从1985年1月～1990年1月，我们对76例乳癌术后患者进行了放疗。Ⅱ期54例、Ⅲ期18例、Ⅳ期4例。放疗采用60钴γ线或6mv一x线、10～12mev电子线。照射胸壁、内乳、锁骨上、腋下等区域。放疗剂量45～50Gy／4．5～5周，5年生存率Ⅱ期80．6％（25／31）、Ⅲ期33．3％（3／9）、Ⅳ期25％（1／4）。我们认为放疗对Ⅱ期以上的患者可降低复发率、提高生存率
From January 1985 to January 1990, we performed radiotherapy on 76 patients with postoperative breast cancer. There were 54 patients in stage II, 18 in stage III, and 4 in stage IV. Radiotherapy uses 60-cobalt gamma rays or 6mV-x-rays and 10-12 meV electron rays. Irradiation of the chest wall, internal milk, supraclavicular, infraorbital and other areas. Radiotherapy dose 45 to 50 Gy/4.5 to 5 weeks, 5-year survival rate of 80.6% (25/31) in Phase II, 33.3% (3/9) in Phase III, and 25% in Phase IV (1/4) . We believe that radiotherapy can reduce the recurrence rate and improve survival rate in patients with stage II or above
