Treatment of endometrial carcinoma with high-dose-rate brachytherapy alone in medically inoperable stage I patients.
OBJECTIVE
To review the results of treatment with high-dose-rate brachytherapy alone in 228 patients with stage I endometrial carcinoma who are unfit for surgery.


METHODS
All patients received an exclusive radiation therapy by means of high-dose-rate Iridium 192 intracavitary brachytherapy without additional external beam radiation.


RESULTS
At 5 years, the overall survival rate was 59.7% and disease specific survival 85.4% at 10 years 30.2% and 75.1%. In clinical stage Ia disease specific survival was 88.6% at 5 years and 82.7% at 10 years, in stage Ib 80.2% and 63.4%, respectively (p<0.02). Disease specific survival was not affected by tumor grade or age. The rates of local control are related to the size of the uterus but not to the tumor grading. Intrauterine recurrence occurred in 17.5% but extrauterine pelvic relapse in only 0.4% of patients. The calculated probability of severe complications was 4.6% at 5 years.


CONCLUSIONS
HDR brachytherapy alone achieves excellent disease specific survival rates in patients with medically inoperable stage I endometrial carcinoma.
