This study was performed to validate a new staging system and support the concept of early regional lymphadenectomy based on this system.
A total of 76 cases from 4 teaching hospitals was reviewed.
Of 24 patients with well or moderately differentiated noninvasive primary tumors 1 had regional metastases compared to 43 of 52 patients with poorly differentiated or invasive tumors.
By classifying disease according to the depth of invasion and degree of differentiation of the primary lesions a high degree of accuracy could be obtained in predicting the likelihood of positive groin nodes. Removing groin nodes that are microscopically positive improves the survival rate over that of delayed lymphadenectomy.
本研究旨在验证一种新的分期系统，并支持基于该系统的早期区域淋巴结清扫的概念。
回顾了4家教学医院的76例病例。
24例高分化或中分化非浸润性原发性肿瘤患者中，1例有区域转移，而52例低分化或浸润性肿瘤患者中有43例有区域转移。
根据原发性病变的浸润深度和分化程度对疾病进行分类，在预测腹股沟淋巴结阳性的可能性方面可获得高度准确性。切除显微镜下阳性的腹股沟淋巴结比延迟淋巴结清扫能提高生存率。
