title: Trends in the operative management of invasive squamous carcinoma of the vulva at Indiana University, 1974 to 1988.
abstract: From January 1974 to March 1988, 150 patients with primary invasive squamous cell carcinoma of the vulva underwent surgery at Indiana University. There has been a trend toward more conservative surgical management of this disease. To determine the impact of this trend on clinical outcome, cases were divided into three groups according to date of operation: group I, 1974 to 1978; group II, 1979 to 1983; and group III, 1984 to 1988. Overall, 80 patients had en bloc radical vulvectomy and groin dissection, 20 had modified radical vulvectomy and bilateral groin dissection through three separate incisions, and 36 had modified radical vulvectomy and unilateral superficial groin dissection. Fourteen patients had other operations. Forty-two patients (27.3%) had radiotherapy in addition to surgery. Among the three groups, there were no differences when mean age, International Federation of Gynecology and Obstetrics stage distribution (1988 system), mean lesion size, mean depth of invasion, or grade distribution were compared. A significant trend toward more conservative surgical therapy was observed. En bloc radical vulvectomy was performed in 77.4% of group I patients, 71.1% of group II patients, and 35.8% of group III patients (p less than 0.001). Mean days of hospitalization were also reduced significantly. Group I had a mean stay of 30 days, group II had a mean stay of 23 days, and group III had a mean stay of 11 days (p less than 0.001). Mean operative blood loss (group I, 754.8 ml; group II, 620.0 ml; group III, 393.6 ml; p = 0.03), mean units of blood transfused (group I, 1.4 units; group II, 1.3 units; group III, 0.4 units; p less than 0.01), and mean hours of operating time (group I, 3.7 hours; group II, 3.7 hours; group III, 3.2 hours; p = 0.02) were also reduced.
