[PMID: 38628960 PMCID: PMC11020713 DOI: 10.1177/11782234241240171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 02/29/2024] [Indexed: 04/19/2024] Open
Abstract
Background Endocrine therapy (ET) adherence leads to increased survival in breast cancer (BC). How follow-up should be done to maximize adherence is not known. Objectives To assess adherence to ET, factors favouring adherence to ET and effects on survival in a population-based cohort of BC patients in western Sweden. Design This is a retrospective study. Methods We included 358 patients operated for oestrogen receptor-positive BC and recommended 5 years of ET, in Region Halland, Sweden, year 2015 to 2016. Demographical, clinical and pathological data and use of ET were retrieved from the electronic medical records. Patients were considered adherent if taking ET for 5 years or during the full extent of the follow-up, until termination of ET due to BC relapse or death and where renewals of prescriptions of ET covered ⩾80% of the ordinated dose. Two follow-up routines were employed, ie, routine A where patients were contacted annually by nurses and a more passive follow-up routine B where patients were only contacted by nurses at 2 years and 5 years following start of ET. Results Medication persistence for 4 years and more was good and similar between patients initiating aromatase inhibitor (AI) and tamoxifen (75.7% and 72.0%, respectively, P = .43). More patients initiating AIs changed ET due to side effects compared with patients initiating tamoxifen (24.3% vs 9.9%, respectively, P < .0001). Endocrine therapy adherence was better for follow-up routine B than for follow-up routine A (hazard ratio [HR] = 2.71 [1.44-5.09], P = .0027). Conclusions Adherence to ET in BC is high in Western Sweden. Less regular nurse-initiated contacts between BC patients and nursesled surprisingly to a better adherence than a more regular nurse-initiated contact.

J Breast Cancer 2023; 26:309-333. [PMID: 37272247 PMCID: PMC10475712 DOI: 10.4048/jbc.2023.26.e22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/05/2023] [Accepted: 04/16/2023] [Indexed: 06/06/2023] Open
Abstract
PURPOSE Adherence and persistence to adjuvant hormone therapy (AHT) are seldom maintained among early-stage hormone receptor-positive breast cancer (BC) survivors, despite the significant clinical benefits of long-term AHT. As the factors influencing adherence to AHT remain unclear, this study aimed to comprehensively identify such factors and classify them into specific dimensions. METHODS PubMed, Cochrane Library, Embase, PsycINFO, and CINAHL were searched for qualified articles. The search mainly focused on three components: early-stage (0-III) BC, oral AHT administration, and adherence to AHT, with keywords derived from MeSH and entry terms. The factors identified were then classified into six categories based on a modified WHO multidimensional model. RESULTS Overall, 146 studies were included; the median sample size was 651 (range, 31-40,009), and the mean age of the population was 61.5 years (standard deviation, 8.3 years). Patient- and therapy-related factors were the most frequently investigated factors. Necessity/concern beliefs and self-efficacy among patient-related factors were consistently related to better adherence than depression. Although drug side effects and medication use cannot be modified easily, a refined prescription strategy for the initiation and switching of AHT is likely to increase adherence levels. CONCLUSION An effective psychological program that encourages positive views and beliefs about medication and management strategies for each therapy may be necessary to improve adherence to AHT. Social support and a sense of belonging can be enhanced through community participation and social media for better adherence to AHT. Patient-centered communication and appropriate recommendations by physicians may be attributable to better adherence outcomes. Findings from systematically organized factors that influence adherence to AHT may contribute to the establishment of intervention strategies to benefit patients with early-stage BC to achieve optimal health.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PAC) has one of the highest mortality rates among all malignancies. While previous research has analyzed socioeconomic factors' effect on PAC survival, outcomes of Medicaid patients are understudied. METHODS Using the SEER-Medicaid database, we studied non-elderly, adult patients with primary PAC diagnosed between 2006 and 2013. Five-year disease-specific survival analysis was performed using the Kaplan-Meier method and adjusted analysis using Cox proportional-hazards regression. RESULTS Among 15,549 patients (1799 Medicaid, 13,750 non-Medicaid), Medicaid patients were less likely to receive surgery (p < .001) and more likely to be non-White (p < .001). The 5-year survival of non-Medicaid patients (8.13%, 274 days [270-280]) was significantly higher than that of Medicaid patients (4.97%, 152 days, [151-182], p < .001). Among Medicaid patients, those in high poverty areas had significantly lower survival rates (152 days [122-154]) than those in medium poverty areas (182 days [157-213], p = .008). However, non-White (152 days [150-182]) and White Medicaid patients (152 days [150-182]) had similar survival (p = .812). On adjusted analysis, Medicaid patients were still associated with a significantly higher risk of mortality (aHR 1.33 [1.26-1.41], p < .0001) compared to non-Medicaid patients. Unmarried status and rurality were associated with a higher risk of mortality (p < .001). DISCUSSION Medicaid enrollment prior to PAC diagnosis was generally associated with a higher risk of disease-specific mortality. While there was no difference in the survival between White and non-White Medicaid patients, Medicaid patients living in high poverty areas were shown to be associated with poor survival.

