Women with newly diagnosed cervical cancer are often treated with extensive, multimodal therapies that may include a combination of surgery, radiation, and chemotherapy. Little is known about the cost of treatment or how these costs are passed on to the patients. OBJECTIVE The objectives of this study were to examine the cost of care during the first year after a diagnosis of cervical cancer, to estimate the sources of the costs, and to explore the out-of-pocket costs. STUDY DESIGN We performed a study of women with commercial insurance who received a new diagnosis of cervical cancer, and whose cases were recorded in the MarketScan database from 2008 to 2016. Patients were categorized based on the primary treatment received being either surgery (hysterectomy with or without adjuvant radiation or chemotherapy) or radiation. The inflation-adjusted medical expenditures for a 12-month period beginning on the date of the first treatment were estimated. The payments were divided into the expenditures of inpatient care, outpatient care (including chemotherapy), and outpatient pharmacy costs. The out-of-pocket costs incurred by the patients in the form of copayments, coinsurance, and deductibles were estimated. RESULTS A total of 4495 patients, including 3014 (67%) who underwent surgery and 1481 (33%) who primarily underwent radiotherapy, were identified. The median total expenditure per patient during the first year after the diagnosis was $56,250 (interquartile range, $25,767-$107,532). The median total expenditure for patients with surgery as the primary treatment was $37,222 (interquartile range, $20,957-$75,555). The median total expenditure for patients treated primarily with radiotherapy was $101,266 (interquartile range, $63,155-$160,760). For patients treated primarily with surgery, inpatient services accounted for $15,145 (interquartile range, $0-$26,898), outpatient services accounted for $18,430 (interquartile range, $5354-$48,047), and outpatient pharmacy costs accounted for $628 (interquartile range, $141-$1847). The median cost for those women who did not require adjuvant therapy was $26,164 compared with $89,760 for women treated with adjuvant radiation. The median out-of-pocket costs for the cohort was $2253 (interquartile range, $1137-$3990) or 3.9% of the total costs. CONCLUSION The cost of care for women with newly diagnosed cervical cancer is substantial. Overall, patients are responsible for approximately 3.9% of the costs in the form of out-of-pocket expenditures.

Abstract
IMPORTANCE Although primary debulking surgery (PDS) is often considered the criterion standard for treatment of stage IV endometrial cancer, PDS is associated with significant morbidity and poor survival. Neoadjuvant chemotherapy (NACT) has been proposed as an alternative treatment strategy. OBJECTIVE To determine the use of and outcomes associated with NACT for women with stage IV endometrial cancer. DESIGN, SETTING, AND PARTICIPANTS This cohort study used the National Cancer Database to identify women with stage IV endometrial cancer treated from January 1, 2010, to December 31, 2015. The cohort was limited to women aged 70 years or younger with minimal comorbidity (comorbidity score = 0). Women were stratified based on receipt of NACT or PDS. A propensity score analysis with inverse probability weighting was performed to balance the clinical characteristics of the groups. Survival was examined using flexible parametric Royston-Parmer models to account for time-varying hazards associated with use of NACT. An intention-to-treat (ITT) analysis was performed, as was a per-protocol (PP) analysis that included only women who received treatment with both chemotherapy and surgery (in either sequence). Data were analyzed from March 15, 2018, to July 20, 2018. MAIN OUTCOMES AND MEASURES Use of NACT and overall survival. RESULTS Of a total of 4890 women (median age, 60 years [interquartile range, 54-65 years]) with stage IV endometrial cancer, NACT was used in 952 women (19.5%). Use of NACT increased from 106 of 661 women (16.0%; 95% CI, 13.2%-18.8%) in 2010 to 224 of 938 women (23.9%; 95% CI, 21.2%-26.6%) in 2015 (P < .001). In a multivariate model, more recent year of diagnosis (risk ratio [RR], 1.42; 95% CI, 1.21-1.79 for 2015 vs 2010), stage IVB disease (RR, 1.31; 95% CI, 1.03-1.67 for stage IVB vs IVA), and serous histology (RR, 1.38; 95% CI, 1.13-1.69 for serous vs endometrioid histology) were associated with use of NACT. In a propensity score-balanced cohort, use of NACT displayed a time-varying association with survival. In the ITT analysis, use of NACT was associated with decreased mortality for the first 3 months after diagnosis (hazard ratio [HR] at 2 months, 0.81; 95% CI, 0.66-0.99). After 4 months, the survival curves crossed, and receipt of NACT was associated with increased mortality (HR at 6 months, 1.23; 95% CI, 1.09-1.39). In the PP analysis, use of NACT was associated with decreased mortality for the first 8 months after diagnosis (HR at 6 months, 0.79; 95% CI, 0.63-0.98). After 9 months, the survival curves crossed, and receipt of NACT was associated with increased mortality (HR at 12 months, 1.22; 95% CI, 1.04-1.43). CONCLUSIONS AND RELEVANCE The results of this cohort study suggest that women treated with PDS are at increased risk of early death but have a more favorable long-term prognosis. In contrast, results suggest that women treated with NACT, particularly if they ultimately undergo surgery, may have superior survival in the short term. Based on these findings, NACT may be appropriate for select patients with advanced uterine serous carcinoma.

