Résumé
Purpose
: From 1967 to 1986, 250 patients with endometrial carcinoma were treated with exclusive radiation therapy: 178 with a minimal follow-up of 5 years and 146 with a minimal follow-up of 10 years. The mean age was 68 years, ranging from 53 to 82 years, and the median follow-up duration was 8.5 years (minimum of 5 years and maximum of 23 years).
Methods and Materials
: All the patients received an external beam radiation treatment (45 Gy in 4.5 to 5 weeks to the whole pelvis) followed by a utero-vaginal brachytherapy.
Results
: At 5 years, the overall survival rate was 58.4% and the disease-free survival rate 55%. At 10 years the overall survival rate was 46.5% and the disease-free survival rate was 45.2%. Without considering deaths from intercurrent disease, the overall survival rate was 76.5% and the disease-free survival rate was 65.8% after 5 years, and 68% and 66%, respectively, after 10 years. The causes of failure were: isolated metastasis: 7.3%, local failure: 24.1% (4.5% with and 19.6% without concomittent distant metastasis). The rates of local control and of survival are related to the tumor stage and the tumor grade.
Conclusion
: The results are discussed according to the literature data and show the ability of exclusive radiation treatment to achieve acceptable results and to be a curative alternative for treating endometrial cancer providing that a correct external beam radiation therapy and a suitable brachytherapy are fulfilled.