Abstract
Black women in the US have significantly higher breast cancer mortality than White women. Within biomarker-defined tumor subtypes, disparate outcomes seem to be limited to women with hormone receptor positive and HER2 negative (HR+/HER2-) breast cancer, a subtype usually associated with favorable prognosis. In this review, we present data from an array of studies that demonstrate significantly higher mortality in Black compared to White women with HR+/HER2-breast cancer and contrast these data to studies from integrated healthcare systems that failed to find survival differences. Then, we describe factors, both biological and non-biological, that may contribute to disparate survival in Black women.

Preventing metastatic recurrence in low-risk ER/PR + breast cancer patients-a retrospective clinical study exploring the evolving challenge of persistence with adjuvant endocrine therapy. Breast Cancer Res Treat 2023; 198:31-41.

Abstract
PURPOSE In the genomic era, more women with low-risk breast cancer will forego chemotherapy and rely on adjuvant endocrine therapy (AET) to prevent metastatic recurrence. However, some of these patients will unfortunately relapse. We sought to understand this outcome. Preliminary work suggested that early discontinuation of AET, also known as non-persistence, may play an important role. A retrospective analysis exploring factors related to our breast cancer patients' non-persistence with AET was performed. METHODS Women who underwent Oncotype-DX® testing between 2011 and 2014 with minimum 5 years follow-up were included. 'Low risk' was defined as Oncotype score < 26. Outcomes of recurrence and persistence were determined by chart review. Patient, tumor and treatment factors were collected, and persistent versus non-persistent groups compared using multivariable ANOVA and Fisher Chi square exact test. RESULTS We identified six cases of distant recurrence among low-risk patients with a median follow-up of 7.7 years. Among them, five of six patients (83%) were non-persistent with AET. The non-persistence rate in our cohort regardless of recurrence was 57/228 (25%). Non-persistent patients reported more severe side effects compared with persistent patients (p = 0.002) and were more likely to be offered a switch in endocrine therapy, rather than symptom-relief (p = 0.006). In contrast, persistent patients were 10.3 times more likely to have been offered symptom-alleviating medications compared with non-persistent patients (p < 0.001). A subset analysis revealed that patients who persisted with therapy had a higher Oncotype-DX® score than patients who discontinued early (p = 0.028). CONCLUSION Metastatic recurrence in low-risk breast cancer patients may be primarily due to non-persistence with endocrine therapy. Further work is needed to optimize care for patients who struggle with side effects. To our knowledge, these are the first published data suggesting that Oncotype-DX® score may influence persistence with AET.

