Abstract
PURPOSE We sought to assess survival outcomes of patients with de novo metastatic breast cancer (dnMBC) who did not receive treatment irrespective of the reason. METHODS Adults with dnMBC were selected from the NCDB (2010-2016) and stratified based on receipt of treatment (treated = received at least one treatment and untreated = received no treatments). Overall survival (OS) was estimated using the Kaplan-Meier method, and groups were compared. Cox proportional hazards models were used to identify factors associated with OS. RESULTS Of the 53,240 patients with dnMBC, 92.1% received at least one treatment (treated), and 7.9% had no documented treatments, irrespective of the reason (untreated). Untreated patients were more likely to be older (median 68 y vs 61 y, p < 0.001), have higher comorbidity scores (p < 0.001), have triple-negative disease (17.8% vs 12.6%), and a higher disease burden (≥ 2 metastatic sites: 38.2% untreated vs 29.2% treated, p < 0.001). The median unadjusted OS in the untreated subgroup was 2.5 mo versus 36.4 mo in the treated subgroup (p < 0.001). After adjustment, variables associated with a worse OS in the untreated cohort included older age, higher comorbidity scores, higher tumor grade, and triple-negative (vs HR + /HER2-) subtype (all p < 0.05), while the number of metastatic sites was not associated with survival. CONCLUSIONS Patients with dnMBC who do not receive treatment are more likely to be older, present with comorbid conditions, and have clinically aggressive disease. Similar to those who do receive treatment, survival in an untreated population is associated with select patient and disease characteristics. However, the prognosis for untreated dnMBC is dismal.

Abstract
INTRODUCTION With the increasing utilization of genomic assays, such as the Oncotype DX recurrence score (RS), the relevance of anatomic staging has been questioned for select older patients with breast cancer. We sought to evaluate differences in chemotherapy receipt and/or survival among older patients based on RS and sentinel lymph node biopsy (SLNB) receipt/result. METHODS Patients aged ≥ 65 diagnosed with pT1-2/cN0/M0 hormone-receptor-positive (HR+)/HER2-breast cancer (2010-2019) were selected from the National Cancer Database. Logistic regression was used to identify factors associated with chemotherapy receipt. Cox proportional hazards models were used to estimate the association of RS/SLNB group with overall survival. A cost-benefit study was also performed. RESULTS Of the 75,428 patients included, the majority had an intermediate RS (58.2% versus 27.9% low, 13.8% high) and were SLNB- (85.1% versus 11.6% SLNB+, 3.3% none). Chemotherapy was recommended for 13,442 patients (17.8%). After adjustment, chemotherapy receipt was more likely with higher RS and SLNB+. After adjustment, SLNB receipt/result was only associated with overall survival among those with an intermediate RS. However, returning to the OR for SLNB is not cost-effective. CONCLUSIONS SLNB receipt/result was associated with survival for those with an intermediate RS, but not a low or high RS, suggesting that an SLNB may indeed be unnecessary for select older patients with breast cancer.

Abstract
Background: Breast cancer is the most common cancer in women, and older patients comprise an increasing proportion of patients with this disease. The older breast cancer population is heterogenous with unique factors affecting clinical decision making. While many models have been developed and tested for breast cancer patients of all ages, tools specifically developed for older patients with breast cancer have not been recently reviewed. We systematically reviewed prognostic models developed and/or validated for older patients with breast cancer. Methods: We conducted a systematic search in 3 electronic databases. We identified original studies that were published prior to 8 November 2022 and presented the development and/or validation of models based mainly on clinico-pathological factors to predict response to treatment, recurrence, and/or mortality in older patients with breast cancer. The PROBAST was used to assess the ROB and applicability of each included tool. Results: We screened titles and abstracts of 7316 records. This generated 126 studies for a full text review. We identified 17 eligible articles, all of which presented tool development. The models were developed between 1996 and 2022, mostly using national registry data. The prognostic models were mainly developed in the United States (n = 7; 41%). For the derivation cohorts, the median sample size was 213 (interquartile range, 81-845). For the 17 included modes, the median number of predictive factors was 7 (4.5-10). Conclusions: There have been several studies focused on developing prognostic tools specifically for older patients with breast cancer, and the predictions made by these tools vary widely to include response to treatment, recurrence, and mortality. While external validation was rare, we found that it was typically concordant with interval validation results. Studies that were not validated or only internally validated still require external validation. However, most of the models presented in this review represent promising tools for clinical application in the care of older patients with breast cancer.

