Abstract

Women treated with chest radiation for Hodgkin lymphoma (HL) have significantly higher risk of developing breast cancer, and little is known about how these patients tolerate chemotherapy for breast cancer. This small retrospective study identified 15 patients, noting that these patients tolerate proposed chemotherapy regimens for breast cancer in rates similar to those without prior HL and therapeutic radiation. Purpose: Women treated for Hodgkin lymphoma (HL) with chest radiation have significantly higher risk of developing breast cancer, and little is known about how these patients tolerate chemotherapy for breast cancer. Methods: Women with breast cancer diagnosed from 1986–2015 after radiation for HL were identified from hospitals and clinics in St. Paul and Minneapolis, Minnesota. Patient, tumor and treatment characteristics, and clinical outcomes were abstracted from medical records and summarized using descriptive statistics. Chemotherapy was defined as tolerated if all scheduled doses and cycles were completed without deviation from the initial plan, with lack of grade 3 or higher toxicity attributable to chemotherapy in categories including blood, cardiac, gastrointestinal, fatigue and pain. Results: Forty-two patients with breast cancer and prior radiation for HL were identified, 15 of which received chemotherapy for breast cancer. We noted 75% tolerability of taxane-based and 100% tolerability of anthracycline-based chemotherapy, suggesting that most patients with prior radiation for HL tolerate chemotherapy for breast cancer. A subset of patients (N = 7) in this study were also treated with chemotherapy for HL prior to breast cancer diagnosis, and 86% (6 of 7) also tolerated chemotherapy for breast cancer. Conclusions: Treatment of breast cancer is strongly influenced by prior treatment of HL. Although this study was small and did not meet statistical significance, the data suggest that these patients tolerate proposed chemotherapy regimens for breast cancer in rates similar to those without prior HL and therapeutic radiation. Larger studies comparing specific chemotherapy dosing schedules are needed to address this complicated population.
