ABSTRACT
The dysfunction of p53 is the most common genetic alteration in human cancer. A variety of studies have investigated the clinicopathologic correlation of p53 and its impact on patient survival in different types of cancer. For extrahepatic bile duct cancer (EBDC), however, the results were limited and conflicting. In this study, we performed an investigation to confirm whether there was a correlation between p53 status and some routine parameters. To further observe the impact of p53 on the survival of EBDC patients, a meta-analysis based on published studies was conducted. Candidate studies were searched from PubMed, EMBASE, and ISI Web of Science. Our results demonstrated that there were significant correlations between p53 expression and some clinicopathological parameters. Furthermore, the pooled results of the meta-analysis showed that the combined hazard ratio (HR) estimate for overall survival (OS) was 1.53 (95% CI, 1.10-2.14) and 1.23 (95% CI, 0.93-1.75) in univariate and multivariate analysis, respectively. In conclusion, the high level of p53 appears to be an effective prognostic factor to OS of EBDC patients. However, some limitations unavoidable in this meta-analysis and problems of previous p53 studies in EBDC mean that further studies are necessary before significant conclusions can be made.
