Abstract
This study aimed to investigate the prognostic value of Ki-67 antigen (Ki-67) in patients with epithelial ovarian cancer. A retrospective review identified a cohort of 78 patients with epithelial ovarian cancer. The association between Ki-67 expression and clinicopathological characteristics and survival was analyzed. High Ki-67 expression was significantly associated with high stage, high histological grade, ascites, and high level of cancer antigen 125 (CA125) (p = 0.011, p = 0.031, p = 0.033, p = 0.004, respectively). In addition, high Ki-67 expression was significantly associated with poor prognosis (p = 0.002), which was further confirmed using a multivariate Cox regression hazards model (Hazard Ratio (HR) = 1.797, 95% confidence interval (CI) = 1.038–3.111, p = 0.026). In conclusion, Ki-67 expression may be a significant prognostic factor in epithelial ovarian cancer.
