Abstract:
:Elevated levels of expression of the urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1 have shown to be related to poor prognosis in a variety of cancer types. In the present study, cytosolic levels of uPA and PAI-1 were determined with enzyme-linked immunosorbent assays in cytosols prepared from 244 human ovarian tissues of different histological sub-types. Both uPA and PAI-1 were significantly associated with the malignant progression of ovarian tissues; the levels were increased going from normal tissue, via benign and borderline adenomas, to primary and metastatic adenocarcinomas. For the 90 patients (34 early-stage and 56 patients with advanced disease) from whom the primary adenocarcinoma tissues were examined, uPA and PAI-1 levels were evaluated for their association with clinicopathological parameters and with progression-free and overall survival. Neither uPA nor PAI-1 were significantly associated with the age of the patient, FIGO stage, tumor grade, tumor rest, the presence of ascites, or with progression-free or overall survival. On the other hand, age, FIGO stage/tumor rest and the presence of ascites, were significantly related to the length of both progression-free and overall survival in univariate analyses. Tumor grade was of prognostic significance in the analysis for progression-free survival, but not for overall survival. After adjustment for FIGO stage/tumor rest, only age retained its prognostic significance, in the analysis for progression-free survival and in that for overall survival.
