不同手术方式联合术后放疗对外阴鳞癌预后的影响

目的对比不同手术方式联合术后放疗对外阴鳞癌的疗效,寻找理想的治疗方法。方法对1980年1月～2005年12月在中山大学肿瘤防治中心经手术治疗并确诊的150例外阴鳞癌进行回顾性分析,生存率计算采用寿命表法,预后比较采用Kaplan-Meier法。多因素预后分析采用Cox回归分析。结果对淋巴结阳性的患者,行外阴广泛切除＋腹股沟淋巴结清扫和（或）盆腔淋巴结清扫术＋放疗、外阴广泛切除＋腹股沟肿大淋巴结切除术＋放疗、外阴广泛切除术＋放疗、外阴广泛切除＋腹股沟淋巴结清扫和（或）盆腔淋巴结清扫术,5年生存率分别为29%、25%、17%、67%（P=0.031）,5年无进展生存率分别为100%、50%、67%、83%（P=0.016）,行外阴广泛切除＋腹股沟淋巴结清扫和（或）盆腔淋巴结清扫术＋放疗者,预后明显好于其余治疗方式患者。对术前检查未发现明显淋巴结肿大的患者,行外阴广泛切除＋腹股沟淋巴结清扫和（或）盆腔淋巴结清扫术,5年生存率（84%vs.46%,P=0.010）和无进展生存率（97%vs.62%,P〈0.001）均明显高于外阴广泛切除术＋放疗患者。结论对中晚期患者,应争取切除原发灶及行腹股沟淋巴结清扫,并术后辅以全量放疗,而对早期外阴癌患者,建议在切除外阴病灶的同时行腹股沟淋巴结清扫术。

The Impect of Different Surgical Methods Combined With Postoperative Radiotherapy on Prognosis of Squamous Cell Carcinoma of the Vulva

Objective By means of comparing the therapeutic effect of different surgical methods combined with postoperative radiotherapy to squamous cell carcinoma of the vulva,to find out the best treatment method.Methods A retrospective analysis was adopted which involves 150 patients with primary squamous cell carcinoma of the vulva treated at Sun Yat-sen University Cancer Center from January 1980 to December 2005.Meanwhile,survival rate was calculated by life table method.Kaplan-Meirer method was used to evaluate ...
