Invasive carcinoma of the vulva. Changing trends in surgical management

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%.
