[Histologic type and tumor maturity as prognostic factors in malignant epithelial tumors of the ovary].
A retrospective pathological analysis of 664 patients with malignant ovarian epithelial tumors of coelom epithelium origin was performed. In 93 cases (14%) proliferative tumors were found. Out of the remaining 571 cases a group of 311 cases with the five-year survival in the period 1965-1980 was singled out (39.9% invasive and 98% proliferative tumors). The clinical staging of the illness is the most important prognostic factor. In the clinical stage I the five-years survival was 78.8%, the difference being statistically not significant in relation to the histological maturity of the tumors. For any further clinical stage the five-year rate of survival decreased by about 30%. In the clinical stages II, III and IV survival statistically significantly differed (p less than 0.01) with regard to the histological grade of maturity I, whereas the survival was almost the same in cases with moderately or poorly differentiated tumors. Regardless of the clinical stage of the illness, the five-year survival rate for histological grade I was 71.8%, for grade II 24.5% and for grade III 20.4%. According to the histological type of the tumors, the best prognosis is for mucinous cancers, where the five-year rate of survival was 51.4%, and the worst for undifferentiated (13.3%) and clear-cell cancers (16.7%).
