    Abstract:
    Histopathologic factors were investigated in the data for ninety-one patients with endometrial carcinoma who were treated surgically. Each of these subjects was reclassified according to the new FIGO surgical criteria (1989) for stages and the relationship between the new classifications and the prognosis of patients was analyzed. One third of the patients (24/72) with clinical FIGO stage I (1983) had extracorporeal spread of the disease and these cases were reclassified as surgical stages II and III. Among clinical stage Ib patients there were many more with extracorporeal spread than among those in clinical stage Ia (p less than 0.005) although there was no difference between the histopathological characteristics (histologic grade, myometrial invasion, cervical involvement, adnexal involvement and pelvic lymph node metastasis) of the stage Ia and Ib groups. Univariate survival analysis revealed that the histologic grade (p less than 0.05), myometrial invasion (p less than 0.05), cervical involvement (p less than 0.005) and pelvic lymph node metastasis (p less than 0.005) correlated with the patient's prognosis. Multivariate survival analysis with the proportional hazard regression model showed that cervical involvement (p = 0.05) and the new stage classification (p = 0.03) correlated significantly with the prognosis. The cumulative 5-year survival rate by clinical stage (1983) was 87% for stage I (Ia: 96%, Ib: 80%) and 72% for stage II, between which no significant difference was determined. The survival rate for stage III was not calculated because there was only one case with stage III disease in this study.(ABSTRACT TRUNCATED AT 250 WORDS)
