Second primary cancer risks according to race and ethnicity among U.S. breast cancer survivors. Int J Cancer 2024; 155:996-1006. [PMID: 38685564 DOI: 10.1002/ijc.34971] [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: 12/20/2023] [Revised: 03/16/2024] [Accepted: 03/26/2024] [Indexed: 05/02/2024]
Abstract
Breast cancer survivors have an increased risk of developing second primary cancers, yet risks by race and ethnicity have not been comprehensively described. We evaluated second primary cancer risks among 717,335 women diagnosed with first primary breast cancer (aged 20-84 years and survived ≥1-year) in the SEER registries using standardized incidence ratios (SIRs; observed/expected). SIRs were estimated by race and ethnicity compared with the racial- and ethnic-matched general population, and further stratified by clinical characteristics of the index breast cancer. Poisson regression was used to test for heterogeneity by race and ethnicity. SIRs for second primary cancer differed by race and ethnicity with the highest risks observed among non-Hispanic/Latina Asian American, Native Hawaiian, or other Pacific Islander (AANHPI), non-Hispanic/Latina Black (Black), and Hispanic/Latina (Latina) survivors and attenuated risk among non-Hispanic/Latina White (White) survivors (SIRAANHPI = 1.49, 95% CI = 1.44-1.54; SIRBlack = 1.41, 95% CI = 1.37-1.45; SIRLatina = 1.45, 95% CI = 1.41-1.49; SIRWhite = 1.09, 95% CI = 1.08-1.10; p-heterogeneity<.001). SIRs were particularly elevated among AANHPI, Black, and Latina survivors diagnosed with an index breast cancer before age 50 (SIRs range = 1.88-2.19) or with estrogen receptor-negative tumors (SIRs range = 1.60-1.94). Heterogeneity by race and ethnicity was observed for 16/27 site-specific second cancers (all p-heterogeneity's < .05) with markedly elevated risks among AANHPI, Black, and Latina survivors for acute myeloid and acute non-lymphocytic leukemia (SIRs range = 2.68-3.15) and cancers of the contralateral breast (SIRs range = 2.60-3.01) and salivary gland (SIRs range = 2.03-3.96). We observed striking racial and ethnic differences in second cancer risk among breast cancer survivors. Additional research is needed to inform targeted approaches for early detection strategies and treatment to reduce these racial and ethnic disparities.

Simulating the population impact of interventions to reduce racial gaps in breast cancer treatment. J Natl Cancer Inst 2024; 116:902-910. [PMID: 38281076 PMCID: PMC11160503 DOI: 10.1093/jnci/djae019] [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: 08/28/2023] [Revised: 01/16/2024] [Accepted: 01/21/2024] [Indexed: 01/29/2024] Open
Abstract
BACKGROUND Inequities in guideline-concordant treatment receipt contribute to worse survival in Black patients with breast cancer. Inequity-reduction interventions (eg, navigation, bias training, tracking dashboards) can close such treatment gaps. We simulated the population-level impact of statewide implementation of inequity-reduction interventions on racial breast cancer inequities in North Carolina. METHODS Using registry-linked multipayer claims data, we calculated inequities between Black and White patients receiving endocrine therapy (n = 12 033) and chemotherapy (n = 1819). We then built cohort-stratified (endocrine therapy and chemotherapy) and race-stratified Markov models to simulate the potential increase in the proportion of patients receiving endocrine therapy or chemotherapy and subsequent improvements in breast cancer outcomes if inequity-reducing intervention were implemented statewide. We report uncertainty bounds representing 95% of simulation results. RESULTS In total, 75.6% and 72.1% of Black patients received endocrine therapy and chemotherapy, respectively, over the 2006-2015 and 2004-2015 periods (vs 79.3% and 78.9% of White patients, respectively). Inequity-reduction interventions could increase endocrine therapy and chemotherapy receipt among Black patients to 89.9% (85.3%, 94.6%) and 85.7% (80.7%, 90.9%). Such interventions could also decrease 5-year and 10-year breast cancer mortality gaps from 3.4 to 3.2 (3.0, 3.3) and from 6.7 to 6.1 (5.9, 6.4) percentage points in the endocrine therapy cohorts and from 8.6 to 8.1 (7.7, 8.4) and from 8.2 to 7.8 (7.3, 8.1) percentage points in the chemotherapy cohorts. CONCLUSIONS Inequity-focused interventions could improve cancer outcomes for Black patients, but they would not fully close the racial breast cancer mortality gap. Addressing other inequities along the cancer continuum (eg, screening, pre- and postdiagnosis risk factors) is required to achieve full equity in breast cancer outcomes.