Abstract
Purpose To share better practice in establishing data monitoring committees (DMCs) for observational, retrospective safety studies with joint‐industry sponsorship. Methods A DMC model was created to monitor data from an observational, retrospective, post‐authorization safety study investigating risk of medullary thyroid cancer in patients treated with long‐acting glucagon‐like peptide‐1 receptor agonists (LA GLP‐1RAs) (NCT01511393). Sponsors reviewed regulatory guidelines, best practice and sponsors' standard operation procedures on DMCs. Discussions were held within the four‐member consortium, assessing applicability to observational, retrospective, real‐world studies. A DMC charter was drafted based on a sponsor‐proposed, adapted DMC model. Thereafter, a kick‐off meeting between sponsors and DMC members was held to receive DMC input and finalize the charter. Results Due to this study's observational, retrospective nature, assuring participant safety – central for traditional explanatory clinical trial models – was not applicable to our DMC model. The overall strategy and key indication for our real‐world model included preserving study integrity and credibility. Therefore, DMC member independence and their contribution of expert knowledge were essential. To ensure between‐sponsor data confidentiality, all study committees/corporations and sponsors, besides the DMC, received blinded data only (adapted to refer to data blinding that revealed the specific marketed LA GLP‐1RA/sponsor). Communication and blinding/unblinding of these data were facilitated by the contract research organization, which also provided crucial operational oversight. Conclusions To our knowledge, we have established the first DMC model for joint industry‐sponsored, observational, retrospective safety studies. This model could serve as a precedent for others performing similar post‐marketing, joint industry‐sponsored pharmacovigilance activities.

Abstract
BACKGROUND Recent data suggest that subcutaneous adiposity represents an independent prognostic marker in cancer. We aimed to determine whether subcutaneous adiposity estimated by the subcutaneous adiposity tissue index (SATI) was associated with mortality in esophageal cancer. METHODS We conducted a retrospective analysis of a prospectively enrolled cohort from 2009 to 2015 with esophageal cancer at two major cancer centers. CT scans for initial staging were used to quantify adiposity and skeletal muscle areas. Subjects were categorized as above or below median SATI using sex-specific values. Sarcopenia was defined using previously established skeletal muscle area cutoffs. Cox proportional hazards modeling was performed to determine associations between SATI and all-cause mortality. RESULTS Of the original 167 patients, 78 met inclusion criteria and had CT images available. Mean age was 67 years, 81.8% had adenocarcinoma, and 58.9% had stage 3 or 4 disease. Median follow-up time was 29.5 months. Overall 5-year survival was 38.9% [95% confidence interval (CI), 26.8-50.7]. Lower body mass index, higher Charlson comorbidity score, and more advanced stage were independently associated with low SATI. Patients with low SATI had increased mortality (unadjusted HR 2.23; 95% CI, 1.20-4.12), even when adjusted for sarcopenia or for percent weight loss. In a multivariable model including age, histology, stage, and receipt of curative surgery, the association between low SATI and mortality was attenuated (adjusted HR 1.64; 95% CI, 0.81-3.34). CONCLUSIONS Low subcutaneous adiposity as estimated by SATI may be associated with increased mortality in esophageal cancer. IMPACT Interventions to reduce loss of subcutaneous fat may improve survival in esophageal cancer.

Abstract
BACKGROUND Black women experience poorer survival compared with white women across all endometrial cancer stages and histologies. The incidence of endometrial cancer is 30% lower in black women compared with white women, yet mortality is 80% higher in black women. Differences in adherence to evidence-based guidelines have been proposed to be major contributors to this disparity. OBJECTIVES We examined whether adherence to evidence-based treatment recommendations for endometrial cancer could mitigate survival disparities between black and white women. STUDY DESIGN The National Cancer Database was used to identify women with endometrial cancer treated from 2004 through 2016. We established 5 evidence-based quality metrics based on review of primary literature and accepted guidelines: surgical treatment within 6 weeks of diagnosis (Q1), use of minimally invasive surgery (stage I-IIIC; Q2), pelvic nodal assessment (high-risk tumors; Q3), adjuvant radiation (high intermediate risk; Q4), and systemic chemotherapy (stage III-IV; Q5). The rates of 30 and 90 day mortality and 5 year survival were compared between black and white women. To determine the influence of quality on outcomes, we compared outcomes among perfectly adherent black and white women with stage I and III endometrial cancer. RESULTS We identified 310,208 women including 35,035 (11.3%) black women and 275,173 (88.3%) white women. Black women were less likely than white women to receive Q1 (65.8 vs 75.6%), Q2 (58.5 vs 72.9%), Q3 (71.3 vs 74.2%), and Q5 (72.7 vs 73.2%) (P < .05 for all). Adherence to each quality metrics was associated with improved survival. Among women with stage I disease, perfect adherence to the relative quality metrics was seen in 53.1% of white and 41.5% of black women. Among perfectly adherent stage I patients, outcomes in black women improved relative to unselected black women; however, they still experienced higher risk of 30 day (adjusted relative risk, 2.25; 95% confidence interval, 1.30-3.90), 90 day (adjusted relative risk, 1.84; 95% confidence interval, 1.23-2.76), and 5 year mortality (adjusted hazard ratio, 1.42; 95% confidence interval, 1.26-1.59) compared with similar white women. Among women with stage III tumors, perfect adherence to the relative quality metrics was seen in 56.6% of white and 44.1% of black women. Perfectly adherent black women with stage III disease had improved outcomes but remained at increased risk of 30 day (adjusted relative risk, 1.86; 95% confidence interval, 1.01-3.44) and 5 year mortality (adjusted hazard ratio, 1.35; 95% confidence interval, 1.22-1.50) compared with white women. CONCLUSION Black women are less likely than white women with endometrial cancer to receive evidence-based care. However, receipt of evidence-based care mitigates but does not eliminate racial disparities in outcomes and black women remain at greater risk of death from endometrial cancer.