Abstract
Abstract
Background During the COVID pandemic, we designed and implemented a program, called BQual-D, to maintain high quality care for patients with HR+, HER2 negative MBC who were taking oral anti-cancer therapy and needed to shelter at home. This program augmented available clinical resources with (1) trained nurse coaches to manage side effects, improve adherence, monitor for cancer progression and screen for psychological distress via telehealth, and (2) a care coordinator to arrange blood testing at local labs to facilitate timely medication dose adjustments. BQual-D served patients from August 2020 through April 2021. Here, we describe survey results assessing patient (pt) satisfaction with BQual-D. Methods Pt’s satisfaction surveys included questions rated on a Likert scale (1 “strongly disagree” to 5 “strongly agree”) with questions regarding the following: satisfaction with the quality of the nurse coaching calls; perception that the nurse coach listened to what they were trying to convey; whether or not their needs were met by the nurse coaching calls; whether they felt that they received adequate explanation regarding the nurse coaching calls; whether they would recommend the nurse coaching calls to a friend; perception of whether or not the nurse coach was negative or critical towards them; whether or not they would do it over (i.e., if they would return to the nurse coaching calls); whether or not they felt that the nurse coach was friendly or warm toward them; they were able to more effectively deal with care and symptoms; they felt free to express themselves; they were able to focus on what was of real concern to them; the nurse seemed to understand what they were thinking and feeling. Patients were also asked how much the calls helped with their care and symptoms. Descriptive statistics are reported (i.e., frequencies and means). Results 84 pts were screened and contacted for the BQual-D program. Of the 64 pts who responded, 52 (81.3%) were interested and enrolled in BQual-D; 12 (18.8%) declined. Among those who enrolled, 1 voluntarily withdrew, and 7 withdrew due to change in treatment. Participants had a mean age of 65 (range 36 – 88 yrs) and the following racial distribution - Caucasian/White (38, 73.1%), Black or African American (12, 23.1%), American Indian (1, 1.9%) and American Indian or Alaskan Native (1, 1.9%). Satisfaction surveys were received from 32 (50%) pts. Results of surveys regarding patient satisfaction with the nurse coach were generally positive. Pts agreed or strongly agreed that they were satisfied with the quality of the nurse coaching calls (94%), the nurse coach listened to what they were trying to convey (94%), their needs were met by the nurse coaching calls (91%), they understood the purpose of the call (90%), and they would recommend the nurse coaching calls to a friend (88%). The majority (74%) agreed or strongly agreed that they were able to more effectively deal with their care and symptoms after the nurse coach calls. When asked how much the calls helped their care and symptoms, 61% indicated that they made things a lot better, 19% indicated that they made things somewhat better, 16% indicated that they made no difference. One patient indicated that the calls made things somewhat worse. Conclusions During the COVID pandemic, when sheltering at home was encouraged, patient satisfaction with BQual-D, which provided additional health resources (nurse coaches, care coordinator) to support pts on oral therapy for HR+ MBC, was high. Resources needed to implement BQual-D should be explored as a way of providing additional support for pts to minimize the requirement for in-person visits. Funding: Supported by a grant from Pfizer.

Abstract
As part of ongoing efforts to meaningfully improve recruitment, enrollment, and accrual of older adults into cancer clinical trials, the National Cancer Institute (NCI) sponsored a workshop with experts across the country entitled Engaging Older Adults in the NCI Clinical Trials Network: Challenges and Opportunities. Three working groups, including Study Design, Infrastructure, and Stakeholders, were formed, who worked together to offer synergistic improvements in the system. Here, we summarize the workshop discussions of the Infrastructure Working Group, whose goal was to address infrastructural challenges, identify underlying resources, and offer solutions to facilitate accrual of older adults into cancer clinical trials. Based on preconference work and workshop discussions, four key recommendations to strengthen NCI infrastructure were proposed: 1) further centralize resources and expertise; 2) provide training for clinical research staff; (3) develop common data elements; and 4) evaluate what works and does not work. These recommendations provide a strategy to improve the infrastructure to enroll more older adults in cancer clinical trials.

Abstract
OBJECTIVE We aim to identify prognostic groups within a de novo metastatic cohort, incorporating both anatomic and biologic factors. BACKGROUND Staging for breast cancer now includes anatomic and biologic factors, although the guidelines for stage IV disease do not account for how these factors may influence outcomes. METHODS Adults with de novo metastatic breast cancer were selected from the National Cancer DataBase (2010-2013). Recursive partitioning analysis was used to group patients with similar overall survival (OS) based on clinical T/N stage, tumor grade, ER, PR, HER2, number of metastatic sites, and presence of bone-only metastases. Categories were created by amalgamating homogeneous groups based on 3-year OS rates (stage IVA: >50%, stage IVB: 30%-50%, stage IVC: <30%). RESULTS 16,187 patients were identified; median follow-up was 32 months. 65.2% had 1 site of distant metastasis, and 42.9% had bone-only metastases. Recursive partitioning analysis identified the number of metastatic sites (1 vs >1) as the first stratification point, and ER status as the second stratification point for both resulting groups. Additional divisions were made based on HER2 status, PR status, cT stage, tumor grade, and presence of bone-only metastases. After bootstrapping, significant differences in 3-year OS were noted between the 3 groups [stage IVB vs IVA: HR 1.58 (95% confidence interval 1.50-1.67), stage IVC vs IVA: HR 3.54 (95% confidence interval 3.33-3.77)]. CONCLUSIONS Both anatomic and biologic factors yielded reliable and reproducible prognostic estimates among patients with metastatic disease. These findings support formal stratification of de novo stage IV breast cancer into 3 distinct prognosis groups.

