Results of radiotherapy in recurrent endometrial carcinoma: a retrospective analysis of 51 patients.
A retrospective analysis was performed of 51 patients with locoregional recurrence of endometrial carcinoma, treated by radiotherapy between 1959 and 1986. There were 17 patients (33%) with isolated vaginal recurrence, 12 patients (24%) with vaginal recurrence with pelvic extension, 7 patients (14%) with pelvic recurrence only, and 15 patients (29%) with simultaneous locoregional and distant failure. Eighty percent of the recurrences occurred within 3.5 years from primary treatment; time to relapse was shorter in patients with advanced-stage, high-grade malignancy at original diagnosis. Locoregional control was achieved in 18 patients (35%). Complete tumor regression in the vagina, irrespective of extravaginal pelvic disease status or distant metastasis, occurred in 28 of 34 patients with vaginal involvement (82%). The 5- and 10-year overall actuarial survivals for all patients were 18 and 12.5%, respectively. The 5- and 10-year progression-free survivals of patients with isolated vaginal recurrences were 40% and 29%, respectively; the 5-year progression-free survival of patients with vaginal recurrence with pelvic extension was 20%. There were no survivors beyond 1.5 years among patients with pelvic recurrence (p = 0.02). All patients with simultaneous locoregional and distant failure were dead by 3.5 years. Stage at original diagnosis, time to relapse from primary treatment, histologic pattern, and grade of malignancy were prognosticators of survival. Five patients (10%) developed a total of ten radiation-related sequelae.
