PURPOSE: The purpose of this study was to determine the toxicity, patterns of recurrence, and survival in high-risk endometrial cancer patients treated with whole-abdominal radiation. MATERIALS AND METHODS: All patients with endometrial cancer treated at Northwestern University since 1994 and at Rush University since 1993 were retrospectively reviewed. Patients believed to be at high risk for intra-abdominal recurrence and who received whole-abdominal radiation were reviewed for this study. RESULTS: A total of 30 patients completed whole-abdominal radiation (WAR) and were available for study. The mean and median follow-up was 2.3 and 2.1 years, respectively, with a range of 0.13 to 6.1 years. Seventy-eight percent of the cohort received surgical staging with bilateral salpingo-oophorectomy/total abdominal hysterectomy/lymph node sampling. Forty-seven percent of the patients were found to have serous histology as a component of their tumor. Surgical staging results included 19% stage 1B, 4% stage IC, 8% stage IIB, 37% stage IIIA, 26% stage IIIC, and 7% stage IVB. Two patients had gross residual disease at the completion of surgery. Megestrol acetate (Megace) was used as an adjuvant treatment in 37% of patients, and no cases received initial chemotherapy. All patients received WAR with a mean total dose and dose per fraction of 2620 and 143 cGy, respectively. Twenty-two percent of patients received a para-aortic boost. The mean total pelvic dose was 4956 cGy. Seventy percent of patients received a vaginal cuff boost. Eight percent of patients had grade 3 acute gastrointestinal morbidity, and 4% had grade 4 acute gastrointestinal morbidity. No other grade 3 or greater acute or long-term morbidity was noted. At last follow-up, seven (23%) patients had experienced recurrence. The pattern of first recurrence was 0% in the vaginal cuff, 3% other vaginal, 7% pelvic, 7% upper abdominal, 3% lung, 7% bone, and 7% para-aortic lymph nodes. Ultimate recurrences were similar. At last follow-up, 77% patients had no evidence of disease, 13% were alive with disease, and 10% had died of disease. CONCLUSIONS: Utilizing a conservative total whole-abdominal radiation dose and limited para-aortic nodal boost resulted in very tolerable treatments. The patterns of recurrence and survival in this early report are encouraging.
