The authors have re-examined 146 patients with stage I and II endometrial carcinoma according to pathological findings. An understaging of FIGO classification of 9.8% and 14.2% in stages I and II, respectively, was found. Also evaluated was the influence of some risk factors (histologic grade, myometrial infiltration) on survival rates which was highly significant for both stages I and II. Surgery was the main form of treatment with an operability rate higher than 90%. The bilateral salpingo-oophorectomy appeared to improve the survival at stage I, 85.8% versus 63.6%, while postoperative external radiotherapy (ERT) seemed to be ineffective.
