Eighty-five patients with clinical State I endometrial carcinoma were reviewed: 81% of patients had either pre-operative or post-operative radiotherapy (RT). The incidence of deep myometrial invasion (outer 1/3 of thickness) of pre-op RT vs. post-op RT group was 6% and 28% respectively; the pre-op irradiation seemed to alter the depth of myometrial invasion. Eleven patients (13%) developed recurrences: 9 of these patients (82%) had recurrences in the extrapelvis. The incidence of extrapelvic recurrence of patients with Grade 3 tumors was 29% 4/14); those with deep myometrial invasion was 33% (4/12). The overall 5 year survival and complication rate was 89% and 4% respectively: these results were comparable between pre-op RT and post-op RT groups. However, post-op RT offers the advantage of accurate surgical-pathologic staging and optimal individualization of adjuvant therapy. In addition, those who have deep myometrial invasion and/or Grade 3 tumors may require systemic therapy in view of high incidence of distant failures.
