Abstract

Introduction: Ovarian Cancer (OC) is the most lethal cancer among gynecological malignancies. In the last years, several studies clarified that OC is characterized by different clinical entities that share only the anatomic site. The aim of this review is the evaluation of Ki-67 and p53 as prognostic factors in OC.
Methods: By searching Pubmed and abstracts from major cancer meetings, we selected clinical trials within the timeframe 2000-2016. We evaluated all data retrievable and we performed a pooledanalysis by random effect model. The endpoints were the Overall Survival (OS) in terms of Hazard Ratios (HRs) of survival outcomes.
Results: We observed a more severe outcome for patients over-expressing Ki-67. However, the overall data of our PFS meta-analysis did not reach the statistical significance (HR 1.98 CI 0.60-6.52, p=0.26). The indirect comparison of p53 studies, here reported, highlighted a possible correlation between patients OS and p53 status. Conclusions: We hypothesize that both Ki-67 and p53 alterations retain a prognostic role in terms of OS in OC.