Abstract
PURPOSE Among patients diagnosed with breast cancer (BC), women also living with HIV (WLWH) have worse survival than women without HIV. Chronic HIV infection may interfere with the effectiveness of BC treatment, contributing to this disparity. We attempted to determine the impact of HIV infection on response to neoadjuvant chemotherapy (NACT) among South African women with BC. METHODS We evaluated women from the South African Breast Cancer and HIV Outcomes cohort study who had stage I-III disease, initiated NACT, underwent definitive breast surgery, and had available surgical pathology reports. We compared pathologic complete response (pCR) rates among women with and without HIV infection, using multivariable logistic regression to control for differences in tumor characteristics. We also evaluated the impact of HIV infection on pCR within subgroups based on patient and tumor factors. RESULTS Of 715 women, the 173 (24.2%) WLWH were less likely to achieve pCR than women without HIV (8.7% vs 16.4%, [odds ratio (OR) 0.48, 95% confidence interval (95% CI) 0.27-0.86]). WLWH continued to have lower likelihood of achieving pCR on multivariable analysis (OR 0.52, 95% CI 0.28-0.98). A similar pattern was seen within subgroups, although HIV infection appeared to affect pCR more in ER/PR-positive BC (OR 0.24, 95% CI 0.08-0.71) than in ER/PR-negative BC (OR 0.94, 95% CI 0.39-2.29). CONCLUSION WLWH were less like to achieve pCR following NACT for BC than women without HIV. This reduced response to systemic therapy may contribute to the poorer BC outcomes seen in WLWH.

Abstract
PURPOSE The incidence and predictors of diabetes (DM) in patients with breast cancer (BC) were evaluated. We compared DM incidence and physician access in BC patients to matched controls. METHODS We identified women with stage I-III BC diagnosed from 2005 to 2013 in the SEER-Medicare database, with ≥ 2 years of follow-up after diagnosis, without previous DM claims. Incident DM was determined by ≥ 1 DM claims after BC diagnosis. Multivariable analysis was used to identify factors associated with incident DM. Age- and race-matched non-cancer controls were obtained from a 5% random sample and assigned an index date. Physician and PCP visits per-patient-per-year were compared between cases and controls in the two-year period prior to and after the index date. RESULTS Among 14,506 eligible BC patients, 3234 (22.3%) developed DM versus 16.5% of controls. Among BC patients, factors associated with incident DM included race (Black OR 1.63 95% CI 1.39-1.93, Hispanic OR 3.03 95% CI 1.92-4.81; vs. Caucasians), SES (Quintile 0 vs. Quintile 4 OR 1.55 95% CI 1.33-1.78), and receipt of chemotherapy (vs. none OR 1.19 95% CI 1.08-1.31). Among cases and controls, respectively, median physician visits per-patient-per-year were 19 and 17 prior to the index date, and 46 and 19 after the index date; median PCP visits were 2 for both groups in both periods. CONCLUSION About 22% of BC patients developed DM, more than controls in the same period. While there were differences in healthcare access, there weren't differences in PCP access between groups. This represents an opportunity for better comorbidity management in BC patients.

Abstract
Multimorbidity in women with breast cancer may delay presentation, affect treatment decisions and outcomes. We described the multimorbidity profile of women with breast cancer, its determinants, associations with stage at diagnosis and treatments received. We collected self-reported data on five chronic conditions (hypertension, diabetes, cerebrovascular diseases, asthma/chronic obstructive pulmonary disease, tuberculosis), determined obesity using body mass index (BMI) and tested HIV status, in women newly diagnosed with breast cancer between January 2016 and April 2018 in five public hospitals in South Africa. We identified determinants of ≥2 of the seven above-mentioned conditions (defined as multimorbidity), multimorbidity itself with stage at diagnosis (advanced [III-IV] vs. early [0-II]) and multimorbidity with treatment modalities received. Among 2,281 women, 1,001 (44%) presented with multimorbidity. Obesity (52.8%), hypertension (41.3%), HIV (22.0%) and diabetes (13.7%) were the chronic conditions that occurred most frequently. Multimorbidity was more common with older age (OR = 1.02; 95% CI 1.01-1.03) and higher household socioeconomic status (HSES) (OR = 1.06; 95% CI 1.00-1.13). Multimorbidity was not associated with advanced-stage breast cancer at diagnosis, but for self-reported hypertension there was less likelihood of being diagnosed with advanced-stage disease in the adjusted model (OR 0.80; 95% CI 0.64-0.98). Multimorbidity was associated with first treatment received in those with early-stage disease, p = 0.003. The prevalence of multimorbidity is high among patients with breast cancer. Our findings suggest that multimorbidity had a significant impact on treatment received in those with early-stage disease. There is need to understand the impact of multimorbidity on breast cancer outcomes.

