title: Primary radiation therapy for medically inoperable patients with endometrial carcinoma--stages I-II.
abstract: Surgery with or without adjuvant radiation is the established method of treating patients with Stage I and II adenocarcinoma of the endometrium. However, patients who are poor operative risks must be treated with radiation therapy only. We report on 73 such patients treated at the University of North Carolina between 1969 and 1980. All patients had an adenocarcinoma of the endometrium; 41 were FIGO Stage I, 32 Stage II. The minimum follow-up period was 4 years. Life table analysis shows a disease-free survival of 72% at 3 years and 57% at 5 years for Stage I patients. There was a strong correlation between histologic tumor grade and survival in these patients; the 5-year survival for grade 1 was 72%, for grade 2 59%, and for grade 3 31%. The difference between G1 and G3 is significant at the p = .045 level. Coexisting medical conditions were responsible for 12 deaths; almost as many as the 16 cancer-related deaths. Stage II patients have an actuarial disease-free survival of 36% at 3 years and 26% at 5 years, significantly worse than Stage I patients (p = .029 at 3 years). Failures were seen in 16/41 (39%) Stage I and 19/32 (59%) Stage II patients; 29/35 (83%) of these recurrences had component of local/pelvic failure and 15/35 (43%) of the recurrences were local/pelvic only. Specific suggestions on how to improve local therapy for these patients are presented.