Barriers to endocrine therapy adherence: perspectives of Black breast cancer survivors and their providers. J Cancer Surviv 2024:10.1007/s11764-024-01574-7. [PMID: 38520598 DOI: 10.1007/s11764-024-01574-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 03/18/2024] [Indexed: 03/25/2024]
Abstract
PURPOSE Adherence to oral endocrine therapy (ET) remains an issue for up to half of women prescribed these medications. There is emerging data that Black breast cancer survivors (BCS) have lower rates of ET adherence. Given the disparities in breast cancer recurrence and survival for Black BCS compared to their White counterparts, the goal of this study is to better understand barriers to ET adherence among Black BCS from the patient and provider perspectives. METHODS In this qualitative study, we conducted semi-structured interviews between October 29, 2021, and March 1, 2023. Interviews were recorded and transcribed, and coded data were organized into primary and secondary themes. Participants were recruited from a single academic cancer center. A convenience sample of 24 Black BCS and 9 medical oncology providers was included. Eligible BCS were 18 years or older, English-speaking, diagnosed with stage I-III hormone receptor-positive breast cancer, who had initiated ET. RESULTS Mean age of the BCS was 55 years (interquartile range, IQR 17 years). About one-fourth had a high school diploma or less (26.1%) and 47% completed a college education or higher. Approximately one-third of participants had annual household incomes of $40,000 or less (30.4%) or more than $100,000 (30.4%). Forty-three percent of the patient participants had private insurance; 11% were insured through Medicaid or the federal healthcare exchange; 26.1% had Medicare; and 13% were uninsured. Of the 9 medical oncology providers interviewed, 2 were advanced practice providers, and 7 were medical oncologists. We found 3 major themes: (1) Black BCS often had concerns about ET before initiation; (2) after initiation, both BCS and providers reported side effects as the most impactful barrier to ET adherence; and (3) survivors experienced challenges with managing ET side effects. CONCLUSIONS Our results suggest that multifaceted support interventions for managing ET-related symptoms may lead to improved adherence to ET among Black women and may reduce disparities in outcomes. IMPLICATIONS FOR CANCER SURVIVORS Multifaceted support interventions for managing ET-related symptoms may lead to improved adherence to ET among Black breast cancer survivors.

Abstract
BACKGROUND The review aimed to investigate geographic and sociodemographic factors associated with receipt of systemic anticancer therapies (SACT) for women with secondary (metastatic) breast cancer (SBC). METHODS Included studies reported geographic and sociodemographic factors associated with receipt of treatment with SACT for women > 18 years with an SBC diagnosis. Information sources searched were Ovid CINAHL, Ovid MEDLINE, Ovid Embase and Ovid PsychINFO. Assessment of methodological quality was undertaken using the Joanna Briggs Institute method. Findings were synthesised using a narrative synthesis approach. RESULTS Nineteen studies published between 2009 and 2023 were included in the review. Overall methodological quality was assessed as low to moderate. Outcomes were reported for treatment receipt and time to treatment. Overall treatment receipt ranged from 4% for immunotherapy treatment in one study to 83% for systemic anticancer therapies (unspecified). Time to treatment ranged from median 54 days to 95 days with 81% of patients who received treatment < 60 days. Younger women, women of White origin, and those women with a higher socioeconomic status had an increased likelihood of timely treatment receipt. Treatment receipt varied by geographical region, and place of care was associated with variation in timely receipt of treatment with women treated at teaching, research and private institutions being more likely to receive treatment in a timely manner. CONCLUSIONS Treatment receipt varied depending upon type of SACT. A number of factors were associated with treatment receipt. Barriers included older age, non-White race, lower socioeconomic status, significant comorbidities, hospital setting and geographical location. Findings should however be interpreted with caution given the limitations in overall methodological quality of included studies and significant heterogeneity in measures of exposure and outcome. Generalisability was limited due to included study populations. Findings have practical implications for the development and piloting of targeted interventions to address specific barriers in a socioculturally sensitive manner. Addressing geographical variation and place of care may require intervention at a commissioning policy level. Further qualitative research is required to understand the experience and of women and clinicians. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42020196490.