Abstract
BACKGROUND Patients co-infected with hepatitis B virus (HBV) and the human immunodeficiency virus (HIV) are at risk of developing hepatocellular carcinoma (HCC). In sub-Saharan Africa, the overlap between high HIV and HBV prevalence may increase the incidence of HCC. This study investigated the impact of HBV/HIV co-infection on age at presentation and survival of HCC. METHODS Ethical approval was obtained to recruit, following informed written consent, patients diagnosed with HCC at oncology units at four South African hospitals. Between December 2012 and August 2015, patients newly diagnosed with HCC were recruited and provided demographic and clinical data and blood specimens. Patients were tested for HBV, hepatitis C virus (HCV) and HIV. Survival data was available for a subset of patients. RESULTS Of 107 HCC cases, 83 (78%) were male. Median age was 46 years (range 18 to 90 years), 68/106 (64%) were HBsAg-positive, and 22/100 (22%) were HIV infected. Among HBV surface antigen (HBsAg)-positive HCC cases, 18/66 (27%) were HIV-infected compared to 3/34 (9%) among those that were HBsAg-negative (p = 0.04). A greater proportion of HBV/HIV co-infected cases were female than HBV mono-infected (6/18, 33% vs 6/47, 13%; p = 0.005). In addition, HBV/HIV co-infected females presented at a younger mean age (36.8 years) than HBV mono-infected women (50.5 years) (p = 0.09). Median survival was 82 days among the HIV-infected HCC patients compared to 181 days among those without HIV (p = 0.15). CONCLUSIONS HCC is an important complication in the HIV/HBV infected patient. HIV-positive patients presented with HCC at a younger age than HIV-negative patients, this effect appears to be greater in women. These data provide more evidence supporting the call to address. HCC as a cause of morbidity and mortality in the HBV/HIV co-infected patient population. (281 words).

Abstract
CONTEXT When religious and spiritual (R/S) care needs of patients with advanced disease are met, their quality of life (QoL) improves. We studied the association between R/S support and QoL of patients with cancer at the end of life in Soweto, South Africa. OBJECTIVES To identify R/S needs among patients with advanced cancer receiving palliative care services and to assess associations of receipt of R/S care with patient QoL and place of death. METHODS A prospective cohort study conducted from May 1, 2016 to April 30, 2018 at a tertiary hospital in Soweto, South Africa. Nurses enrolled patients with advanced cancer and referred them to the palliative care multidisciplinary team. Spiritual counselors assessed and provided spiritual care to patients. We compared sociodemographic, clinical, and R/S factors and QoL of R/S care recipients and others. RESULTS Of 233 deceased participants, 92 (39.5%) had received R/S care. Patients who received R/S care reported less pain (2.82 ± 1.23 vs. 1.93 ± 1.69), used less morphine, and were more likely to die at home than patients who did not (57.5% compared with 33.7%). On multivariate logistic regression analysis, adjusting for significant confounding influences and baseline African Palliative Care Association Palliative care Outcome Scale scores, receipt of spiritual care was associated with reduced pain and family worry (odds ratio 0.33; 95% CI 0.11-0.95 and odds ratio 3.43; 95% CI 1.10-10.70, respectively). CONCLUSION Patients with cancer have R/S needs. R/S care among our patients appeared to improve their end-of-life experience. More research is needed to determine the mechanisms by which R/S care may have improved the observed patient outcomes.

Abstract
Although prostate cancer is the leading cause of cancer mortality for African men, the vast majority of known disease associations have been detected in European study cohorts. Furthermore, most genome-wide association studies have used genotyping arrays that are hindered by SNP ascertainment bias. To overcome these disparities in genomic medicine, the Men of African Descent and Carcinoma of the Prostate (MADCaP) Network has developed a genotyping array that is optimized for African populations. The MADCaP Array contains more than 1.5 million markers and an imputation backbone that successfully tags over 94% of common genetic variants in African populations. This array also has a high density of markers in genomic regions associated with cancer susceptibility, including 8q24. We assessed the effectiveness of the MADCaP Array by genotyping 399 prostate cancer cases and 403 controls from seven urban study sites in sub-Saharan Africa. Samples from Ghana and Nigeria clustered together, whereas samples from Senegal and South Africa yielded distinct ancestry clusters. Using the MADCaP array, we identified cancer-associated loci that have large allele frequency differences across African populations. Polygenic risk scores for prostate cancer were higher in Nigeria than in Senegal. In summary, individual and population-level differences in prostate cancer risk were revealed using a novel genotyping array. SIGNIFICANCE: This study presents an Africa-specific genotyping array, which enables investigators to identify novel disease associations and to fine-map genetic loci that are associated with prostate and other cancers.

