Implementing motivational interviewing to improve endocrine therapy adherence among breast cancer patients: a qualitative process evaluation of the getset pilot intervention.

Background: This study evaluates the implementation of the GETSET (Guiding Endocrine Therapy Success through Empowerment and Teamwork) pilot, a motivational interviewing (MI) intervention aimed at improving endocrine therapy (ET) adherence among patients with breast cancer.

Methods: Using the Consolidated Framework for Implementation Research (CFIR), qualitative interviews were conducted with site staff (N = 2), patients (N = 4), and counselors (N = 2).

Results: The thematic analysis identified facilitators such as high-quality materials, ease of scheduling sessions, and effective communication among staff.

Optimizing Postneoadjuvant Treatment of Residual Breast Cancer With Adjuvant Bevacizumab Alone, With Metronomic or Standard-Dose Chemotherapy: A Combined Analysis of DFCI 05-055 and DFCI 09-134/TBCRC 012/ABCDE Clinical Trials.

Background: Breast cancer patients with residual disease after neoadjuvant therapy have increased risk of recurrence. Novel therapies to decrease this risk are urgently needed.

Methods: Two clinical trials (05-055 and 09-134) offered adjuvant bevacizumab-based therapy to stage I-III breast cancer patients with residual disease after neoadjuvant chemotherapy.

Quality of Life Outcomes in Breast Cancer Patients Receiving Chemotherapy With or Without Radiation Therapy.

Purpose: Understanding quality of life (QOL) implications of individual components of breast cancer treatment is important as systemic therapies continue to improve oncologic outcomes. We hypothesized that adjuvant radiation therapy does not significantly impact QOL domains in breast cancer patients undergoing chemotherapy.

Methods: Data was drawn from three prospective studies in women with localized breast cancer being treated with chemotherapy from March 2014 to December 2019.

Cancer information and population health resource: a resource for catchment area data and cancer outcomes research.

Background: The University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center has developed a novel data resource, the Cancer Information and Population Health Resource (CIPHR), for conducting catchment area evaluation and cancer population health research that links the North Carolina Central Cancer Registry (NCCCR) to medical and pharmacy claims data from Medicare, Medicaid, and private plans operating within North Carolina. This study's aim was to describe the CIPHR data and provide examples of potential cohorts available in those data.

Methods: We present the underlying populations included in the NCCCR and claims data before linkage and demonstrate estimated sample sizes when these data are linked and commonly used insurance enrollment criteria are applied.

Structural Racism and Treatment Delay Among Black and White Patients With Breast Cancer.

Purpose: Structural racism (SR) is a potential driver of health disparities, but research quantifying its impacts on cancer outcomes has been limited. We aimed to develop a multidimensional county-level SR measure and to examine the association of SR with breast cancer (BC) treatment delays among Black and White patients.

Methods: The cohort included 32,095 individuals from the North Carolina Central Cancer Registry with stage I to III BC diagnosed between 2004 and 2017 and linked to multipayer insurance claims from the Cancer Information and Population Health Resource.

Differences in 21-Gene and PAM50 Recurrence Scores in Younger and Black Women With Breast Cancer.

Purpose: Genomic tests, such as the Oncotype Dx 21-gene and Prosigna risk of recurrence (ROR-P) assay, are commonly used for breast cancer prognostication. Emerging data suggest variability between assays, but this has not been compared in diverse populations.

Materials And Methods: RNA sequencing was performed on 647 previously untreated stage I-III estrogen receptor-positive/human epidermal growth factor receptor 2-negative tumors in the Carolina Breast Cancer Study, which oversampled Black and younger women (age <50 years at diagnosis), using research versions of two common RNA-based prognostic assays: ROR-P and the 21-gene recurrence score (RS).

Sticking to the script: Breast cancer patients' decision making regarding oral endocrine therapy.

Objectives: We sought to understand why some women with early-stage breast cancer decide to forgo or discontinue endocrine therapy (ET), and to identify factors that might lead to greater acceptance of, and long-term adherence to, this treatment.

Methods: We conducted in-depth interviews with N = 53 stage I-III HR+ women who were either non-initiators of ET, initiators who discontinued or initiators who continued with variable daily patterns of adherence. An inductive content analysis was performed to explore the decision-making process of women prescribed ET.

Emotional and functional well-being in long-term breast cancer survivorship.

Purpose: Emotional and functional well-being (EWB and FWB) are important components of mental health and quality of life. This study aims to evaluate long-term EWB and FWB in breast cancer (BC) survivors.

Methods: The Carolina Breast Cancer Study Phase 3 oversampled Black and younger (< 50 years in age) women so that they each represent approximately 50% of the study population and assessed participants' EWB and FWB with the Functional Assessment of Cancer Therapy-Breast (FACT-B) at 5- (baseline), 25-, and 84-months post diagnosis.

Financial burden among metastatic breast cancer patients: a qualitative inquiry of costs, financial assistance, health insurance, and financial coping behaviors.

Purpose: Metastatic breast cancer (MBC) patients often face substantial financial burden due to prolonged and expensive therapy. However, in-depth experiences of financial burden among MBC patients are not well understood.

Methods: Qualitative interviews were conducted to describe the experiences of financial burden for MBC patients, focusing on the drivers of financial burden, their experience using their health insurance, accessing financial assistance, and any resulting cost-coping behaviors.

Functional Status Associations With Treatment Receipt and Outcomes Among Older Adults Newly Diagnosed With Multiple Myeloma.

