探讨根治术后放疗对Ⅱ期乳癌的远期疗效。方法：选Ⅱ期乳癌术后行放射治疗53例与术后未行放射治疗者93例进行对比分析。结果：术后放疗组的10年生存率66%(35/53)，单纯手术组68.8%(64/93)。但术后放疗组中区域淋巴结转移者81.1%(43/53)，而单纯手术组仅5.4%(5/93)。放疗组中DT<50Gy的10年生存率52%(13/25)，DT≥50Gy为78.6%(22/28)。结论：Ⅱ期乳癌根治术后常规作区域淋巴结放疗，且DT≥50Gy可以提高患者的生存率。
To investigate the long-term efficacy of radical radiotherapy for stage II breast cancer. Methods: A total of 53 cases of stage II breast cancer after radiotherapy and 93 cases without radiotherapy were compared and analyzed. RESULTS: The postoperative radiotherapy group had a 10-year survival rate of 66% (35/53) and a 68.8% (64/93) surgery alone group. However, 81.1% (43/53) of regional lymph node metastases were found in the postoperative radiotherapy group compared with 5.4% (5/93) in the simple surgery group. The 10-year survival rate of DT<50Gy in the radiotherapy group was 52% (13/25), and DT≥50Gy was 78.6% (22/28). Conclusion: Regional lymph node radiotherapy after radical mastectomy in stage II breast cancer, and DT ≥ 50Gy can improve the survival rate of patients.