Abstract
PURPOSE Breast cancer (BC) incidence is rising in sub-Saharan Africa, and approximately 75% of cases are diagnosed at stages III and IV. Women living with HIV, who are surviving longer with antiretroviral use, are also increasingly affected. Survey data suggest that primary care providers often fail to recognize early-stage BC. We trained nurses from 5 antiretroviral clinics in Eswatini to assess breast abnormalities and evaluated our curriculum’s effectiveness in improving BC knowledge and skills. METHODS The 2-day curriculum covered breast physiology, benign pathology, and BC. Clinical breast exam and management were taught using mannequins and standardized patient scenarios, with emphasis on prompt referral for biopsy. After training, mentoring was provided every 2 to 4 weeks at each study clinic. A written examination of BC knowledge (maximum score, 23 points) and an observed examination of practical clinical skills (maximum score, 28 points) were administered before training, immediately after training, and 90 days after training. Pre- and post-training scores were compared using Wilcoxon signed-rank tests. RESULTS Forty-four nurses, with a median of 10 years of experience, underwent training; only 5 nurses (11%) reported prior BC education. All nurses completed the pre- and immediate post-training exams, and 38 completed the 90-day post-training exams. Median scores on pre-, immediate post-, and 90-day post-training knowledge exams were 17.5 (interquartile range [IQR], 16-19), 20 (IQR, 19-21), and 20 (IQR, 19-21), respectively. Median scores on pre-, immediate post-, and 90-day post-training practical exams were 10 (IQR, 7-11), 23 (IQR, 21.5-25), and 23 (IQR, 22-24), respectively. Compared with pretraining scores, immediate post- and 90-day post-training scores on both exams were significantly improved ( P < .0001 for all comparisons). CONCLUSION Our curriculum produced a sustained improvement in nurses’ BC-related knowledge and clinical skills, including identification of possible early cancers. Our results resemble those among similarly trained Rwandan nurses, suggesting that the curriculum may generally benefit front-line health care providers and patients in sub-Saharan Africa.

Abstract
PURPOSE Nonadherence to aromatase inhibitors (AIs) for breast cancer is common and increases the risk of recurrence. Text messaging increases adherence to medications for chronic conditions. METHODS We conducted a randomized clinical trial of text messaging (TM) versus no text messaging (No-TM) at 40 sites in the United States. Eligible patients were postmenopausal women with early-stage breast cancer taking an AI for > 30 days with a planned duration of ≥ 36 months. Test messages were sent twice a week over 36 months. Content themes focused on overcoming barriers to medication adherence and included cues to action, statements related to medication efficacy, and reinforcements of the recommendation to take AIs. Both groups were assessed every 3 months. The primary outcome was time to adherence failure (AF), where AF was defined as urine AI metabolite assay results satisfying one of the following: < 10 ng/mL, undetectable, or no submitted specimen. A stratified log-rank test was conducted. Multiple sensitivity analyses were performed. RESULTS In total, 724 patients were registered between May 2012 and September 2013, among whom,702 patients (348 in the text-messaging arm and 354 in the no-text-messaging arm) were eligible at baseline. Observed adherence at 36 months was 55.5% for TM and 55.4% for No-TM. The primary analysis showed no difference in time to AF by arm (3-year AF: 81.9% TM v 85.6% No-TM; HR, 0.89 [95% CI, 0.76 to 1.05]; P = .18). Multiple time to AF sensitivity analyses showed similar nonsignificant results. Three-year self-reported time to AF (10.4% v 10.3%; HR, 1.16 [95% CI, 0.69 to 1.98]; P = .57) and site-reported time to AF (21.9% v 18.9%; HR, 1.31 [95% CI, 0.86 to 2.01]; P = .21) also did not differ by arm. CONCLUSION To our knowledge, this was the first large, long-term, randomized trial of an intervention directed at improving AI adherence. We found high rates of AI AF. Twice-weekly text reminders did not improve adherence to AIs. Improving long-term adherence will likely require personalized and sustained behavioral interventions.