Abstract
Background: During the COVID pandemic, we designed and implemented a program, called BQual-D, to maintain high quality care for patients with HR+, HER2 negative MBC who were taking oral anti-cancer therapy and needed to shelter at home. This program augmented available clinical resources with (1) trained nurse coaches to manage side effects, improve adherence, monitor for cancer progression and screen for psychological distress via telehealth, and (2) a care coordinator to arrange blood testing at local labs to facilitate timely medication dose adjustments. BQual-D served patients from August, 2020 through April of 2021. Here, we describe survey results assessing provider satisfaction with BQual-D. Methods: Surveys assessing provider satisfaction were distributed in December, 2020 (Survey#1) and in April, 2021 (Survey#2). Provider demographics were collected with Survey#1. Eight questions assessed satisfaction with different aspects of the BQual-D program, including content of the nurse coach notes, communication with the program, timeliness of communication, frequency of notes, ease of reading the notes, ease of referring patients, and turnaround time for labs, which were rated on a Likert scale of 1 (strongly dissatisfied) to 10 (strongly satisfied), with an additional response choice of 0 (unable to assess). Providers were also asked if BQual-D led to changes in patient management (yes/no), the degree to which BQual-D supported the medical management of the patient (from 1=not at all to 7=significantly), the influence of BQual-D on patient wellbeing (positive effects, no change, negative effects), and the overall quality of care delivered by the program (from 1=excellent to 4=poor). Finally, we asked providers if they would continue to recommend their patients to BQual-D (yes, in the same way as the program has been deployed; yes but with improvements; or no). Results are described by frequencies and means. Results: Nineteen providers responded to Survey#1. Providers were physicians (31.6%), advanced practice providers (31.6%), nurses (31.6%) and a clinical pharmacist (5.3%). Respondents were 89.5% female, 94.7% White, and had a mean age of 44 years and mean 11 years in practice. Providers rated the quality of care provided by the BQual-D program as excellent (44%) or good (57%), all providers surveyed indicated that they would continue to recommend the program to patients, and 95% of providers indicated that the program had a positive effect on patients’ well-being. Half of the respondents indicated that BQual-D resulted in changes in or addition to patient management and 90% indicated that BQual-D significantly supported medical management. Providers were strongly satisfied (scores of 8-10 on the Likert scale) with overall communication with the BQual-D team (74%) and timeliness of communications (79%). Providers were also strongly satisfied with the content (68.4%), frequency (74%), and ease of reading (68%) program notes. Seven providers completed Survey#2, in which providers rated the overall quality of the program as excellent (57%) or good (43%); 86% indicated that they would continue to recommend the program to patients, and 86% indicated that the program had a positive effect on patients’ well-being. Conclusions: During the COVID pandemic, when sheltering at home was encouraged, provider satisfaction with BQual-D, which provided additional health resources (nurse coaches, care coordinator) to support patients on oral therapy for HR+ MBC, was high. Resources needed to implement BQual-D should be explored as a way of providing additional support for patients and providers in order to minimize the requirement for in-person visits.

Abstract
PURPOSE HER2 mutations (HER2mut) induce endocrine resistance in estrogen receptor positive (ER+) breast cancer. EXPERIMENTAL DESIGN In this single arm multi-cohort phase II trial, we evaluated the efficacy of neratinib plus fulvestrant in patients with ER+/HER2mut, HER2-non-amplified metastatic breast cancer (MBC) in the fulvestrant-treated (n=24) or fulvestrant-naïve cohort (n=11). Patients with ER-negative/HER2mut MBC received neratinib monotherapy in an exploratory ER- cohort (n=5). RESULTS The clinical benefit rate (CBR: 95% CI) was 38% (18-62%), 30% (7-65%), and 25% (1-81%) in the fulvestrant-treated, fulvestrant-naïve, and ER- cohort, respectively. Adding trastuzumab at progression in 5 patients resulted in 3 partial responses and 1 stable disease {greater than or equal to}24 weeks. CBR appeared positively associated with lobular histology and negatively associated with HER2 L755 alterations. Acquired HER2mut were detected in 5 of 23 patients at progression. CONCLUSION Neratinib and fulvestrant is active for ER+/HER2mut MBC. Our data supports further evaluation of dual HER2 blockade for the treatment of HER2mut MBC.

Abstract
BACKGROUND Weight gain is common for breast cancer survivors and associated with disease progression, recurrence, and mortality. Traditional behavioral programs fail to address symptoms (i.e., pain, fatigue, distress) experienced by breast cancer survivors that may interfere with weight loss and fail to capitalize on the concordance in weight-related health behaviors of couples. This study aimed to develop and examine the feasibility and acceptability of a behavioral weight and symptom management intervention for breast cancer survivors and their intimate partners. MATERIALS AND METHODS Interviews were conducted with N=14 couples with overweight/obesity to develop the intervention. Intervention feasibility and acceptability were examined through a single-arm pilot trial (N=12 couples). Patterns of change in intervention targets were examined for survivors and partners. RESULTS Themes derived from interviews were used to develop the 12-session couple-based intervention, which included components from traditional behavioral weight management interventions, appetite awareness training, and cognitive and behavioral symptom management protocols. Couples also worked together to set goals, create plans for health behavior change, and adjust systemic and relationship barriers to weight loss. Examples were tailored to the experiences and symptom management needs of breast cancer survivors and partners. The intervention demonstrated feasibility (attrition: 8%; session completion: 88%) and acceptability (satisfaction). Survivors and partners experienced reductions in weight and improvements in physical activity, eating behaviors, emotional distress, and self-efficacy. Survivors evidenced improvements in fatigue and pain. CONCLUSIONS A behavioral weight and symptom management intervention for breast cancer survivors and partners is feasible, acceptable, and is potentially efficacious.