Abstract
PURPOSE Adjuvant endocrine therapy (AET) increases sexual health challenges for women with early-stage breast cancer. Black women are more likely than women of other racial/ethnic groups to report adverse symptoms and least likely to initiate and maintain AET. Little is known about how sexual health challenges influence patient-clinician communication and treatment adherence. This study explores facilitators of and barriers to patient-clinician communication about sexual health and how those factors might affect AET adherence among Black women with early-stage breast cancer. METHODS We conducted 32 semi-structured, in-depth interviews among Black women with early-stage breast cancer in the U.S. Mid-South region. Participants completed an online questionnaire prior to interviews. Data were analyzed using thematic analysis. RESULTS Participants' median age was 59 (range 40-78 years, SD = 9.0). Adverse sexual symptoms hindered participants' AET adherence. Facilitators of patient-clinician communication about sexual health included female clinicians and peer support. Barriers included perceptions of male oncologists' disinterest in Black women's sexual health, perceptions of male oncologists' biased beliefs about sexual activity among older Black women, cultural norms of sexual silence among Southern Black women, and medical mistrust. CONCLUSIONS Adverse sexual symptoms and poor patient-clinician communication about sexual health contribute to lower AET adherence among Black women with early-stage breast cancer. New interventions using peer support models and female clinicians trained to discuss sexual health could ameliorate communication barriers and improve treatment adherence. IMPLICATIONS FOR CANCER SURVIVORS Black women with early-stage breast cancer in the U.S. Mid-South may require additional resources to address sociocultural and psychosocial implications of cancer survivorship to enable candid discussions with oncologists.

Abstract
BACKGROUND There are limited data examining racial disparities in locoregional recurrence (LRR) among women with access to high-quality care. We aimed to examine differences in late LRR by race in patients with stage I-IIIA, hormone receptor-positive (HR+) breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel (NSABP) B-42 trial. METHODS From 2006 to 2010, 3966 postmenopausal women with stage I-IIIA HR+ breast cancer who were disease-free after 5 years of endocrine therapy were randomized to an additional 5 years of endocrine therapy or placebo. Patients were excluded if multi-racial or if race was unknown. Kaplan-Meier curves were used to estimate 6-year LRR from the time of trial registration and according to race. Cox proportional hazards models were used for adjusted survival analyses. RESULTS Overall, 3929 NSABP B-42 patients were included: 3688 (93.9%) White, 151 (3.8%) Black, and 90 (2.3%) Asian patients. Median follow-up was 75.2 months. Overall estimated 6-year LRR from trial registration was 1.8% and differed by race: LRR rates were 1.7% in White women, 4.9% in Black women, and 0% in Asian women (p = 0.046). Adjusted Cox proportional hazards analysis found Black race to be independently associated with LRR (hazard ratio [HzR] 2.36, 95% confidence interval [CI] 1.01-5.49; p = 0.047). Node-positivity was also associated with increased LRR (HzR 1.75, 95% CI 1.07-2.86; p = 0.025). Adjusted Cox analysis found LRR (HzR 2.32, 95% CI 1.33-4.06; p = 0.003) to be associated with increased overall mortality; however, race was not independently associated with mortality. CONCLUSION Among postmenopausal patients with stage I-IIIA HR+ breast cancer in the NSABP B-42 trial, racial differences in late LRR were present, with the highest LRR in Black women.

Abstract
INTRODUCTION Racial disparities in breast cancer treatment contribute to Black women having the worst breast cancer survival rates in the U.S. We investigated whether differences in receipt of optimal locoregional treatment (OLT), defined as receipt of mastectomy, breast-conserving surgery, or no surgery when contraindicated, existed between Black and White women with early-stage breast cancer from 2008-2018. METHODS In this retrospective cohort study, data from the Surveillance, Epidemiology, and End Results (SEER) Program Incidence Database was utilized to identify tumor cases from Black and White women aged 20-64 years old with stage I-II breast cancer. Logistic regression analyses were used to evaluate the associations between race and receipt of OLT as well as potential effect modification by tumor characteristics, and year of diagnosis. RESULTS Among 177,234 women diagnosed with early-stage breast tumors, disparities in OLT between Black and White women were present from 2008-2010 (2008: 82.1% Black vs. 85.7% White, p<0.001; 2009: 82.1% Black vs. 85.8% White, p<0.001; 2010: 82.2% Black vs. 87.2% White, p<0.001). This disparity was eliminated between 2010-2011 (86.3% Black vs. 87.5% White, p = 0.15), and did not reoccur during the remainder of the study period. From 2010-2011, more Black women received radiation therapy following breast-conserving surgery (43.4% to 48.9%; p = 0.001), which accounted for an overall increased receipt of OLT. CONCLUSION Increased receipt of radiation therapy with breast-conserving surgery appeared to drive a substantial increase in OLT for Black women from 2010-2011 that lasted throughout the study period. Further research on the underlying mechanisms that reduced this disparity is warranted.