Abstract
Background Racial/ethnic differences in mortality have not been well studied for either non‐cardia gastric cancer (NCGC) or cardia gastric cancer (CGC). The aim of this study was to examine the US mortality rates for these cancer subtypes, as well as esophageal adenocarcinoma (EAC) as a comparator. Methods We identified 14 164 individuals who died from NCGC, 5235 from CGC, and 13 982 from EAC in the Surveillance, Epidemiology, and End Results database between 2004 and 2016. Age‐adjusted incidence‐based mortality rates and corresponding annual percent changes (APCs) were calculated. Analyses were stratified by race/ethnicity, age, and stage of disease at diagnosis. Results The mortality rate in NCGC was two‐ to threefold higher in blacks, Hispanics, and Asians/Pacific Islanders (PI) than non‐Hispanic whites, and was significant across all age groups and stages of disease (P < .01). Mortality in CGC was higher in non‐Hispanic whites than blacks and Asians/PI, particularly in individuals in the 50‐64 year age group and those with stage IV disease. Mortality in EAC was two‐ to sixfold higher in non‐Hispanic whites than all other groups across all age groups and stages of disease. From 2004 to 2016, mortality rates were stable across all racial/ethnic groups in NCGC and CGC, and in minority groups with EAC, but have been rising in non‐Hispanic whites with EAC (APC 3.03, 95% CI 0.17‐5.96). Conclusions This is the largest study of incidence‐based mortality in CGC and NCGC and demonstrates racial/ethnic differences in mortality between these subtypes. Mortality rates for NCGC are highest in minority groups, and have been stable in recent years despite declining incidence. Mortality rates for CGC are marginally higher in middle‐aged non‐Hispanic whites with advanced disease, though have remained stable. In contrast, mortality in EAC has been rising for non‐Hispanic whites, in parallel to incidence. Further studies are needed to refine prevention strategies for high‐risk individuals dying from these specific cancer subtypes.

Abstract
Background Estrogen metabolite concentrations of 2-hydroxyestrone (2-OHE1) and 16-hydroxyestrone (16-OHE1) may be associated with breast carcinogenesis. However, no study has investigated their possible impact on mortality after breast cancer. Methods This population-based study was initiated in 1996–1997 with spot urine samples obtained shortly after diagnosis (mean = 96 days) from 683 women newly diagnosed with first primary breast cancer and 434 age-matched women without breast cancer. We measured urinary concentrations of 2-OHE1 and 16-OHE1 using an enzyme-linked immunoassay. Vital status was determined via the National Death Index (n = 244 deaths after a median of 17.7 years of follow-up). We used multivariable-adjusted Cox proportional hazards to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the estrogen metabolites-mortality association. We evaluated effect modification using likelihood ratio tests. All statistical tests were two-sided. Results Urinary concentrations of the 2-OHE1 to 16-OHE1 ratio (>median of 1.8 vs ≤median) were inversely associated with all-cause mortality (HR = 0.74, 95% CI = 0.56 to 0.98) among women with breast cancer. Reduced hazard was also observed for breast cancer mortality (HR = 0.73, 95% CI = 0.45 to 1.17) and cardiovascular diseases mortality (HR = 0.76, 95% CI = 0.47 to 1.23), although the 95% confidence intervals included the null. Similar findings were also observed for women without breast cancer. The association with all-cause mortality was more pronounced among breast cancer participants who began chemotherapy before urine collection (n = 118, HR = 0.42, 95% CI = 0.22 to 0.81) than among those who had not (n = 559, HR = 0.98, 95% CI = 0.72 to 1.34; Pinteraction = .008). Conclusions The urinary 2-OHE1 to 16-OHE1 ratio may be inversely associated with long-term all-cause mortality, which may depend on cancer treatment status at the time of urine collection.

Abstract
OBJECTIVE To examine patterns of patient travel among women with ovarian cancer and to explore the association between travel distance and short and long-term outcomes. METHODS Women with stage II-IV epithelial ovarian cancer diagnosed from 2004 to 2016 who underwent primary surgery were identified in the National Cancer Database. Mixed-effect log-linear models and proportional hazards models were developed to evaluate the association between travel distance and short and long-term outcomes after propensity score weighting. A further analysis was performed to compare patients who traveled a short distance to a low volume center (Local) to patients who traveled farther to a high volume hospital (Travel). RESULTS We identified 56,834 patients treated in 1201 hospitals. Hispanic women were 58% and black women 64% less likely than white women to travel to a center in the greatest distance quartile for care. Similarly, Medicaid recipients (vs. commercially insured) were less likely to travel to a quartile four hospital (compared to Q1 of distance traveled). Of all patients, 90-day mortality was significantly lower in patients who traveled farther (Q4 vs. Q1; P < 0.0001). Compared to women in the Local group, patients in the Travel group had a decreased 30-day readmission rate. There was no difference in 30-day, 90-day, or 5-year mortality when comparing the Local to the Travel group. CONCLUSIONS Travel distance for ovarian cancer surgery has increased over time. While there may be some short-term benefits in traveling to a regional center for care, there was little difference in long term outcomes based on travel distance.

