[Prognostic significance of tumor cell ploidy in advanced ovarian carcinoma].
A micro-imaging retrospective investigation of tumor cell ploidy using exudates smears from 52 patients with serous ovarian adenocarcinoma (stage III-IV) showed survival in those with diploid tumor to be significantly longer (38 months) than in cases of aneuploid malignancies (16 months). Significant differences in survival versus ploidy, stage, residual tumor size, therapy modality and age were established with the aid of univariate analysis (Caplan-Meyer) of 5-year survival. Multivariate step-by-step regressive analysis (Cox) was carried out on the prognostic significance of such factors as residual tumor size (p=0.013), stage (p=0.019) and tumor ploidy (p=0.035). Further study showed ploidy to be a fully independent factor like any other factors of ovarian carcinoma development.
