Prevention of vaginal recurrence of stage I endometrial adenocarcinoma with postoperative vaginal radiation.
From 1975 to 1982 a prospective study was conducted at Roswell Park in 68 patients (group 1) for surgical stage I endometrial cancer, grade 1 or 2, and less than 50% myometrial invasion. These patients were treated by total abdominal hysterectomy, bilateral salpingo-oophorectomy, and postoperative vaginal radium. With median follow-up of 4.8 years, there has not been a single vaginal recurrence. This treatment plan was based on a prospective study at the same institute from 1958 to 1967, which compared patients with stage I endometrial cancer treated by hysterectomy alone, preoperative radium followed by hysterectomy, and hysterectomy followed by postoperative radium. In addition, 19 patients (group 2) were evaluated as to their initial treatment after their referral to Roswell Park with vaginal recurrence after surgical treatment for stage I endometrial cancer. None of these patients were treated initially with postoperative vaginal radium after hysterectomy. Based on the zero incidence of vaginal recurrence in 117 patients with FIGO stage I endometrial cancer, the estimated five-year survival rate of 97.2% for the group 1 patients, and the actuarial five-year survival of 95% in the 1958 to 1967 prospective study, it is concluded that primary surgery should be followed by postoperative vaginal radium (cesium) in those patients with stage I endometrial cancer, grade 1 or 2, with less than 50% myometrial invasion.
