Abstract
Between January 1969, and August 1975, 40 patients with pathologic Stage II carcinoma of the endometrium were treated at the Joint Center for Radiation Therapy. The treatment policy included external and intracavitary irradiation combined with surgery. The majority of patients received 4000 mg/hours of radium exposure using a Fletcher-Suit applicator and 4000 rad whole pelvis external irradiation, followed by hysterectomy and bilateral salpingooophorectomy. Median age of the patients was 61 years (39–88) and the median followup of the patients still alive was 69 months (29–102). Relapse-free 5-year survival corrected for intercurrent disease was 83% and uncorrected, 78%. Overall survival was 80%. Five patients had relapsing disease, three patients failed at distant sites only, one patient died of treatment related complications, and two failed locally and distantly. There were no failures in the pelvis alone. Although the relationship between histologic grade and failure is not statistically significant, there were four failures among the 12 Grade III patients compared to two failures in 27 with Grades I and II. Similarly, 4 of 12 patients with gross cervical involvement developed relapsing disease, but only 2 of 28 failed with microscopic cervical involvement. This treatment policy yields excellent survival and continues to be our treatment recommendation.
