Melanoma of the vulva: an update.
During the time interval 1950 through 1980, 48 patients having a mean age of 60.2 years were treated primarily for melanoma of the vulva. In all but one patient, a surgical therapeutic approach was selected, including 40 modified Basset procedures and 23 pelvic lymphadenectomies. The 5-year survival rate of the eligible population was 54%. Although surgical staging according to the classification established by the International Federation of Gynecology and Obstetrics (FIGO) was of minimal value, microstaging, using Clark's and Breslow's stratifications for assessing dermal penetration, was of prognostic significance. Ten-year survival rates associated with Clark's level II, III, IV, and V tumors were 100, 83, 65, and 23%, respectively. Histologic growth patterns (5-year survival rates of 71 and 38% for superficial spreading and nodular melanomas, respectively) and groin nodal metastasis were cogent prognostic factors and indirectly were related to depth of local tumor invasion. Likewise, assessment of treatment failures demonstrated a positive correlation between recurrences (specifically at distant sites) and Clark's level of melanocytic penetration. Because of the unacceptably high (32%) local treatment failure rate despite radical vulvar resection, treatment modifications for vulvar melanoma are imperative.
