Four hundred fifteen patients who had invasive carcinoma of the vulva were treated with primary surgery from July 1, 1955, through June 30, 1989. Three hundred seventy-six (90%) of the patients had squamous carcinoma. Two hundred fourteen patients (52%) had radical vulvectomy with inguinofemoral lymphadenectomy. Twenty-four patients (6%) underwent radical vulvectomy with pelvic exenteration for advanced disease, and 55 patients (13%) had nonradical operations. The remaining 122 patients (29%) underwent radical vulvectomy, inguinofemoral lymphadenectomy, and pelvic lymphadenectomy. The primary morbidity was associated with lymphedema (8.6%) and groin wound breakdown (54%). No intraoperative deaths occurred among the 415 patients treated surgically, but there were 17 deaths (4%) within 28 days of operation. The absolute 5-year survival rate was 85% in patients with negative inguinofemoral lymph nodes and 39% when these lymph nodes were positive for metastatic carcinoma. The overall absolute 5-year survival rate was 67%.
