Effective chemotherapy consisting of bleomycin, vincristine, mitomycin C, and cisplatin (BOMP) for a patient with inoperable vulvar cancer.

Combination chemotherapy consisting of bleomycin, vincristine, mitomycin C, and cisplatin (BOMP) was first applied to an inoperable case (57-year-old) with FIGO stage IV (T3N3 + M1B) squamous cell carcinoma of the vulva. After three courses of BOMP therapy, the patient achieved a complete response with few toxic effects and subsequently could undergo radical vulvectomy with bilateral inguinal and pelvic lymphadenectomy. On microscopic examination, only a minute focus of viable squamous cell carcinoma was observed in the vulvar lesion and regional lymph nodes, which was surrounded by fibrotic or necrotic tissues. The patient received a further two courses of BOMP as postoperative chemotherapy. Five courses of BOMP were extremely tolerable and did not require special care. She has been free of disease for 20 months and her present performance status is 0. The encouraging result warrants the use of this combination chemotherapy regimen in other patients with advanced squamous cell carcinoma of the vulva.