Abstract
PURPOSE The quality of breast cancer care in sub-Saharan Africa contributes to the region’s dismal breast cancer mortality. ASCO has issued quality measures focusing on delivery of adjuvant chemotherapy, radiotherapy, and endocrine therapy. We applied these measures in five South African public hospitals and analyzed factors associated with care concordance. MATERIALS AND METHODS Among 1,736 women with breast cancer who were enrolled in the South African Breast Cancer and HIV Outcomes study over 24 months, we evaluated care using ASCO’s three measures. We also evaluated adjuvant chemotherapy receipt in 957 women with an indication. We used logistic regression to estimate associations between measure-concordant care and patient factors. RESULTS Of 235 women with hormone receptor–negative cancer, 173 (74%) began adjuvant chemotherapy within 120 days from diagnosis. Of 194 patients who received breast-conserving surgery, 73 (37%) began radiotherapy within 365 days from diagnosis. Of 999 women with hormone receptor–positive cancer, 719 (72%) initiated endocrine therapy within 365 days from diagnosis. Chemotherapy and radiotherapy measure-concordant care were more common among women residing < 20 km from the hospital (odds ratio [OR], 1.79; 95% CI, 1.32 to 2.44 and OR, 3.17; 95% CI, 1.57 to 6.42). Endocrine therapy measure-concordant care was more common among English-speaking women (OR, 2.12; 95% CI, 1.12 to 4.02). Participating hospitals varied in care concordance. HIV infection did not affect care quality. CONCLUSION More timely delivery of chemotherapy, radiotherapy, and endocrine therapy is needed in South Africa, particularly for women living > 20 km from the hospital or not speaking English. Focused quality improvement efforts could support that goal.

Abstract
12019 Background: Non-adherence to aromatase inhibitors (AIs) for breast cancer is common and increases risk of recurrence. Few prospective studies have systematically evaluated factors associated with non-adherence. We analyzed baseline sociodemographic, prescription, and patient reported outcome (PRO) symptoms and quality-of-life to identify factors associated with non-adherence prospectively over 3-years. Methods: Patients enrolled in SWOG S1105 were required to have been on an AI for ≥30 days. Patients were assessed for non-adherence to AIs every 3 months for 36 months, with non-adherence defined as urine AI metabolite assay results satisfying any of the following: < 10 ng/mL, undetectable, specimen submitted outside of the ± 21 day follow-up appointment window, or no submitted specimen. At baseline patients were asked about insurance, pill number dispensed and medication cost, and they completed PROs focused on pain and endocrine symptoms (BPI (Brief Pain Inventory), FACT-ES (Endocrine Symptoms)), as well as their beliefs about medications (TSQM (Treatment Satisfaction Questionnaire for Medicine) and BMQ (Brief Medication Questionnaire)). PRO scales were split at the median creating high vs low binary predictors. We determined the association of baseline factors and non-adherence at 36 months. We also evaluated an adverse risk model for AI non-adherence by summing the number of statistically significant adverse factors associated with non-adherence. Logistic regression was used. Results: In total, 724 patients were registered from 40 institutions between May, 2012 and September, 2013. The median age was 60.9 years, and 64.5% were on AI < 12 months prior to registration. Overall, 35.9% were non-adherent at 36 months. Younger patients ( < 65 years) were less adherent (39% vs. 29% non-adherence, OR = 1.51, p = 0.02). Baseline scores on the BPI, FACT-ES, BMQ and TSQM were each statistically significantly associated with AI adherence. Non-adherence was significantly higher among patients scoring poorly on all 4 PRO instruments (65%) compared to those scoring poorly 0 or 1 PRO instruments (27%; OR, 4.68 [2.84-7.73], p < .0001). For each increase in the number of adverse risk PRO scores, the risk of non-adherence increased by 45% (OR = 1.45, p < .0001). Similar results were found when age was included in the score. Conclusions: Presence of multiple baseline risk factors identified through PRO instruments increases non-adherence to AI’s 4-fold. Use of PROs can identify patients for targeted interventions to improve adherence.

Abstract
Among men in South Africa, the prevalence of tobacco smoking is as high as 33%. Although smoking is responsible for most lung cancer in South Africa, occupational and environmental exposures contribute greatly to risk. We conducted a tobacco and lung cancer screening needs assessment and administered surveys to adults who smoked >100 cigarettes in their lifetime in Johannesburg (urban) and Kimberley (rural). We compared tobacco use, risk exposure, attitudes toward and knowledge of, and receptivity to cessation and screening, by site. Of 324 smokers, nearly 85% of current smokers had a <30 pack-year history of smoking; 58.7% had tried to stop smoking ≥1 time, and 78.9% wanted to quit. Kimberley smokers more often reported being advised by a healthcare provider to stop smoking (56.5% vs. 37.3%, p=0.001) than smokers in Johannesburg but smokers in Johannesburg were more willing to stop smoking if advised by their doctor (72.9% vs. 41.7%, p<0.001). Findings indicate that tobacco smokers in two geographic areas of South Africa are motivated to stop smoking but receive no healthcare support to do so. Developing high risk criteria for lung cancer screening and creating tobacco cessation infrastructure may reduce tobacco use and decrease lung cancer mortality in South Africa.

