BACKGROUND: The conventional radiotherapy (CRT) in postmastectomy breast cancer is 1.8-2.0 Gy daily for 25 fractions, while hypofractionated radiotherapy (HFRT) delivered dose in fewer fractions with larger radiation intensity. The present study compares the efficacy of HFRT and CRT. MATERIAL AND METHOD: From 2004 to 2006, 215 patients were retrospectively reviewed. Sixty seven patients received CRT and 148 patients received HFRT (2.65 Gy in 16-18 fractions). Five-year locoregional control (LRC), disease free survival (DFS), overall survival (OS) and toxicities were analyzed. RESULTS: Median follow-up was 39 months. Five-year LRC was 86.6% in CRT and 85.8% in HFRT (p = 0.852). Five-year DFS was 62.7% and 69.6% (p = 0.136) in CRTand HFRT respectively. Patients who received HFRT had significant increase in 5-year OS (62.7% and 73.0% (p = 0.048). No difference of toxicities including changes in chest wall appearance, skin fibrosis, brachial plexopathy, arm edema, pulmonary fibrosis, rib fractures and cardiovascular events was found between two groups. CONCLUSION: HFRT is as effective as CRT in postmastectomy breast cancer.
