Background : Protein tyrosine kinases (PTKs) such as c-Abl, c-KIT, PDGFR-α and PDGFR-β are key proteins in the regulation of cell growth. In this study, we evaluated the correlations between the expression of c-Abl, c-KIT, PDGFR-α and PDGFR-β and the survival of patients with ovarian cancer. Methods : We performed the immunohistochemistry for 102 patients with ovarian cancer and we retrospectively reviewed the overall and disease free survival and also the response to platinum-based chemotherapy in those patients. Results : The short disease free survival rate was significantly associated with the increased expression of PDGFR-α (p= 0.0459). The short overall survival time in patients with advanced (stage III and IV) ovarian cancer was associated with the overexpression of c-Abl (p=0.0268) and the reduced expression of c-KIT (p=0.0307). On multivariate analysis, the tumor stage and c-Abl maintained their prognostic influence. Meanwhile, none of the four PTK expression patterns predicted the response to the platinum-based chemotherapy. Conclusions : Our data suggest that for patients with advanced ovarian cancer, the overexpression of c-Abl and the reduced expression of c- KIT might be used as poor prognostic factors for overall survival. It is further noteworthy that the tumor stage and c-Abl may be useful in predicting the patients’ survival. Although any of the four PTKs could not predict the response to platinum chemotherapy, the expression of the kinases targeted by tyrosine kinase inhibitor suggests the potential usefulness of imatinib mesylate for the treatment of ovarian cancer.
