目的 对87例乳癌根治术或改良根治术后局部放疗病人进行临床分析。方法 选择1991～1994年我院收治的乳癌术后放疗病人,照射部位为患侧锁骨上下区,内乳淋巴链区、腋窝区、胸壁,照射靶区剂量45至55GY,4～6周,并进行5年随访。结果 Ⅱ_b期5年生存率65.6％,Ⅲ期5年生存率48.9％,腋窝淋巴结转移数目1～3个5年生存率77.8％,4～9个5年生存率43.3％,大于或等于10个5年生存率27.3％。结论 ⅡⅢ期乳癌局部放疗确能降低区域复发率,改善生存质量。腋淋巴结转移数目与预后呈正相关。
Objective To perform clinical analysis of 87 cases of localized radiotherapy after radical mastectomy or modified radical mastectomy. METHODS: Patients with postoperative radiotherapy for breast cancer treated in our hospital from 1991 to 1994 were selected. The irradiation site was the upper and lower clavicle region of the affected side, the inner breast lymph node region, the axillary region, and the chest wall. The dose of the irradiation target ranged from 45 to 55 GY for 4 to 6 weeks. Five-year follow-up. Results The 5-year survival rate was 65.6% in stage IIb, and the 5-year survival rate was 48.9% in stage III. The number of axillary lymph node metastases was 1 to 3 and the 5-year survival rate was 77.8%. The 4 to 9 5-year survival rate was 43.3% and was greater than or equal to 10 The 5-year survival rate was 27.3%. Conclusion Part II stage III breast cancer local radiotherapy can really reduce the regional recurrence rate and improve the quality of life. Axillary lymph node metastasis was positively correlated with the prognosis.
