ST14 and ovarian cancer: In the present study, we tested the hypothesis that TADG-15 may have prognostic value as an ovarian cancer biomarker by investigating the expression of TADG-15 with immunohistochemical techniques in ovarian carcinomas of different stages, grades, and histological types; moreover, we correlated TADG-15 expression with clinicopathological parameters and patients' survival with the use of statistical analyses.
