Abstract: Objective To investigate the short?term complications and cosmetic outcomes of radiotherapy in breast conserving surgery for early?stage breast cancer. Methods A retrospective analysis was performed on clinical data from 30 patients with early?stage breast cancer from 2013 to 2015. All patients underwent breast conserving surgery combined with intraoperative low?energy X?ray radiotherapy. The prescribed dose was 20 Gy at the surface of the applicator. Local complications, radiation injury, and cosmetic outcomes were observed after surgery. Results No grade 3?4 adverse reactions were found in patients. In terms of short?term complications, four patients (13%) had seroma, two of whom needed suction treatment;three patients ( 10%) had grade 1?2 skin erythema. Half of the patients had excellent cosmetic outcomes. None of the patients had local recurrence or distant metastasis. Conclusions Intraoperative low?energy X?ray radiotherapy is safe and feasible in breast conserving surgery for breast cancer. It can be considered as an optional approach for tumor bed boost in some patients with early?stage low?risk breast cancer.
