Abstract
Fifty patients with advanced (stage III or IV) ovarian carcinoma were followed-up until the date of their death or their fifth year of survival. Prognostic factors, including those currently in use, as well as ploidy and proliferation, chemoresistance testing and hormone receptor levels of the tumours were analysed for predictive value and independence from each other. In the univariate analysis, only stage, residual tumour, second-look status, chemoresistance, ploidy and proliferation were significantly correlated with survival. After being tested in a multivariate Cox regression model, however, only the results of chemoresistance testing at initiation of therapy, and second-look status at a later point, retained prognostic significance. Within the group of patients with a positive second-look, i.e., with the worst prognosis, the chemoresistance test was still able to discriminate between two subgroups with significantly different survival.
