Pathological prognostic factors in a series of 137 stage I TNM/UICC endometrial carcinomas.
OBJECTIVE
We report on the long-term results of combination surgery-radiotherapy in cT1 carcinoma of the endometrium according to prognostic factors.


METHODS
From 1974 to 1993, 130 women suffering from cT1Nx-O Mo endometrial carcinoma, underwent surgical resection. The median age was 62 years. Thirteen received pre-operative irradiation, two pre-operative brachytherapy followed by post-operative external irradiation and 115 patients (88.35%) underwent post-operative irradiation therapy by brachytherapy or external beam irradiation.


RESULTS
The median follow-up is 67 months. Overall and specific survival rates for patients with cT1pT1 tumours were 71.1 and 85% at 10 years. For overall survival, lymph node invasion was the most powerful prognostic factor in the multivariate analysis (P = 0.02). If lymph node invasion is not taken into account, the WHO histological grade exerts a significant prognostic impact (P = 0.001).


CONCLUSIONS
For stage cT1 endometrial carcinoma, primary surgery allows radiotherapy to be adjusted according to the WHO histological grade, myometrial invasion and the pelvic lymph node status.
