目的 :进一步证实放射治疗在早期乳腺癌保乳术中的重要性。方法 :1994年 12月～ 2 0 0 1年 12月本院共收治 2 3 7例早期乳腺癌。其中 83例做保乳手术。 154例做改良根治术。保乳术后全部患者接受放疗。放疗的范围根据肿块的大小、部位、腋淋巴结是否受累而定。胸壁切线剂量予 8MV X线 50 0 0cGy。肿瘤瘤床加电子线 150 0cGy。改良根治术后仅 3例作放疗。 结果 :保乳组和改良组局部复发各 1人。保乳组区域淋巴结复发 1例。改良组无区域淋巴结复发 ,有肝转移、肺转移各 1人。两组各死亡 1人。保乳组五年生存率 96.49% ,改良组98.61%。保乳组双侧乳房外形基本一致 ,柔软 ,有弹性。结论 :早期乳腺癌保乳术加放射治疗 ,效果与改良根治术相似 ,并伴良好美容效果
Objective: To further confirm the importance of radiotherapy in breast conserving surgery. Methods: December 1994 ~ December 2001 in our hospital were treated a total of 237 cases of early breast cancer. 83 cases of breast-conserving surgery. 154 cases of modified radical mastectomy. After breast-conserving surgery all patients receive radiotherapy. The scope of radiotherapy according to the size of the tumor, site, axillary lymph nodes are involved. Chest wall tangent dose to 8MV X line 50 0 0cGy. Tumor bed with electron beam 150 0cGy. Modified radical mastectomy only 3 cases for radiotherapy. Results: Breast-conserving group and improving group local recurrence one person each. One case of regional lymph node recurrence in breast - conserving group. There was no regional lymph node recurrence in the improved group, with one liver metastasis and one lung metastasis. 1 in each group died. The five-year survival rate of breast-conserving group was 96.49%, and the improvement group was 98.61%. Breast-conserving group bilateral breast shape is basically the same, soft, flexible. Conclusion: Early breast conserving surgery plus radiotherapy, the effect is similar to modified radical mastectomy, with good cosmetic results
