ABSTRACT
Cytoplasmic localization of apurinic/apyrimidinic endonuclease 1 (APE1) correlates with different tumorigenic processes and poor prognosis in several cancer types. However, rare investigation into the prognosis value of cytoplasmic localization of APE1 was provided in ovarian cancer. The present study examined for the first time the cytoplasmic localization of APE1 in epithelial ovarian cancer (EOC) by immunohistochemistry. The relationship between cytoplasmic localization of APE1 and clinicopathological parameters, as well as the correlation between cytoplasmic localization of APE1 and prognosis, was investigated. We found that cytoplasmic positivity was significantly higher in EOCs with low tumor differentiation (P = 0.002) and was significantly higher in advanced Federation International of Gynecology and Obstetrics (FIGO) stage (III + IV) patients compared to that in early FIGO stage (I + II) patients (40.7% vs. 11.8%; P = 0.002). No significant difference was observed in APE1 pattern referring to age, tumor size, family history, histological type, ascites, and lymphatic metastasis (P > 0.05). In addition, a lower survival rate was found in patients with cytoplasmic positive localization of APE1 compared to that in patients with cytoplasmic negative localization (P < 0.05). All these findings suggest that cytoplasmic localization of APE1 is associated with tumor progression and might be a valuable prognostic marker for EOC.
