PROMs following breast-conserving therapy for breast cancer: results from a prospective longitudinal monocentric study

Background Treatment of breast cancer includes many options and shared decision making is becoming standard practice. Within the context of treatment individualization, the omission of radiotherapy (RT) can be considered. It is thereby of great importance to correctly foresee the side effects attributed to RT. Data from longitudinal studies with contemporary techniques however are sparse. The purpose of the present study was to evaluate patient-reported outcome measures (PROMs) and long-term aesthetic outcome (AO) related to RT in the breast-conserving therapy (BCT) setting for breast cancer over time.
