Pelvic exenteration for primary and recurrent vulvar cancer.

Twenty-one patients who underwent pelvic exenteration for primary (n = 8) or recurrent (n = 13) vulvar malignancy at the M. D. Anderson Cancer Center between 1956 and 1989 were evaluated. A posterior exenteration was performed in 12 patients, anterior exenteration was performed in 6, and total exenteration was performed in 3. In patients with primary tumors, radical vulvectomy and inguinal lymphadenectomy were also performed. The median patient age was 57 years. The mean tumor diameters were 5 cm (primary) and 4 cm (recurrent). Infections were the most frequent postoperative complications (n = 15), followed by pulmonary (n = 4) and cardiac problems (n = 3). There were no treatment-related deaths. Five patients required further surgery to correct late postoperative sequelae. Four of eight patients experienced recurrence after treatment of their primary tumor; the recurrences were local only (n = 1), in the inguinal area (n = 2), or local and in the pelvis (n = 1). Nine of the 13 patients treated for recurrent tumors developed a second recurrence; the second recurrences were all within the pelvis, although two also had a distant component. The 5-year survival rates were 70% for patients treated for primary disease and 38% for patients treated for recurrent disease. Pelvic exenteration is indicated for selected patients with advanced vulvar malignancy.
