One hundred seventy-two cases of patients with squamous cell cancer of the vulva treated at the University of Michigan Medical Center from 1975 to 1988 are reported. The mean age was 66 years with a range of 21 to 101 years. The distribution by stage included Stage I, 65; Stage II, 44; Stage III, 50; and Stage IV, 13 patients. Groin node dissections performed on 145 patients showed negative nodes, 58%; unilateral positive nodes, 28%; and bilateral positive nodes, 14%. The distribution of patients with positive nodes was influenced by stage: Stage I, 14%; Stage II, 23%; Stage III, 72%; Stage IV, 92%. The overall cumulative 5-year survival was 71% and this was significantly influenced by stage of disease: Stage I, 94%; Stage II, 91%; Stage III, 36%; Stage IV, 26%. Stages I/II and III/IV were combined for analysis. In Stages I/II, survival was significantly influenced by tumor grade while size, patient age, and lymph node status did not influence survival. In Stage III/IV, survival was significantly influenced by tumor size, node status, and number of positive nodes while grade, patient age, and tumor location did not influence survival. Squamous cell cancer of the vulva is effectively treated with radical surgery but advanced-stage disease with regional metastases significantly alters survival.