Abstract
PURPOSE We investigated whether the relationship between diabetes and all-cause and CVD-related mortality differed between women with and without breast cancer among a cohort drawn from the same source population. METHODS We interviewed 1,363 women newly diagnosed with breast cancer in 1996-1997, and 1,358 age-matched women without breast cancer, to assess history of physician-diagnosed diabetes. All-cause (n = 631) and CVD-specific mortality (n = 234) was determined by the National Death Index through 2009. We estimated multivariable-adjusted hazard ratios (HRs) for the rates of all-cause and CVD-specific mortality and, to account for competing causes of death, and subdistribution HRs (sHRs) for risk of CVD-related death. RESULTS Among women with and without breast cancer, respectively, diabetes was associated with: all-cause mortality [HR (95% CI) 1.52 (1.13, 2.05) and 2.17 (1.46, 3.22)]; CVD-specific deaths [1.74 (1.06, 2.84) and 2.06 (1.11, 3.84)]; and risk of CVD-related death [sHR 1.36 (0.81, 2.27) and 1.79 (0.94, 3.40)]. Differences in effect estimates between women with and without breast cancer did not reach statistical significance (p-interaction > 0.10). CONCLUSION We found that the positive association between a history of physician-diagnosed diabetes and risk of all-cause and CVD-related mortality is of similar magnitude among a population-based cohort of women with or without breast cancer.

Abstract
OBJECTIVE To examine the risk of nodal metastases in a contemporary cohort of women based on pathologic risk factors including histology, depth of invasion, tumor grade, and lymphovascular space invasion. METHODS Women with endometrial cancer who underwent hysterectomy from 2004 to 2016 who were registered in the National Cancer Database were analyzed. Patients were stratified by T stage: T1A (<50% myometrial invasion), T1B (>50% myometrial invasion) and T2 (cervical involvement). Lymph node metastases were assessed in relation to tumor T stage and grade, and further stratified by lymphovascular space invasion. RESULTS We identified 161,960 patients. The rate of nodal metastases within the endometrioid histology cohort was 2.2% for T1A cancers, 12.8% for T1B cancers and 19.9% for T2 cancers. For stage TIA cancers, the percent of patients with positive nodes increased from 1.1% for grade 1 cancers, to 2.9% for grade 2 cancers to 4.8% for grade 3 cancers. The corresponding rates of nodal metastases for stage T1B cancers were 8.6%, 13.7%, and 16.9%, respectively. For T1A cancers without lymphovascular space invasion, nodal metastases ranged from 0.6% in those with grade 1 cancers to 3.0% for grade 3 cancers. The corresponding risk of nodal disease ranged from 11.8% to 13.9% for T1A cancers with lymphovascular space invasion. CONCLUSIONS There was a sequential increase in the risk of lymph node metastases based on depth of uterine invasion, tumor grade, and the presence of lymphovascular space invasion. The overall rate of nodal metastasis is lower than reported in the original GOG 33.

Cost-Effectiveness Analysis of Biomarker-Guided Treatment for Metastatic Gastric Cancer in the Second-Line Setting. JOURNAL OF ONCOLOGY 2020; 2020:2198960. [PMID: 32148492 PMCID: PMC7048937 DOI: 10.1155/2020/2198960] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Accepted: 12/26/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND The 5-year survival rate of patients with metastatic gastric cancer (GC) is only 5%. However, trials have demonstrated promising antitumor activity for targeted therapies/immunotherapies among chemorefractory metastatic GC patients. Pembrolizumab has shown particular efficacy among patients with programmed death ligand-1 (PD-L1) expression and high microsatellite instability (MSI-H). The aim of this study was to assess the effectiveness and cost-effectiveness of biomarker-guided second-line GC treatment. METHODS We constructed a Markov decision-analytic model using clinical trial data. Our model compared pembrolizumab monotherapy and ramucirumab/paclitaxel combination therapy for all patients and pembrolizumab for patients based on MSI status or PD-L1 expression. Paclitaxel monotherapy and best supportive care for all patients were additional comparators. Costs of drugs, treatment administration, follow-up, and management of adverse events were estimated from a US payer perspective. The primary outcomes were quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) with a willingness-to-pay threshold of $100,000/QALY over 60 months. Secondary outcomes were unadjusted life years (survival) and costs. Deterministic and probabilistic sensitivity analyses were performed to evaluate model uncertainty. RESULTS The most effective strategy was pembrolizumab for MSI-H patients and ramucirumab/paclitaxel for all other patients, adding 3.8 months or 2.0 quality-adjusted months compared to paclitaxel. However, this strategy resulted in a prohibitively high ICER of $1,074,620/QALY. The only cost-effective strategy was paclitaxel monotherapy for all patients, with an ICER of $53,705/QALY. CONCLUSION Biomarker-based treatments with targeted therapies/immunotherapies for second-line metastatic GC patients substantially improve unadjusted and quality-adjusted survival but are not cost-effective at current drug prices.

Abstract
Although genetic factors such as family history have been associated with increased risk of developing colorectal cancer (CRC), multiple lifestyle and environmental risk factors for CRC have been identified, including smoking, diet, obesity, and physical activity.1,2 Although couples typically have different genetic backgrounds, spouses are likely to share lifestyle and environmental exposures over the course of years, including similar home environments, geographical locations of residence, dietary exposures, and smoking exposures.3 As such, one might expect that an increased CRC incidence would be seen among spouses of patients with CRC; however, studies on this topic have inconsistent results.3-6 By using a large cohort of spouses who have undergone colonoscopy, we aimed to determine whether the risk of colorectal adenomas is increased among spouses of those with colorectal neoplasia (CRN) on colonoscopy.
