OBJECTIVE: Kinesin family member 14 (KIF14) is a mitotic kinesin and plays an important role in tumor progression. KIF14 overexpression has been observed in multiple cancers and has been correlated with a poor prognosis. However, its protein expression and prognostic significance in epithelial ovarian cancer (EOC) remain unclear. In this research, we aimed to explore the relationship of KIF14 expression with clinicopathological parameters and prognosis in EOC. MATERIALS AND METHODS: In this study, we measured KIF14 expression in 170 EOC carcinoma tissue samples with immunohistochemistry and correlated these data with clinicopathological characteristics. RESULTS: The expression of KIF14 in EOC tissues was significantly higher than that in normal tissues. Furthermore, KIF14 expression was significantly associated with metastasis (p = 0.047), histological type (p = 0.001), Ki67 expression (p = 0.004) and residual tumor (p = 0.038). Also, Kaplan-Meir survival curves showed that a high level of KIF14 expression was a predictor for worse PFS (p = 0.013) and OS (p = 0.009) in patients with EOC. CONCLUSIONS: KIF14 expression may be associated with poor prognosis, suggesting that it has potential value as an effective prognostic predictor in EOC patients.
