title: Endometrial carcinoma stage I--comparison of two different treatment regimes--evaluation of risk factors and its influence on prognosis; suggested step by step treatment protocol.
abstract: Two hundred twenty-four patients with stage I endometrial carcinoma were treated between the years 1964 and 1978. One hundred and fifteen patients were classified as clinical stage Ia (51.3%) and 109 patients as clinical state Ib (48.7%). For stage Ia the standard treatment protocol was total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH + BSO). In stage Ib disease, preoperative irradiation was performed followed by TAH + BSO after an interval of 4 to 6 weeks. Postoperative irradiation to the pelvis and vaginal vault was given when extrauterine spread was found and in cases of myometrial penetration beyond the inner one-third of the myometrium. At evaluation in May 1983, the rate of disease recurrence in stage Ia was 20% and in stage Ib 9.1%. Five-year survival in stage Ia was 77.3% and 72.4% in stage Ib. Preoperative irradiation was found justified for G3 disregarding the clinical stage, therefore the approach of routine preoperative irradiation in stage Ib is not recommended. The uterine cavity depth was found to be an inaccurate prognostic parameter. According to the data collected in our material the histological grade and myometrial invasion are much better prognostic parameter and should be taken into consideration while planning the treatment regime.
