The estrogen regulated pS2 protein and the Plasminogen Activator Inhibitor type 1 (PAI-1) have been reported as important tumor parameters both in breast and in ovarian cancer. We analysed the cytosolic concentrations of pS2 in 111 ovarian carcinoma and the cytosolic concentrations of PAI-1 in 104 ovarian cancers by RIA and ELISA. Using a cut-off level of 2 ng/mg protein we found 27% pS2+ tumors. We observed 42% PAI-1+ tumors using a out-off level of 1 ng/mg. We found a statistically significant decline in the pS2 status corresponding with an increase in the PAI-1 status from well to poor differentiation grade. The highest levels of pS2 and the lowest levels of PAI-1 were measured in borderline carcinoma. Significantly higher concentrations of pS2 were measured in mucinous over serous carcinoma. We found no significant correlation between PAI-1 and histologic subtypes, or between pS2 or PAI-1 and estrogen receptor status, progesterone receptor status, age and tumor stage. To conclude, we found pS2 and PAI-1 concentrations to be correlated with the grade of differentiation. A correlation between protein status and histologic subtypes could be observed for pS2 but not for PAI-1.