Abstract
Abstract
Introduction: The irreversible pan-HER inhibitor NER showed modest single agent activity for HER2mut MBC in Part I of MutHER trial. In Part II, we hypothesized that (1) N+F would improve activity in estrogen receptor positive (ER+) HER2mut MBC due to ER-HER2 crosstalk and (2) dual HER2 blockade by adding trastuzumab at disease progression (PD) could overcome resistance.
Methods: Pts with ER+HER2mut MBC were enrolled to 2 cohorts (FUL treated or naive) to receive N+F with diarrhea prophylaxis. ER- pts received NER in an exploratory ER- cohort. Trastuzumab was added at PD if approved by insurance. Simon's Minimax 2-stage phase II design with the primary endpoint of clinical benefit rate (CBR: rates of complete/partial response [CR/PR] plus stable disease [SD] >24 weeks [wks]), with anticipated vs null hypothesis being CBR of 55% vs 35% (FUL treated) or 65% vs 40% (FUL naïve) with 80% power, 1 sided 0.05 alpha, was used. Secondary endpoints included progression free survival (PFS) and adverse events (AEs). Serial blood samples were analyzed for circulating tumor DNA (ctDNA) by Guardant360 for concomitant mutations, HER2mut variant allele frequency (VAF) dynamics, and resistance mechanisms.
Results: Between Sep. 2015 and Oct. 2020, 40 pts with HER2mut MBC were enrolled, completing the 1st stage of each ER+ cohort. 35 pts (21 FUL treated, 10 FUL naïve, 4 ER-) were evaluable for response, with median age 63 (35-82) years, 3 (0-12) prior MBC regimen, lobular BC in 13 (37%) and visceral mets in 32 (91%) pts. 21 (68%) ER+ pts had prior CDK4/6 inhibitor. All but 1 pt has come off study due to PD. Table 1 shows the efficacy by cohort. Further enrollment is closed per protocol. Adding trastuzumab at PD induced CB in 4 (3 PR, 1 SD≥24 wks) of 5 pts (1 ER-, 4 ER+), with PFS 28 (95% CI 18~NA) wks. Common AEs across cohorts were diarrhea (G3 21%) and fatigue (G3 5%). No G4 AEs.
ctDNA HER2mut was detected in 72% (23/32) baseline (BL) samples tested. In pts with paired samples, HER2mut VAF decreased at C1D15/C2D1 from BL in 75% (15/20) and rose in 89% (16/18) at PD. Acquired HER2mut, including the T798I gatekeeper mutation, were detected in 2 pts at PD. Mutations in TP53 (53%), PIK3CA (43%), and CDH1 (35%) were common, but none significantly associated with PFS in all or ER+ pts.
Conclusions: NER, or N+F, is active for HER2mut MBC with good tolerability. Adding trastuzumab at PD induced further response, supporting dual HER2 blockade for HER2mut MBC.

Abstract
Abstract
Background: CDK 4/6 inhibitors in patients (pts) with HR+/HER2- ABC has led to significant improvements in clinical outcomes, however our understanding of the impact of these treatments on CV health is unknown. Gains in overall survival should not be offset by increased CV morbidity and mortality; a particular concern given the shared risk factors for both breast cancer and CV disease. Objective: The aim of this study was to describe patient characteristics, treatment patterns and cardiovascular risk factors and disease in pts with ABC treated with endocrine therapy (ET) or ET + CDK 4/6 inhibitor. Methods: We retrospectively studied pts with HR+/HER2- ABC who were receiving first line endocrine therapy. Post-menopausal (PM) women, pre-menopausal women on ovarian suppression (OS), and men were included. Two cohorts were included: Group A - treated with ET alone (2012-2014; prior to US approval of CDK 4/6 inhibitors) and Group B - treated with ET+ CDK 4/6 inhibitor (2015-2017). The following data was extracted from Duke University Health System’s electronic medical record (EPIC) and entered into a REDCap database: demographics, baseline cardiovascular risk factors, and co-morbidities. Pt characteristics are summarized using medians and interquartile ranges for continuous variables and categorical descriptions are summarized using frequencies and percentages. Results: In total 103 patients were included with 57 in Group A (ET alone) and 46 in Group B (ET + CDK 4/6 inhibitor). Median age was 62.0 and 63.5 years in Group A and B, respectively. Fifty-three (93%) of pts in Group A were PM women compared to 37 (80%) PM women and 1 (3%) male in Group B. The groups seemed to be similar in terms of race (white 70% vs 72%), baseline body mass index (28.2 vs 27.6), baseline systolic blood pressure (132.0 vs 135.5) and diastolic blood pressure (79.0 vs 77.5). Similarly, the groups seemed to be similar in baseline hypertension (68% vs 62%); diabetes (23% vs 24%); Hemoglobin A1c (7.2% vs 6.4%) or family history of CV disease (56% vs 55%), Group A versus Group B, respectively. There were slightly more current/past smokers in Group B than Group A (48% vs 35%) and more pts in Group A with a history of hyperlipidemia relative to Group B (52% vs 31%). Conclusions: In this retrospective descriptive cohort study there seemed to be no differences in demographics or baseline CV risk factors between the ET and ET + CDK 4/6 inhibitor cohorts with the exception of more baseline hyperlipidemia in the ET cohort. This might suggest that baseline CV risk factors did not dissuade practioners from prescribing ET + CDK 4/6 inhibitor therapy. We plan to expand our cohort to collect information on type and duration of ET and CDK 4/6 inhibitors, reason for treatment discontinuation, and CV events (eg heart failure, arrhythmias, stroke, myocardial infarction), to better understand the impact that cardiovascular risk factors have on outcomes in breast cancer patients taking ET+ CDk 4/6 inhibitor.

Abstract
Breast cancer is a disease of aging, and the incidence of breast cancer is projected to increase dramatically as the global population ages. The majority of breast cancers that occur in older adults are hormone-receptor positive, human epidermal growth factor receptor-2 (HER2)-negative phenotypes, with favorable tumor biology; yet, because of underrepresentation in clinical trials, less evidence is available to guide the complex care for this population. Providing care for older patients with metastatic breast cancer, with coexisting medical conditions, increased risk of treatment toxicity, and frailty, remains a clinical challenge in oncology. In this review, we provide an overview of the current evidence from clinical trials and subanalyses of older adults with hormone receptor-positive, HER2-negative metastatic breast cancer, highlighting data on the safety and efficacy of oral therapies, including endocrine therapy alone or in combination with cyclin-dependent kinase (CDK) 4/6 inhibitors, phosphatidylinositol 3-kinase (PI3K) inhibitors, and mammalian target of rapamycin (mTOR) inhibitors. In addition, we note the significant underrepresentation of older and frail adults in these studies. Current and future directions in research for this special population, in order to address significant knowledge gaps, include the need to improve long-term adherence to hormonal and targeted therapy, prospective clinical trials that capture clinical and biological aging endpoints, and the need for a multidisciplinary approach with integration of geriatric and oncology principles.

