A retrospective analysis of 88 patients with vulvar cancer treated by radical vulvectomy and groin lymphadenectomy from July, 1958 to December, 1990 is presented. 88 cases are divided into two groups based on different operative methods: the enbloc group (25 cases) and the non-enbloc group (63 cases). No significant statistic differences are found in the 5-year survival rates (76.0% vs 79.8%) and the complications (erysipelas, lower extremity edema) between the two groups. The wound healing time is 14.4 days shorter in the non-enbloc group than enbloc group. Factors such as clinical staging, metastasis to the inguinal lymph nodes and histopathological classification are also investigated for correlation with the prognosis.