JAMA Netw Open 2022; 5:e2225345. [PMID: 35921108 PMCID: PMC9350715 DOI: 10.1001/jamanetworkopen.2022.25345] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/05/2023] Open
Abstract
IMPORTANCE Though adjuvant endocrine therapy (AET) has proven efficacy in treating hormone receptor-positive (HR-positive) breast cancer, patient adherence to AET and continuation of treatment as recommended by guidelines remain suboptimal, especially for low-income patients. OBJECTIVE To quantify timelines for initiating AET and assess their association with short- and long-term adherence and continuation of AET in low-income women with breast cancer. DESIGN, SETTING, AND PARTICIPANTS This population-based retrospective cohort study included women younger than 65 years diagnosed with first primary HR-positive breast cancer between January 1, 2007, and December 31, 2013, followed up for 5 years after the first use of AET through December 2018, and identified from the linked Missouri Cancer Registry and Medicaid claims data set. EXPOSURES Time to initiation (TTI) as days from the date of last treatment (surgery, radiotherapy, or chemotherapy) to the first date of AET prescription fill. MAIN OUTCOMES AND MEASURES The main outcomes were adherence to AET as medication possession ratio of 80% or greater and continuation of AET as no gap in medication supply for at least 90 days. Odds ratios (ORs) of adherence and continuation over 1 to 5 years were estimated using logistic regression adjusted for demographic, clinical, and neighborhood variables. Analyses were performed between September 1, 2020, and May 31, 2022. RESULTS Among 1711 patients, median TTI was 53 (IQR, 26-117) days. A total of 1029 patients (60.1%) were aged 50 to 64 years old, 1270 (74.2%) were non-Hispanic White, and 1133 (66.2%) were unmarried. In the first year after initiation, 1317 (77.0%) were adherent and 1015 (59.3%) continued AET. Over the full 5 years, 376 (22.0%) were adherent and 409 (23.9%) continued AET. Longer TTI was significantly associated with poorer adherence at every year, with an OR of 0.97 (95% CI, 0.95-0.99) for 1-year adherence and an OR of 0.94 (95% CI, 0.90-0.97) for 5-year adherence per 1-month increase in TTI. Longer TTI was also associated with lower odds of short-term, but not long-term, continuation (OR, 0.97 [95% CI, 0.95-0.99] for 1-year continuation and 0.98 [95% CI, 0.96-0.99] for 2-year continuation). CONCLUSIONS AND RELEVANCE In this cohort study, longer time to AET initiation was associated with lower odds of short-term and long-term adherence to AET in Medicaid-insured patients with breast cancer. Therefore, early interventions targeting treatment initiation timelines may positively impact adherence throughout the course of treatment and, therefore, outcomes.

Abstract
The COVID-19 pandemic has had critical consequences for cancer care delivery, including altered treatment protocols and delayed services that may affect patients’ quality of life and long-term survival. Breast cancer patients from minoritized racial and ethnic groups already experience worse outcomes, which may have been exacerbated by treatment delays and social determinants of health (SDoH). This protocol details a mixed-methods study aimed at comparing cancer care disruption among a diverse sample of women (non-Hispanic White, non-Hispanic Black/African American, and Hispanic/Latina) and assessing how proximal, intermediate, and distal SDoH differentially contribute to care continuity and health-related quality of life. An embedded mixed-methods design will be implemented. Eligible participants will complete an online survey, followed by a semi-structured interview (with a subset of participants) to further understand factors that influence continuity of care, treatment decision-making, and self-reported engagement. The study will identify potentially modifiable factors to inform future models of care delivery and improve care transitions. These data will provide the necessary evidence to inform whether a subsequent, multilevel intervention is warranted to improve quality of care delivery in the COVID-19 aftermath. Additionally, results can be used to identify ways to leverage existing social resources to help manage and support patients’ outcomes.