Abstract
PURPOSE Breast cancer patients with overall poor health are at a greater risk of both complications during treatment and mortality from competing causes. We sought to determine the association of pre-existing comorbidities on treatment-related complications and overall survival. METHODS We identified women ages 40-90 years old from our institutional registry with stage I-II invasive breast cancer from 2005 to 2014. Recursive partitioning was used to stratify women based on pre-existing comorbidities as low, moderate, or high risk of treatment-associated complications. Cox proportional hazards model was constructed to estimate the association of risk with overall survival. RESULTS 2077 women were studied. Mean age was 60 (IQR 51-68). Over half (54%) had ≥ 1 comorbid condition, and 29% experienced at least one adverse medical event within 1 year of diagnosis. Risk categories included low (no comorbidities or hypertension), moderate (combinations of comorbidities excluding congestive heart failure), and high (congestive heart failure in isolation or in combination with other conditions). High-risk women had a lower 10-year OS compared to moderate- or low-risk women (89% vs 90% vs 96%, log-rank p < 0.001). After adjustment, being at moderate (HR 2.20, 95% CI 1.30-3.72, p = 0.003) or high risk (HR 5.07, 95% CI 1.66-15.52, p = 0.004) of adverse sequelae was associated with reduced OS compared to those at low risk of these adverse medical events. CONCLUSIONS Following breast cancer diagnosis, overall poor health was associated with a greater risk of mortality and complications within the first year of treatment, which was driven by a pre-existing diagnosis of congestive heart failure.

Abstract
Breast cancer survivors with type 2 diabetes are at high risk for cancer recurrence, serious health complications, more severe symptoms, psychological distress, and premature death relative to breast cancer survivors without diabetes. Maintaining glycemic control is critical for decreasing symptoms and preventing serious health problems. Many breast cancer survivors with type 2 diabetes have difficulty maintaining diabetes self-management behaviors and achieving glycemic control. Both cancer and diabetes-related symptoms (e.g., physical symptoms and psychological distress) are often barriers to engaging in diabetes self-management strategies. This study evaluates a novel diabetes coping skills training (DCST) intervention for improving breast cancer survivors' abilities to manage symptoms and adhere to recommended diabetes self-management behaviors. The telephone-based DCST protocol integrates three key theory-based strategies: coping skills training for managing symptoms, adherence skills training, and healthy lifestyle skills training. A randomized clinical trial will test the DCST intervention plus diabetes education by comparing it to diabetes education alone. Symptoms, distress, diabetes self-management behaviors, and self-efficacy will be assessed at baseline and 3, 6, and 12 months. Glycosylated hemoglobin (HbA1c) will be assessed at baseline, 6, and 12 months. This study addresses a critical gap in the care of breast cancer survivors by evaluating a novel behavioral intervention to improve the management of symptoms, adherence, and glycemic control in breast cancer survivors with type 2 diabetes. Special considerations for this medically underserved population are also provided. The findings of this study could lead to significant improvements in clinical care and beneficial outcomes for breast cancer survivors.

Abstract
Abstract
Background: Meta-analyses have demonstrated that young women ≤40 (YW) derive the most benefit from chemotherapy (EBCTCG, Lancet. 1998). Oncotype DX was designed to determine the benefit of chemotherapy in women with ER+/HER2-, node-negative (LN-) breast cancer based on recurrence score (RS). TAILORx reported clinically meaningful benefits in freedom-from-distant recurrence in women <50 with the addition of chemotherapy to endocrine therapy when RS was 16-25. Recent TAILORx analyses suggest that women <40 with an intermediate (int) RS do not derive chemotherapy benefit, though YW comprised <4% of the trial population [1]. Defining the optimal adjuvant treatment strategy for this population of YW remains a clinical challenge. We sought to determine national patterns of RS utilization in association with receipt of chemotherapy and to characterize the association of RS with tumor characteristics and demographics among YW with early stage ER+, LN- breast cancer.
Methods: Using the National Cancer Data Base (NCDB), we identified individuals age <75, diagnosed 2010-2015 with stage I-II, ER+/HER2-, LN- breast cancer with known RS. Cohorts were defined as low (0-10), int (11-25), and high (>25) RS. Age categories were classified as ≤40, 41-50, and >50. Chi-square tests or Fisher’s exact tests were used to compare categorical variables. Logistic regression was used to estimate the association of RS score and age group with adjuvant chemotherapy use, after adjustment for known covariates. Kaplan-Meier curves were used to visualize unadjusted overall survival (OS), and Cox proportional hazards models were used to estimate adjusted OS.
Results: 120,051 women were identified, of whom 4,781 were ≤40 years, 24,846 were 41-50, and 90,424 were >50. By age group, 20% of YW had a high RS compared to 12% of women age 41-50 and 15% of women >50 (p<0.001). Among YW, black women were more likely than white women to have a high RS; 29% vs. 19% (p<0.001). RS was strongly associated with receipt of chemotherapy in YW (86% of high RS vs. 33% of int RS vs. 7% of low RS, p<0.001). Chemotherapy was omitted in 55% of YW with RS 16-25. YW in multivariate analysis with a low or int RS were more likely than women 41-50 or >50 to receive chemotherapy (p<0.001). Receipt of chemotherapy for YW with an int RS was associated with younger chronologic age (p<0.001), ductal histology (p=0.02), high grade (p<0.001), and higher pathologic T-stage (p<0.001). Among YW, the unadjusted 5-year OS (95% CI) was as follows: low RS= 100% (0.99-1), int RS= 100% (1-1), high RS= 93% (0.90-0.96). Chemotherapy did not influence 5 year OS in YW with an int RS. In univariate analysis, a high RS was associated with a worse 5-year OS in YW (log-rank p<0.001). After adjustment for race and chemotherapy receipt, high vs. low RS was associated with an increased risk of death (HR=5.86, 95% CI 1.19-28.82, p=0.03) in YW.
Conclusions: High RS is more common in YW (≤40) than those age 41-50 or >50, and is associated with worse OS. YW with an int or low RS are more likely to receive chemotherapy despite unclear benefit. Chemotherapy was omitted in over half of YW with RS of 16-25, highlighting the uncertainty in clinical practice which will remain until further studies inform optimal systemic treatment specific to YW.