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.

Racial and Ethnic Disparities in Locoregional Recurrence Among Patients With Hormone Receptor-Positive, Node-Negative Breast Cancer: A Post Hoc Analysis of the TAILORx Randomized Clinical Trial. JAMA Surg 2023; 158:583-591. [PMID: 37043210 PMCID: PMC10099173 DOI: 10.1001/jamasurg.2023.0297] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 12/04/2022] [Indexed: 04/13/2023]
Abstract
Importance Whether racial and ethnic disparities in locoregional recurrence (LRR) exist among patients with similar access to care treated in randomized clinical trials is unknown. Objective To examine racial and ethnic differences in LRR among patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (ERBB2 [formerly HER2 or HER2/neu])-negative, node-negative breast cancer enrolled in the Trial Assigning Individualized Options for Treatment (TAILORx). Design, Setting, and Participants This unplanned retrospective post hoc analysis examined a prospective multicenter clinical trial population of women with breast cancer enrolled between 2006 and 2010, with 9 years of follow-up. The TAILORx investigators randomized patients to treatment based on their Oncotype DX recurrence score, including endocrine therapy alone (recurrence score <11), endocrine therapy alone vs chemotherapy followed by endocrine therapy (recurrence score 11-25), or chemotherapy followed by endocrine therapy (recurrence score >25). Patients with unknown race and ethnicity or lack of follow-up were excluded from this analysis. Data analysis was performed between December 2021 and March 2022. Main Outcome and Measures Locoregional recurrence was defined as ipsilateral in breast, skin, chest wall, or regional nodal recurrence without concurrent distant recurrence, and was stratified by racial and ethnic group. Unadjusted Kaplan-Meier and adjusted Cox proportional hazards regression models were used for survival analyses. Results Of the 10 273 women enrolled in TAILORx, this analysis included 9369 with T1-2N0 HR-positive, ERBB2-negative breast cancer. Of these patients, 428 (4.6%) were Asian, 886 (9.4%) were Hispanic, 676 (7.2%) were non-Hispanic Black (hereinafter Black), and 7406 (78.8%) were non-Hispanic White (hereinafter White). Assigned treatment receipt was high, with a 9.3% (n = 870) crossover of treatment groups and a median endocrine therapy duration of longer than 60 months, ranging from 61.1 to 65.9 months, across racial and ethnic groups. A total of 6818 patients (72.6%) received radiation (6474 [96.1%] after breast-conserving surgery and 344 [13.0%] after mastectomy). At a median follow-up of 94.8 months (range, 1-138 months), 8-year LRR rates were 3.6% (95% CI, 1.6%-5.6%) in Asian patients, 3.9% (95% CI, 2.2%-5.4%) in Black patients, 3.1% in Hispanic patients (95% CI, 1.7%-4.5%), and 1.8% (95% CI, 1.5%-2.3%) in White patients (P < .001). In survival analyses adjusted for patient, tumor, and treatment factors, Asian race (hazard ratio, 1.91 [95% CI, 1.12-3.29]) and Black race (1.78 [1.15-2.77]) were independently associated with LRR. In adjusted survival analyses for breast cancer mortality, LRR was independently associated with increased breast cancer mortality (hazard ratio, 5.71 [95% CI, 3.50-9.31]). Conclusions and Relevance In this post hoc analysis, racial and ethnic differences in LRR were observed among patients with T1-2N0 HR-positive, ERBB2-negative breast cancer despite high rates of treatment receipt in this clinical trial population, with the highest LRR rates in Asian and Black patients. Further study is needed to understand whether failure to rescue after LRR may contribute to racial disparities in breast cancer mortality.

