    Abstract

    Purpose To report the first comprehensive investigation of patient-reported cosmesis and breast-related quality of life (QOL) outcomes comparing patients randomized to risk-adapted single-dose intraoperative radiation therapy (TARGIT-IORT) versus external beam radiation therapy (EBRT) on the TARGIT-A trial. Methods and Materials Longitudinal cosmesis and QOL data were collected from a subset of TARGIT-A participants who received TARGIT-IORT as a separate procedure (postpathology). Patients completed a cosmetic assessment before radiation therapy and annually thereafter for at least 5 years. Patients also completed the combined European Organization for Research and Treatment of Cancer (EORTC) core questionnaire and Breast-Specific Module in addition to the Body Image after Breast Cancer Questionnaire at baseline and annually thereafter. The combined EORTC questionnaires were also collected 3, 6, and 9 months after wide local excision. Results An Excellent–Good cosmetic result was scored more often than a Fair–Poor result for both treatment groups across all time points. The TARGIT-IORT patients reported better breast-related QOL than EBRT patients. Statistically and clinically significant differences were seen at month 6 and year 1, with EBRT patients having moderately worse breast symptoms (a statistically significant difference of more than 10 in a 100-point scale) than TARGIT-IORT patients at these time points. Conclusion Patients treated with TARGIT-IORT on the TARGIT-A trial have similar self-reported cosmetic outcome but better breast-related QOL outcomes than patients treated with EBRT. This important evidence can facilitate the treatment decision-making process for patients who have early breast cancer suitable for breast-conserving surgery and inform their clinicians. © 2016 The Authors