Abstract
Abstract
Background: Side effects of and adherence to aromatase inhibitors in women with ductal carcinoma in situ are not well described. Methods: Postmenopausal women in a prospective phase II study of neoadjuvant letrozole for estrogen receptor positive DCIS completed questionnaires on side effects [Menopause Specific Quality of Life Questionnaire (MENQOL), Brief Pain Inventory-short form (BPI-SF), Arthritis Impact Measurement Scales (AIMS2)], well-being (FACT-G), and adherence [Medication-Taking questionnaire] at baseline, 1, 3 and 6 months (mo), and study completion. We used descriptive statistics and paired t-tests to compare 1, 3 and 6 mo results to baseline. Hierarchical linear mixed modeling, controlling for baseline symptom or well-being level, was used to examine effect of symptoms and well-being on intentional and nonintentional nonadherence, based on the Medication-Taking Questionnaire. Results: Included were 84 women, mean age 63 (39-83) years. In univariate analyses, compared to baseline, menopausal symptoms increased [physical (p=0.001 at 3, p<0.001 at 6 mo); vasomotor (p<0.001 at 1, 3, 6 mo), psychosocial (p=0.006 at 6 mo) and sexual (p=0.01 at 6 mo)]. Joint pain and stiffness increased [BPI-SF pain subscale (p=0.048 at 3, p=0.01 at 6 mo); AIMS2 joint pain subscale (p=0.03 at 1, p<0.001 at 3 and 6 mo); AIMS2 stiffness subscale (p=0.004 at 3, p=0.01 at 6 mo)]. Intentional and nonintentional adherence did not significantly change over time (p>0.05). Lower emotional (p=0.049) and functional (p=0.002) well-being by FACT-G and higher joint pain (p=0.03) by AIMS2 were associated with higher nonintentional nonadherence; higher physical side effects of menopause (p=0.001) by MENQOL were associated with lower intentional nonadherence. Conclusions: Among women taking letrozole for DCIS, menopausal symptoms and joint pain/stiffness increased over time with most differences noted at 3 and 6 mo. Lower well-being and higher symptom levels were associated with higher nonintentional nonadherence.

Abstract
OBJECTIVE Advanced breast cancer patients around the world experience high symptom burden (ie, distress, pain, and fatigue) and are in need of psychosocial interventions that target symptom management. This study examined the feasibility, acceptability, and engagement of a psychosocial intervention that uses cognitive-behavioral strategies along with mindfulness and values-based activity to enhance patients' ability to manage symptoms of advanced disease in a cross-cultural setting (United States and Singapore). Pre-treatment to post-treatment outcomes for distress, pain, and fatigue were compared between intervention recipients and waitlisted controls. METHODS A pilot randomized controlled trial included women with advanced breast cancer (N = 85) that were recruited in the United States and Singapore. Participants either received the four session intervention or be put on waitlist. Descriptive statistics and effect size of symptom change were calculated. RESULTS The psychosocial intervention was found to be feasible as indicated through successful trial accrual, low study attrition (15% ), and high intervention adherence (77% completed all sessions). Acceptability (ie, program satisfaction and cultural sensitivity) and engagement to the study intervention (ie, practice of skills taught) were also high. Anxiety, depression, and fatigue scores remained stable or improved among intervention participants while the same symptoms worsened in the control group. In general, effect sizes are larger in the US sample compared with the Singapore sample. CONCLUSIONS The cognitive-behavioral, mindfulness, and values-based intervention is feasible, acceptable, and engaging for advanced breast cancer patients in a cross-cultural setting and has potential for efficacy. Further larger-scaled study of intervention efficacy is warranted.

