Abstract
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. Patient-reported measures were collected at baseline (pretreatment) and post-treatment using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) measure, which consists of 5 subscales. Changes in mean QOL scores in patients who received radiotherapy were compared to those who did not using a one-sided noninferiority method. Statistical significance was determined below 0.05 to meet noninferiority.
Results
In a sample of 175 patients, 131 were treated with radiation and 44 had no radiation. The sample consisted mostly of stage I-II breast cancer (78%) with hormone receptor positive (59%) disease, receiving either neoadjuvant (36%) or adjuvant chemotherapy (64%). Mean change in QOL for the group treated with radiation compared to no radiation was noninferior with respect to Physical Well-Being (P = .0027), Social/Family Well-Being (P = .0002), Emotional Well-Being (P = .0203), FACIT-Fatigue Subscale (P = .0072), and the Total FACIT-F score (P = .0005); however, mean change in QOL did not meet noninferiority for Functional Well-Being (P = .0594).
Conclusion
Patient-reported QOL from baseline to post-treatment, using the Total FACIT-F score, was noninferior in patients treated with versus without radiation therapy. This finding, in addition to individualized QOL subscales, provides important information in the informed decision-making process when discussing the effects of locoregional radiation on QOL in localized breast cancer patients treated with chemotherapy.
期刊介绍：
Clinical Breast Cancer is a peer-reviewed bimonthly journal that publishes original articles describing various aspects of clinical and translational research of breast cancer. Clinical Breast Cancer is devoted to articles on detection, diagnosis, prevention, and treatment of breast cancer. The main emphasis is on recent scientific developments in all areas related to breast cancer. Specific areas of interest include clinical research reports from various therapeutic modalities, cancer genetics, drug sensitivity and resistance, novel imaging, tumor genomics, biomarkers, and chemoprevention strategies.
