    Breast Cancer Patients’ Insurance Status and Residence Zip Code Correlates with Early Discontinuation of Endocrine Therapy: Analysis of ECOG-ACRIN TAILORx Trial
    (Wiley, 2021) Sadigh, Gelareh; Gray, Robert J.; Sparano, Joseph A.; Yanez, Betina; Garcia, Sofia F.; Timsina, Lava R.; Sledge, George W.; Cella, David; Wagner, Lynne I.; Carlos, Ruth C.; Surgery, School of Medicine
    Background: Early discontinuation is a substantial barrier to the delivery of endocrine therapies (ETs) and may influence recurrence and survival. The authors investigated the association between early discontinuation of ET and social determinants of health, including insurance coverage and the neighborhood deprivation index (NDI), which was measured on the basis of patients' zip codes, in breast cancer. Methods: In this retrospective analysis of a prospective randomized clinical trial (Trial Assigning Individualized Options for Treatment), women with hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer who started ET within a year of study entry were included. Early discontinuation was calculated as stopping ET within 4 years of its start for reasons other than distant recurrence or death via Kaplan-Meier estimates. A Cox proportional hazards joint model was used to analyze the association between early discontinuation of ET and factors such as the study-entry insurance and NDI, with adjustments made for other variables. Results: Of the included 9475 women (mean age, 55.6 years; White race, 84%), 58.0% had private insurance, whereas 11.7% had Medicare, 5.8% had Medicaid, 3.8% were self-pay, and 19.1% were treated at international sites. The early discontinuation rate was 12.3%. Compared with those with private insurance, patients with Medicaid (hazard ratio [HR], 1.53; 95% confidence interval [CI], 1.23-1.92) and self-pay patients (HR, 1.65; 95% CI, 1.25-2.17) had higher early discontinuation. Participants with a first-quartile NDI (highest deprivation) had a higher probability of discontinuation than those with a fourth-quartile NDI (lowest deprivation; HR, 1.34; 95% CI, 1.11-1.62). Conclusions: Patients' insurance and zip code at study entry play roles in adherence to ET, with uninsured and underinsured patients having a high rate of treatment nonadherence. Early identification of patients at risk may improve adherence to therapy. Lay summary: In this retrospective analysis of 9475 women with breast cancer participating in a clinical trial (Trial Assigning Individualized Options for Treatment), Medicaid and self-pay patients (compared with those with private insurance) and those in the highest quartile of neighborhood deprivation scores (compared with those in the lowest quartile) had a higher probability of early discontinuation of endocrine therapy. These social determinants of health assume larger importance with the expected increase in unemployment rates and loss of insurance coverage in the aftermath of the coronavirus disease 2019 pandemic. Early identification of patients at risk and enrollment in insurance optimization programs may improve the persistence of therapy.

    Randomized Phase III Postoperative Trial of Platinum-Based Chemotherapy Versus Capecitabine in Patients With Residual Triple-Negative Breast Cancer Following Neoadjuvant Chemotherapy: ECOG-ACRIN EA1131
    (American Society of Clinical Oncology, 2021) Mayer, Ingrid A.; Zhao, Fengmin; Arteaga, Carlos L.; Symmans, William F.; Park, Ben H.; Burnette, Brian L.; Tevaarwerk, Amye J.; Garcia, Sofia F.; Smith, Karen L.; Makower, Della F.; Block, Margaret; Morley, Kimberly A.; Jani, Chirag R.; Mescher, Craig; Dewani, Shabana J.; Tawfik, Bernard; Flaum, Lisa E.; Mayer, Erica L.; Sikov, William M.; Rodler, Eve T.; Wagner, Lynne I.; DeMichele, Angela M.; Sparano, Joseph A.; Wolff, Antonio C.; Miller, Kathy D.; Medicine, School of Medicine
    Purpose: Patients with triple-negative breast cancer (TNBC) and residual invasive disease (RD) after completion of neoadjuvant chemotherapy (NAC) have a high-risk for recurrence, which is reduced by adjuvant capecitabine. Preclinical models support the use of platinum agents in the TNBC basal subtype. The EA1131 trial hypothesized that invasive disease-free survival (iDFS) would not be inferior but improved in patients with basal subtype TNBC treated with adjuvant platinum compared with capecitabine. Patients and methods: Patients with clinical stage II or III TNBC with ≥ 1 cm RD in the breast post-NAC were randomly assigned to receive platinum (carboplatin or cisplatin) once every 3 weeks for four cycles or capecitabine 14 out of 21 days every 3 weeks for six cycles. TNBC subtype (basal v nonbasal) was determined by PAM50 in the residual disease. A noninferiority design with superiority alternative was chosen, assuming a 4-year iDFS of 67% with capecitabine. Results: Four hundred ten of planned 775 participants were randomly assigned to platinum or capecitabine between 2015 and 2021. After median follow-up of 20 months and 120 iDFS events (61% of full information) in the 308 (78%) patients with basal subtype TNBC, the 3-year iDFS for platinum was 42% (95% CI, 30 to 53) versus 49% (95% CI, 39 to 59) for capecitabine. Grade 3 and 4 toxicities were more common with platinum agents. The Data and Safety Monitoring Committee recommended stopping the trial as it was unlikely that further follow-up would show noninferiority or superiority of platinum. Conclusion: Platinum agents do not improve outcomes in patients with basal subtype TNBC RD post-NAC and are associated with more severe toxicity when compared with capecitabine. Participants had a lower than expected 3-year iDFS regardless of study treatment, highlighting the need for better therapies in this high-risk population.

    Symptom and needs assessment screening in oncology patients: Alternate outreach methods during COVID-19
    (Taylor & Francis, 2021) Davis, Kristina; Wilbur, Kayla; Metzger, Susan; Garcia, Sofia F.; Cahue, September; Webster, Kimberly; Lylerohr, Madison; Himelhoch, Heather L.; Bilimoria, Karl; Cella, David; Surgery, School of Medicine
    Patients with cancer are ideally screened for symptoms, including distress, using patient-reported outcome measures (PROMs). This initiative was developed to ensure patients without access to an electronic portal were screened for distress and related symptoms during the COVID-19 pandemic. Prior to the pandemic, these patients could complete screening in clinic. However, many visits transitioned to telehealth. We implemented a standardized telephone outreach process targeting patients without active electronic portal accounts to improve remote symptom monitoring. Outreach resulted in 172 completed screens, identifying 110 needs for 63 individuals. Twenty-eight patients completed patient portal enrollment. Outreach calls captured a higher percentage of Black patients (34%) and a higher percentage of 61-80 year olds (69%) compared to portal users. Telephone outreach during the pandemic captured data that otherwise would have been missed in elderly and minority patients without electronic patient portal access. Patient engagement is vital to the distress screening process.