Abstract
Background To explain the association between adjuvant radiation therapy after breast conserving surgery (BCS RT) and overall survival (OS) by quantifying bias due to confounding in a sample of elderly breast cancer beneficiaries in a multi-state region of Appalachia. Methods We used Medicare claims linked registry data for fee-for-service beneficiaries with AJCC stage I-III, treated with BCS, and diagnosed from 2006 to 2008 in Appalachian counties of Kentucky, Ohio, North Carolina, and Pennsylvania. Confounders of BCS RT included age, rurality, regional SES, access to radiation facilities, marital status, Charlson comorbidity, Medicaid dual status, institutionalization, tumor characteristics, and surgical facility characteristics. Adjusted percent change in expected survival by BCS RT was examined using Accelerated Failure Time (AFT) models. Confounding bias was assessed by comparing effects between adjusted and partially adjusted associations using a fully specified structural model. Results The final sample had 2675 beneficiaries with mean age of 75, with 81% 5-year survival from diagnosis. Unadjusted percentage increase in expected survival was 2.75 times greater in the RT group vs. non-RT group, with 5-year survival of 85% vs 60%; fully adjusted percentage increase was 1.70 times greater, with 5-year rates of 83% vs 71%. Quantification of incremental confounding showed age accounted for 71% of the effect reduction, followed by tumor features (12%), comorbidity (10%), dual status(10%), and institutionalization (8%). Adjusting for age and tumor features only resulted in only 4% bias from fully adjusted percent change (70% change vs 66%). Conclusion Quantification of confounding aids in determining covariates to adjust for and in interpreting raw associations. Substantial confounding was present (60% of total association), with age accounting for the largest share (71%); adjusting for age plus tumor features corrected for most of the confounding (4% bias). The direct effect of BCS RT on OS accounted for 40% of the total association.

Abstract
Members of the Translational Breast Cancer Research Consortium conducted an expert-driven literature review to identify a list of domains and to evaluate potential measures of these domains for inclusion in a list of preferred measures. Measures were included if they were easily available, free of charge, and had acceptable psychometrics based on published peer-reviewed analyses. A total of 22 domains and 52 measures were identified during the selection process. Taken together, these measures form a reliable and validated list of measurement tools that are easily available and used in multiple cancer trials to assess patient-reported outcomes in relevant patients.

Abstract
Background: BRCA mutated (BRCA+) breast cancers are expected to have increased activation of Homologous Recombination Deficiency (HRD) and altered DNA damage repair pathways when compared to BRCA wildtype (BRCA-). To better understand differences in these populations, biological patterns and immune responses to BRCA+ breast cancers were evaluated. The primary aim of our study was to use novel gene expression tools to assess early stage breast cancers with and without germline BRCA mutations, and within distinct BRCA+ subgroups.
Methods: We identified 124 early stage untreated breast cancers with and without BRCA mutations (n = 62 and 62, respectively). Our BRCA- group was matched by hormone receptor (HR) status, age, and stage to the BRCA+ group. The NanoString Breast Cancer 360 panel was applied to RNA isolated from 80 breast tumors (BRCA+ = 39; BRCA- = 41). The BRCA+ group had a BRCA1+ subgroup (n=17) and a BRCA2+ subgroup (n=22).
Results: There was a significant increase in two BC360 signatures in both the BRCA1+ and BRCA2+ tumors compared with the BRCA- population: Prosigna™Risk of Recurrence (ROR) score [BRCA1+: HR: 1.142 (95% CI 1.019, 1.279), p=0.02; BRCA2+: HR: 1.321 (95% CI 1.190, 1.466), p<0.001] and HRD [BRCA1+: HR: 3.576 (95% CI 2.174, 5.880), p=0.02; BRCA2+: HR: 1.801 (95% CI 1.142, 2.840), p<0.001]. BRCA1+ tumors had lower expression of ESR1 [p=0.03], PGR [p=0.02], ER signaling [p<0.001], and differentiation [p=0.005]; while BRCA2+ tumors had lower expression of stroma markers [p=0.02] and inflammatory chemokines [p=0.001]. The two BRCA+ subgroups had distinct molecular subtype correlation trends that were highly significant. BRCA1+ tumors were positively associated with a basal subtype [p<0.001], whereas this association was not significant for BRCA2+ tumors. BRCA2+ tumors were associated with an increase in luminal B subtype [p=0.05]. All BRCA+ tumors had a decrease in luminal A subtype correlation [BRCA1+: p<0.001; BRCA2+: p=0.002]. In addition to the BC360 signatures, a differential analysis of all genes in the BC360 panel revealed more single gene differences in BRCA2+ than BRCA1+ tumors when compared to BRCA- tumors.
Conclusions: In early stage BRCA+ breast cancer, tumors have higher ROR and increased HRD signature scores compared to BRCA- tumors. Furthermore, BRCA1+ and BRCA2+ tumors have both signature and single gene expression differences when compared to BRCA- tumors, indicating distinct subgroup-related biology. The greater correlation of BRCA1+ tumors with basal-like biology and BRCA2+ tumors with aggressive hormonal biology confirms these trends. Distinctions in hormone receptor signaling, DNA-damage pathways, and microenvironment/inflammatory features between BRCA1 and BRCA2 associated cancers suggest a need for different prevention and therapeutic strategies for each of these breast cancer subtypes. The unique biological patterns identified here should be further evaluated as predictive or prognostic tools that could be translated into clinical care for early stage BRCA+ patients.

Abstract
Adjuvant endocrine therapy (AET) is used to prevent recurrence and reduce mortality for women with hormone receptor positive breast cancer. Poor adherence to AET is a significant problem and contributes to increased medical costs and mortality. A variety of problematic symptoms associated with AET are related to non-adherence and early discontinuation of treatment. The goal of this study is to test a novel, telephone-based coping skills training that teaches patients adherence skills and techniques for coping with problematic symptoms (CST-AET). Adherence to AET will be assessed in real-time for 18 months using wireless smart pill bottles. Symptom interference (i.e., pain, vasomotor symptoms, sleep problems, vaginal dryness) and cost-effectiveness of the intervention protocol will be examined as secondary outcomes. Participants (N = 400) will be recruited from a tertiary care medical center or community clinics in medically underserved or rural areas. Participants will be randomized to receive CST-AET or a general health education intervention (comparison condition). CST-AET includes ten nurse-delivered calls delivered over 6 months. CST-AET provides systematic training in coping skills for managing symptoms that interfere with adherence. Interactive voice messaging provides reinforcement for skills use and adherence that is tailored based on real-time adherence data from the wireless smart pill bottles. Given the high rates of non-adherence and recent recommendations that women remain on AET for 10 years, we describe a timely trial. If effective, the CST-AET protocol may not only reduce the burden of AET use but also lead to cost-effective changes in clinical care and improve breast cancer outcomes.