Purpose: Multiple myeloma (MM) is a prevalent hematologic malignancy in older adults, who often experience physical disability, increased health care usage, and reduced treatment tolerance. Home health (HH) services are frequently used by this group, but the relationship between disability, HH use, and MM treatment receipt is unclear. This study examines the connections between disability, treatment receipt, and survival outcomes in older adults with newly diagnosed MM using a nationwide data set.

Simulating the population impact of interventions to reduce racial gaps in breast cancer treatment.

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.

Disparities in OncotypeDx Testing and Subsequent Chemotherapy Receipt by Geography and Socioeconomic Status.

Background: OncotypeDx is a prognostic and predictive genomic assay used in early-stage hormone receptor-positive, HER2- (HR+/HER2-) breast cancer. It is used to inform adjuvant chemotherapy decisions, but not all eligible women receive testing. We aimed to assess variation in testing by demographics and geography, and to determine whether testing was associated with chemotherapy.

Patterns of chemotherapy receipt among patients with hormone receptor-positive, HER2-negative breast cancer.

Background: Breast cancer chemotherapy utilization not only may differ by race and age, but also varies by genomic risk, tumor characteristics, and patient characteristics. Studies in demographically diverse populations with both clinical and genomic data are necessary to understand potential disparities by race and age.

Methods: In the Carolina Breast Cancer Study Phase 3 (2008-2013), chemotherapy receipt (yes/no) and regimen type were assessed in association with age and race among hormone receptor (HR) positive and HER2-negative tumors (n = 1862).

Characteristics, healthcare utilization, and outcomes of patients with HER2-low breast cancer.

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.

Knowledge, Attitudes, and Resources of Frontline Oncology Support Personnel Regarding Financial Burden in Patients With Cancer.

Purpose: Financial navigation services support patients with cancer and address the direct and indirect financial burden of cancer diagnosis and treatment. These services are commonly delivered through a variety of frontline oncology support personnel (FOSP) including navigators, social workers, supportive care providers, and other clinic staff, but the perspective of FOSPs is largely absent from current literature on financial burden in oncology. We surveyed a national sample of FOSPs to understand their perspectives on patient financial burden, resource availability, and barriers and facilitators to assisting patients with cancer-related financial burden.

Multidimensional financial hardship among uninsured and insured young adult patients with metastatic breast cancer.

Background: Little is known about the heterogeneous nature of financial hardship in younger patients with metastatic disease and the extent to which insurance protects against it. We examine the association between insurance status and multidimensional indicators of financial hardship in a national sample of women with metastatic breast cancer.

Methods: We conducted a national, retrospective online survey in partnership with the Metastatic Breast Cancer Network.

Motivational Interviewing Counseling to Increase Endocrine Therapy Adherence in Diverse Patients.

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.

Risk Factors for Return to the Emergency Department and Readmission in Patients With Hospital-Diagnosed Advanced Lung Cancer.

Background: Advanced lung cancer (ALC) is a symptomatic disease often diagnosed in the context of hospitalization. The index hospitalization may be a window of opportunity to improve care delivery.

Objectives: We examined the patterns of care and risk factors for subsequent acute care utilization among patients with hospital-diagnosed ALC.

Race, geography, and risk of breast cancer treatment delays: A population-based study 2004-2015.

Background: Treatment delays affect breast cancer survival and constitute poor-quality care. Black patients experience more treatment delay, but the relationship of geography to these disparities is poorly understood.

Methods: We studied a population-based, retrospective, observational cohort of patients with breast cancer in North Carolina between 2004 and 2017 from the Cancer Information and Population Health Resource, which links cancer registry and sociodemographic data to multipayer insurance claims.

A phase II single-arm trial of memantine for prevention of cognitive decline during chemotherapy in patients with early breast cancer: Feasibility, tolerability, acceptability, and preliminary effects.

Background: Cognitive difficulties have been described after chemotherapy for breast cancer, but there is no standard of care to improve cognitive outcomes in these patients. This trial examined the feasibility, tolerability, acceptability, and preliminary effects of memantine to prevent cognitive decline during chemotherapy for breast cancer.

Methods: Patients with stage I-III breast cancer, scheduled for neo/adjuvant chemotherapy, completed a cognitive battery prior to and 4 weeks after completing chemotherapy.

Lessening the Impact of Financial Toxicity (LIFT): a protocol for a multi-site, single-arm trial examining the effect of financial navigation on financial toxicity in adult patients with cancer in rural and non-rural settings.

Background: Almost half of the patients with cancer report cancer-related financial hardship, termed "financial toxicity" (FT), which affects health-related quality of life, care retention, and, in extreme cases, mortality. This increasingly prevalent hardship warrants urgent intervention. Financial navigation (FN) targets FT by systematically identifying patients at high risk, assessing eligibility for existing resources, clarifying treatment cost expectations, and working with patients and caregivers to develop a plan to cope with cancer costs.

Cost-Effectiveness of Pharmacologic Treatment Options for Women With Endocrine-Refractory or Triple-Negative Metastatic Breast Cancer.

Purpose: Treatments for endocrine-refractory or triple-negative metastatic breast cancer (mBC) are modestly effective at prolonging life and improving quality of life but can be extremely expensive. Given these tradeoffs in quality of life and cost, the optimal choice of treatment sequencing is unclear. Cost-effectiveness analysis can explicitly quantify such tradeoffs, enabling more informed decision making.