[PMID: 37046634 PMCID: PMC10093612 DOI: 10.3390/cancers15071973] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 03/09/2023] [Accepted: 03/15/2023] [Indexed: 03/29/2023] Open
Abstract
Background: Oral endocrine therapy (ET) is an inexpensive and effective therapy for hormone receptor-positive (HR+) breast cancer that prevents recurrence but relies upon long-term adherence for up to ten years. More than 80% of breast cancer patients have an HR+ phenotype and are candidates for ET, but approximately half discontinue or become non-adherent by five years. ET underuse is more prevalent in Black and young (<50 yrs) women, which may contribute to outcome disparities in these groups. The objective of this study was to evaluate the feasibility, acceptability, and utility of a patient-centered counseling intervention to enhance ET adherence, with a focus on the needs of Black and younger women. Methods: We conducted a single-arm pilot study of a twelve-month motivational interviewing (MI) intervention consisting of five MI counseling sessions, an interactive workbook, a resource guide, and an educational video developed and revised with iterative patient and clinician input. The eligible participants were >18 years old, English speaking, and with stage I–III HR+ breast cancer. Participants were recruited across a large academic medical center and four community sites. Feasibility and acceptability were assessed by measures of participant recruitment, retention, session participation, and patient-reported satisfaction. ET adherence at 12 months was assessed by self-report and medication event monitoring system (MEMS) caps using a continuous measure of the proportion of days covered (PDC) as well as a dichotomous measure of the optimal adherence, defined as >80% PDC. Results: Forty-two women initiated the intervention, of whom thirty-five participants (83%) completed outcome assessments at 12 months, including thirteen Black and twenty-two non-Black participants. The average participant age was 54.8 years (range: 25–73). Overall, 97% completed at least three MI sessions and 83% completed at least four sessions. Participant retention and satisfaction were high, particularly among Black women. Self-reported adherence at 12 months was 88% overall (100% in Black women and 81% in non-Black women). The majority of women also achieved 80% of days adherent using MEMS caps, with a greater adherence in Black women. Conclusions: This study demonstrates the feasibility, acceptability, and early promise of the effectiveness of an MI counseling-based intervention to promote ET adherence and prevent breast cancer recurrence in diverse populations.

Abstract
PURPOSE Characterizing oral adjuvant endocrine therapy (ET) non-initiation and non-persistence in young women with breast cancer can inform strategies to improve overall adherence in this population. METHODS We identified 693 women with hormone receptor-positive, stage I-III breast cancer enrolled in a cohort of women diagnosed with breast cancer at age ≤ 40 years. Women were classified as non-initiators if they did not report taking ET in the 18 months after diagnosis. Women who initiated but did not report taking ET subsequently (through 5-year post-diagnosis) were categorized as non-persistent. We assessed ET decision-making and used logistic regression to identify factors associated with non-initiation/non-persistence and to evaluate the association between non-persistence and recurrence. RESULTS By 18 months, 9% had not initiated ET. Black women had higher odds and women with a college degree had lower odds of non-initiation. Among 607 women who initiated, 20% were non-persistent. Younger age, being married/partnered, and reporting more weight problems were associated with higher odds of non-persistence; receipt of chemotherapy and greater hot flash and vaginal symptom burden were associated with lower odds of non-persistence. Adjusting for age and clinical characteristics, non-persistence was associated with lower odds of recurrence. Women who initiated were more likely to report shared decision-making than non-initiators (57% vs. 38%, p = 0.049), while women who were non-persistent were less likely to indicate high confidence with the decision than women who were persistent (40% vs. 63%, p < 0.001). CONCLUSION Interventions to improve ET decision-making may facilitate initiation and address barriers to adherence in young breast cancer survivors. TRIAL REGISTRATION www.

Abstract
Purpose of Review Breast cancer is the most commonly diagnosed cancer in women, and the leading cause of cancer death. However, racial and ethnic minority groups, as well as rural and underserved populations, face disparities that limit their access to specialty care for breast cancer. To address these disparities, health care providers can leverage an electronic health record (EHR). Recent Findings Few studies have evaluated the potential benefits of using EHRs to address breast cancer disparities, and none of them outlines a standard approach for this effort. However, these studies outline that EHRs can be used to identify and notify patients at risk for breast cancer. These systems can also automate referrals and scheduling for screening and genetic testing, as well as recruit eligible patients for clinical trials. EHRs can also provide educational materials to reduce risks associated with modifiable risk factors, such as physical activity, obesity, and smoking. These systems can also support telemedicine visits and centralize inter-institutional communication to improve treatment adherence and the quality of care. Summary EHRs have tremendous potential to increase accessibility and communication for patients with breast cancer by augmenting patient engagement, improving communication between patients and providers, and strengthening communication among providers. These efforts can reduce breast cancer disparities by increasing breast cancer screening, improving treatment adherence, expanding access to specialty care, and promoting risk-reducing habits among racial and ethnic minority groups and other underserved populations.
