1至3个腋窝淋巴结转移乳腺癌根治术后放疗的应用

腋窝淋巴结转移数目为1～3个的早期乳腺癌患者是否需行术后辅助放疗是目前争议的焦点.多个随机研究结果提示,包括全胸壁及相关淋巴结引流区的术后放疗能改善1～3个腋窝淋巴结转移者的局部控制率和生存率.是否行术后放疗取决于肿瘤大小和分期、淋巴结清扫数和淋巴结阳性率、淋巴结包膜外侵犯和脉管瘤栓等因素.最佳放疗方式和患者选择尚有待进一步前瞻性随机对照临床试验来验证.     

1至3个腋窝淋巴结转移乳腺癌根治术后放疗的应用

Nowadays the decision whether to offer early breast cancer patients with 1～3 positive axillary nodes adjuvant radiotherapy is a heated controversy. Results of several randomized trials have shown that post-mastectomy radiotherapy including the whole chest wall and regional lymph node-bearing areas can improve the Iocoregional control and survival rate of patients with 1～3 positive axillary nodes. Tumor size and stage, number of dissected nodes, positive lymph node ratio, extracapsular extension and lymphovascular invasion may determine whether post-mastectomy radiotherapy is needed or not for these patients. The best radiotherapy approach and patients selections should be verified by further prospective randomized control clinical trials.

腋窝淋巴结1～3个转移的乳腺癌根治术后辅助放疗指征探讨

目的 回顾分析412例腋窝淋巴结1～3个转移的乳腺癌根治术后患者的预后因素,探讨术后辅助放疗的指征.方法 用Kaplan-Meier法计算生存率,用Logrank法和Cox模型分别进行单因素和多因素预后分析,分析影响局部复发和远处转移的预后因素.结果 随访率为98.7%.随访满5、10年者分别为215、41例.5、10年总生存率分别为90.0%、81.3%.无、有局部复发的5年总生存率分别为92.9%、69.9%(x2=20.79,P=0.000).5、10年局部复发±远处转移率分别为10.7%、18.6%.多因素分析显示T2期,≥2个腋窝淋巴结转移,雌、孕激素受体均阴性为影响局部复发的预后因素.含0～1、2～3个预后因素的10年局部复发率分别为3.9%、36.9%(x2=20.64,P=0.000).多因素分析显示局部复发、阳性淋巴结转移率＞25%为影响远处转移的预后因素,无、有局部复发的5年远处转移率分别为9.7%、36.6%(x2=16.34,P=0.000).结论 对腋窝淋巴结1～3个转移的乳腺癌根治术后患者且含2～3个影响局部复发的预后因素者建议行术后辅助放疗.     

T1～T2期伴1～3个腋窝淋巴结转移乳腺癌患者改良根治术后放疗的作用

目的 回顾性分析370例T1～T2期、腋窝淋巴结转移数为1～3个乳腺癌患者改良根治术后的治疗结果,探讨放疗的作用.方法 用Kaplan-Meier法计算生存率,分析放疗对生存率和复发率的影响,同时分析对未放疗患者复发率有影响的临床病理因素.结果 中位随访时间为50个月(9～91个月).全组患者的5年无局部区域复发率为91.0%,总生存率为85.4%.放疗显著提高5年无局部区域复发生存率(100%和89.5%;x2=5.17,P=0.023),对总生存率无影响.对319例未行放疗患者的单因素分析显示T分期、腋窝淋巴结阳性数、C-erbB-2和PR状态是预测无复发生存率的有意义因素.结论 T1～T2期且腋窝淋巴结转移数1～3个乳腺癌患者改良根治术后,放疗显著降低局部复发率,但对总生存率无影响.T分期、腋窝淋巴结阳性数、C-erbB-2和PR状态是预测元复发生存率的有意义因素.
