| Outline of Final Research Achievements |
We previously found that gene and protein expression of FGFR2 were increased in ovarian clear cell carcinoma (CCC); here, we examined FGFR2 expression in CCC tumor tissues and its correlation with clinical parameters. We also analyzed the effect of an FGFR inhibitor on the growth of CCC cells to investigate whether FGFR2 could be a therapeutic target for this disease. The expressions of FGFR2 were found in 96%of CCC. The 5-year survival rate for patients with a moderate or strong expression of FGFR2 was significantly lower than that for those with an absent or poor expression of FGFR2 (54% vs 79%). Multivariable analysis revealed that FGFR2 expression was independent prognostic factors. The FGFR inhibitor effectively suppressed the growth of CCC cells with induction of G1 cell cycle arrest and down-regulated the expression of phosphorylated Akt and phosphorylated ERK. We conclude that FGFR2 is an important biomarker predictive of patient outcome and is a potential target for CCC.
