title: Prognostic factors in ovarian cancer.
abstract: The improvement in the treatment of ovarian cancer is based on the recognition of the prognostic factors. The 5-year survival rate of 174 patients with epithelial ovarian malignancies after primary operation at the University Department of Obstetrics and Gynecology in Ljubljana and treated with adjuvant therapy at the Institute of Oncology in Ljubljana in the period 1970-1980 was 29.3% (56% for stage I, 36% for stage II, 23% for stage III and 4.5% for stage IV). The amount of residual tumor after the primary operation was prognostically very important (5-year survival in stage III in cases of residual tumor less than 2 cm is 46.6%, in tumor greater than 2 cm only 18.6%). The histological type of tumor, considering the stage, was not important prognostically. On the contrary the grade of differentiation was prognostically very important even in advanced cases: 5 year survival for stage III in cases of well differentiated serous tumors was 61%, in moderately and poorly differentiated cases it was only 7%. Younger patients have better prognosis than older ones, because the tumors are better differentiated, too. Since ovarian cancers are diagnosed too late in 65% of cases in advanced stages, today all efforts should be focussed on early diagnosis, which is probably the only factors that can lead to the dramatic fall of the mortality rate.