Abstract
PURPOSE A few previous studies report a direct relationship between older age and chemotherapy-induced neuropathy. This study further evaluated this adverse event's age-based risk. METHODS CALGB 40101 investigated adjuvant paclitaxel (80 mg/m2 once per week or 175 mg/m2 every 2 weeks) in patients with breast cancer and served as a platform for the current study that investigated age-based differences in neuropathy. Grade 2 or worse neuropathy, as per Common Terminology Criteria for Adverse Events version 4, was the primary endpoint; patients were assessed at baseline, every 6 months for 2 years, and then annually for 15 years. RESULTS Among these 1,881 patients, 230 were 65 years of age or older, 556 were 55-64 years, and 1,095 were younger than 55; 1,226 neuropathy events (commonly grade 1 or 2) were reported in 65% of the cohort. The number of grade 2 or worse events was 63 (27%), 155 (28%), and 266 (24%) within respective age groups (p = .14). In univariate analysis, only motor neuropathy had a higher age-based incidence: 19 (8%), 43 (8%), and 60 (5%), respectively (p = .04); in multivariate analyses, this association was no longer statistically significant. Other endpoints, such as time to onset of neuropathy (time from trial enrollment to neuropathy development) and time to improvement (time from maximal grade sensory neuropathy to a one-category improvement), showed no statistically significant age-based differences. In contrast, obesity was associated with neuropathy, and every 2-week paclitaxel was associated with trends toward neuropathy. CONCLUSION Although paclitaxel-induced neuropathy is common, older age is not an independent risk factor. Clinical trial identification number. NCT00041119 (CALGB 40101). IMPLICATIONS FOR PRACTICE Age alone is not an independent risk factor for paclitaxel-induced neuropathy.

Abstract
OBJECTIVES To analyze self-reported changes in physical function in older women with breast cancer receiving adjuvant chemotherapy. DESIGN Secondary analysis of the Cancer and Leukemia Group B (CALGB) 49907 prospective randomized clinical trial. SETTING CALGB institutions in the United States. PARTICIPANTS Women aged 65 and older with Stage I to III breast cancer enrolled in CALGB 49907 who had physical function data from before and after receipt of adjuvant chemotherapy (N=256; mean age 71.5, range 65-85). MEASUREMENTS Participants were administered the physical function subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire before chemotherapy, at the end of chemotherapy, and 12 months after chemotherapy initiation. Functional decline was defined as a more than 10-point decrease from baseline at each time point. Resilience was defined as return to within 10 points of baseline. Multivariable regression was used to examine pretreatment characteristics associated with physical function changes. RESULTS Of 42% of participants who had physical function decline from before to the end of chemotherapy, 47% recovered by 12 months (were resilient). Almost one-third experienced functional decline from before chemotherapy to 12 months later. Pretreatment fatigue was a risk factor for functional decline from before to the end of chemotherapy (P=.02). Risk factors for functional decline at 12 months included pretreatment dyspnea (P=.007) and being unmarried (P=.01). CONCLUSION Functional decline was common in older women receiving adjuvant chemotherapy for breast cancer in a clinical trial. Although half recovered their physical function, one-third had a clinically meaningful decline at 12 months. Strategies are needed to prevent functional decline in older adults receiving chemotherapy. J Am Geriatr Soc 67:920-927, 2019.

A randomized phase II trial of MOVING ON: An intervention to increase exercise outcome expectations among breast cancer survivors. Psychooncology 2018; 27:2450-2457. [PMID: 30071146 DOI: 10.1002/pon.4849] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Revised: 07/19/2018] [Accepted: 07/20/2018] [Indexed: 11/11/2022]
Abstract
OBJECTIVE The objective of the study is to test theoretical intervention fidelity and feasibility of MOVING ON, a self-directed, home-based, randomized controlled trial to increase exercise outcome expectations (OEs) (what one expects to obtain or avoid as a result of a behavior or lack thereof), among breast cancer survivors. METHOD Stage Ia to IIb survivors (n = 60) were given the MOVING ON intervention or control booklet. Data were collected through online surveys and an accelerometer at baseline, 4, 8, and 12 weeks postintervention. Fidelity was measured by questions assessing participant perceptions of MOVING ON (score ≥2) and direction of intervention effects. Feasibility was measured by recruitment rate (target of 60 participants in 6 months), retention (total attrition <17%), and acquisition of accelerometer data (% ≥subjective exercise data obtained). Analyses consisted of descriptive statistics, mixed models, and content analysis. RESULTS Fidelity met a priori criteria (mean = 3.31, SD = 0.87). Outcome expectations increased 0.01 points, and weekly steps increased by 970 every 4 weeks in the intervention arm compared to the control arm. All effect sizes were small, ranging from 0.01 to 0.09. Target enrollment, achieved in 17 weeks, met a priori feasibility criteria. Retention (66%) and accelerometer data acquisition (60%) (compared to 73% of subjective exercise data) did not. CONCLUSION MOVING ON influenced OEs as intended and was well received by participants. A fully powered study, of this low-cost, easy-to-implement intervention, is warranted. Intervention and measurement strategies used in MOVING ON can be incorporated in any study targeting OEs as a mediator of exercise or collecting exercise data with an accelerometer.
