Fifty-one patients were admitted to a single practice at St. Joseph's Hospital between April 1, 1978, and April 1, 1986 with a diagnosis of squamous cell carcinoma of the vulva greater than 1 mm in depth. Five advanced lesions were treated with combinations of radiation and surgery. Four patients had recurrent squamous cell carcinoma. Of 42 patients treated surgically with intention of cure, 14 were treated with complete radical vulvectomy and bilateral inguinofemoral lymphadenectomies, and 28 patients were treated with complete radical vulvectomy and bilateral inguinofemoral lymphadenectomies, and 28 patients were treated in 26 instances with bilateral inguinofemoral lymphadenectomies in one of five different excision patterns individualized to the site of primary tumor. None of the 28 patients have had a recurrence. Five had positive nodes. Eight have died of unrelated causes. Lesions in 25 cases were stage I or II and in three cases they were stage III. Modified radical vulvectomy and bilateral groin dissection is a safe approach for most patients with stage I or II and occasionally even stage III lesions.
