1目的　探讨乳癌保留乳房手术的可行性。 2方法　将 90例 , 期乳癌病人随机分为两组 ,保留乳房手术组 42例 ,采用乳腺区段切除加腋窝淋巴结清扫术 ;改良根治术组 48例 ,采用乳腺全切加腋窝淋巴结清扫术。术后两组均行放疗、化疗和内分泌治疗 ,比较两组治疗效果及并发症发生情况。 3结果　乳癌保留乳房手术组3年生存率为 95 .2 % ,5年生存率为 91.7% ,发生并发症 4例 ;改良根治术组 3年生存率为 95 .8% ,5年生存率为92 .1% ,发生并发症 7例 ,两组 3年及 5年生存率比较 ,差异无显著性 (χ2 =0 .14,0 .2 5 ,P>0 .0 5 )。 4结论　乳癌保留乳房手术效果完全能和改良根治术相媲美 1 Objective To explore the feasibility of breast cancer preservation breast surgery. 2 Methods 90 cases of breast cancer patients were randomly divided into two groups, retained 42 cases of breast surgery group, the use of breast segment resection plus axillary lymph node dissection; modified radical surgery group of 48 cases, using breast full cut plus axillary lymph node dissection. Radiotherapy, chemotherapy, and endocrine therapy were performed in both groups after surgery. The treatment effects and complications of the two groups were compared. 3 Results The 3-year survival rate of breast cancer-preserving breast surgery group was 95.2%, the 5-year survival rate was 91.7%, and 4 complications occurred; the 3-year survival rate of the modified radical mastectomy group was 95.8%. The 5-year survival rate was 92.1% of the patients had complications in 7 cases. There was no significant difference between the two groups in the 3-year and 5-year survival rates (χ2 = 0.14, 0.25, P> 0.05). 4 Conclusion Breast cancer retains breast surgery completely comparable to modified radical mastectomy
