摘　　要：1964年至1992年收治外阴癌327例,其中行外阴广泛切除加双腹股沟及双盆腔淋巴结清扫95例。95例中46例(48.42%)出现淋巴结转移。对淋巴结转移的有关临床因素和转移部位进行了分析,提示外阴癌淋巴结转移是多因素作用的结果,与原发肿瘤的大小、临床分期、病变部位及病理类型有关。原发肿瘤越大,临床分期越晚,淋巴结转移率越高。本组总的淋巴结转移率为48.42%。Ⅱ、Ⅲ、Ⅳ期的淋巴结转移率分别为23.07%、33.33%及61.80%。同侧淋巴结转移率为25%,对侧为9%,双侧为15.90%,且个别病例可呈跳跃式转移。位于中央部位的肿瘤向两侧淋巴结转移的发生率基本相同,分别为14.88%和12.76%,双侧转移率为17.07%。外阴腺癌、腺鳞癌发生率虽低,但淋巴结转移率高。Objective: To analyze the clinical factors affecting lymph node metastases and the location of the lymph node metastases. Design. A total of 327 patients with vulvar carcinoma treated in our hospital from 1964 to 1992 were included in this study. 95 of them received the radical vulvectomy with bilateral inguinal and pelvic lymphadenectomy. 46 had the lymph nodes metastases. Results: In our study, the total rate of lymph node metastases was 48.42%,For stage Ⅱ, Ⅲ and Ⅳ, the lymph node metastases rate were 23.07%,33.33%,and 61.80% respectively. 25% patients had the ipsilateral, 9% had the controlateral and 15.9% had the bilateral lymph node metastasses. One case had the leap lymph node metastases. Tumor located in the central structure of vulva had the similar incidence of metastases to the left and right site (14.88%//00 and 12.76%). The incidence of the bilateral lymph node metastases was 17.07%. Conclusion:The lymph node metastases of the vulva carcinoma were the results of the multifactors including the primary size, the location of the tumor,clinical stage and the pathology. The bigger and the more advanced clinical stage the tumor was, the higher the lymph node metastases rate was.
