title: Significance of cyclooxygenase 2 and MDR1/P-glycoprotein coexpression in ovarian cancers.
abstract: Immunohistochemical analysis of prognostic significance of COX-2 and P-gp expression in ovarian cancers was performed on samples originating from 73 tumors. COX-2-positive cases were shown to demonstrate higher expression of P-gp. The studies demonstrated also that, higher P-gp expression was typical for cases which responded poorly to chemotherapy and for cases with shorter progression-free time. Expression of COX-2 predisposed to a more rapid disease progression. The study documented a relationship between COX-2 and P-gp suggesting that COX-2 inhibitors might investigated in clinical trials as a treatment supplementary to chemotherapy of ovarian cancers.
