【摘要】 目的　探讨乳腺癌根治术后胸壁和 /或区域淋巴结复发放射治疗的预后因素。方法　 1992年 3月至 1995年 5月共收治 93例患者 ,均为女性 ,复发时间在术后 1月至 19年不等。复发部位照射剂量 5 0～ 70GY/ 5～ 7w ,部份病例照射了淋巴引流区。结果　本组病例的 3年、5年生存率分别是 5 1.6 %和 39.3%。术后 5年内和 5年以上复发病例的 5年生存率分别是 38.0 %和 6 9.2 % (P <0 .0 5 )。结论　放射治疗对乳腺癌术后复发有挽救作用 ,手术与复发的间隔时间超过5年 ,预后好。更多还原

【Abstract】 Objective To investigate the factors affecting the prognosis of radiotherapy in local/regional nodal failure after radical mastectomy for breast cancer.Methods From March,1992 to May,1995,93 patients of breast cancer after radical mastectomy were treated.All were female.The duration of relapse time was from 1 month to 19 years after operation.The irradiation methods included local irradiation and regional irradiation.The total dose was 50～70GY/5～7 weeks.Results The 3-year and 5-year survival rates were 51.6%,39.3% respectively.The 5-year survival rate of patients whose lesions recurred within five years after operation was 38.0%,which was lower than that of those whose lesions recurred beyond five years of operation,69.2%(P<0.05).Conclusion Radiotherapy is one of salvaging means for the patients with local/regional nodal failure after radical mastectomy for breast cancer.The interval between the operation and relapse is longer than 5 years.更多还原
