Individualization of treatment for stage I squamous cell vulvar carcinoma.
Of 177 cases of invasive squamous cell vulvar cancer seen at the University of California at Los Angeles and the City of Hope National Medical Center from 1957 to 1980, 84 (47.5%) had stage I disease. Seventy-seven patients with stage I disease (91.7%) had stromal invasion of 5 mm or less. Correlation between lymph node status and depth of invasion was as follows: 1 mm or less, none of 34 (0%); 1.1 to 2 mm, two of 19 (10.5%); 2.1 to 3 mm, two of 17 (11.8%); 3 to 5 mm, one of seven (14.3%); more than 5 mm, three of seven (42.9%). Fifty-six patients had radical vulvectomy for the primary lesion, and 28 had more conservative excision, but the incidence of local invasive recurrence (4%) was the same in each group. None of 58 patients treated with inguinal-femoral lymphadenectomy developed a groin recurrence, but three of 26 patients (11.5%) who had omission or modification of inguinal-femoral lymphadenectomy died with groin recurrence within 12 months. These data suggest that although some modification of the standard radical vulvectomy is appropriate for the primary lesion in patients with stage I disease, patients with greater than 1 mm of stromal invasion require at least an ipsilateral inguinal-femoral lymphadenectomy.
