| Outline of Final Research Achievements |
Of all of the epithelial ovarian cancers, clear cell adenocarcinoma (CCA) has the worst prognosis. In addition, level of CA125, a conventional marker for ovarian cancer, is relatively low and frequently negative in patients with CCA. Therefore, development of new biomarker is needed to improve diagnosis of CCA. In this study, we analyzed secreted proteins in conditioned media from CCA-derived cell lines by a proteomic approach, and identified a potential biomarker candidate with clinical utilities. Serum level of the identified protein was significantly elevated in CCA patients.