Black and Hispanic women are less likely than white women to receive guideline-concordant endometrial cancer treatment. Am J Obstet Gynecol 2020; 223:398.e1-398.e18. [PMID: 32142825 DOI: 10.1016/j.ajog.2020.02.041] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 02/05/2020] [Accepted: 02/22/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Differences in receipt of guideline-concordant treatment might underlie well-established racial disparities in endometrial cancer mortality. OBJECTIVE Using the National Cancer Database, we assessed the hypothesis that among women with endometrioid endometrial cancer, racial/ethnic minority women would have lower odds of receiving guideline-concordant treatment than white women. In addition, we hypothesized that lack of guideline-concordant treatment was linked with worse survival. STUDY DESIGN We defined receipt of guideline-concordant treatment using the National Comprehensive Cancer Network guidelines. Multivariable logistic regression models were used to compute odds ratios and 95% confidence intervals for associations between race and guideline-concordant treatment. We used multivariable Cox proportional hazards regression models to estimate hazards ratios and 95% confidence intervals for relationships between guideline-concordant treatment and overall survival in the overall study population and stratified by race/ethnicity. RESULTS This analysis was restricted to the 89,319 women diagnosed with an invasive, endometrioid endometrial cancer between 2004 and 2014. Overall, 74.7% of the cohort received guideline-concordant treatment (n = 66,699). Analyses stratified by race showed that 75.3% of non-Hispanic white (n = 57,442), 70.1% of non-Hispanic black (n = 4334), 71.0% of Hispanic (n = 3263), and 72.5% of Asian/Pacific Islander patients (n = 1660) received treatment in concordance with guidelines. In multivariable-adjusted models, non-Hispanic black (odds ratio, 0.92, 95% confidence interval, 0.86-0.98) and Hispanic women (odds ratio, 0.90, 95% confidence internal, 0.83-0.97) had lower odds of receiving guideline-concordant treatment compared with non-Hispanic white women, while Asian/Pacific Islander women had a higher odds of receiving guideline-concordant treatment (odds ratio, 1.11, 95% confidence interval, 1.00-1.23). Lack of guideline-concordant treatment was associated with lower overall survival in the overall study population (hazard ratio, 1.12, 95% confidence interval, 1.08-1.15) but was not significantly associated with overall survival among non-Hispanic black (hazard ratio, 1.09, 95% confidence interval, 0.98-1.21), Hispanic (hazard ratio, 0.92, 95% confidence interval=0.78-1.09), or Asian/Pacific Islander (hazard ratio, 0.90, 95% confidence interval, 0.70-1.16) women. CONCLUSION Non-Hispanic black and Hispanic women were less likely than non-Hispanic white women to receive guideline-concordant treatment, while Asian/Pacific Islander women more commonly received treatment in line with guidelines. Furthermore, in the overall study population, overall survival was worse among those not receiving guideline-concordant treatment, although low power may have had an impact on the race-stratified models. Future studies should evaluate reasons underlying disparate endometrial cancer treatment.

Abstract
OBJECTIVES African American (AA) women with breast cancer (BrCA) have higher mortality than any other race. Differential mortality has been attributed to nonadherence to endocrine therapy (ET). ET can lower the risk of dying by one third; yet 50% to 75% of all women are nonadherent to ET. Despite the wealth of research examining adherence to ET, understanding which groups of women at risk for poor adherence is not well established. The aim of this investigation was to describe ET adherence by race and geographic location among a cohort of younger BrCA survivors. MATERIALS AND METHODS Cancer registry records were linked to administrative data from Medicaid and a private insurance plan in South Carolina. Inclusion criteria included: European American (EA) or AA race, 3 years of continuous enrollment in the insurance plan after diagnosis, and BrCA diagnosis between 2002 and 2010. Adherence was measured by computing a medication possession ratio (MPR) based upon refill service dates and the number of pills dispensed. Adjusted least squared means were calculated by racial and geographic group using analysis of covariance methods. RESULTS The average MPR for EA women was significantly higher at 96% compared with 92% for AA women (P<0.01). After adjustment for years on hormone therapy, age, and number of pharmacies utilized, rural AA women had an average MPR of 90% compared with 95% for EA women (P<0.01). CONCLUSIONS AA women residing in rural areas demonstrate significantly lower adherence compared with their EA counterparts. Interventions are needed to improve adherence that may ameliorate AA mortality disparities.
