Genetic association between p53 codon 72 polymorphism and risk of cutaneous squamous cell carcinoma

Abstract

This study was designed to obtain a conclusive result about the relevance of p53 codon 72 polymorphism to the risk of cutaneous squamous cell carcinoma (SCC). We performed an updated meta-analysis of 3,792 subjects (1,349 cancer cases and 2,443 controls) to summarize the data available for p53 codon 72 polymorphism and SCC risk. The association was estimated by odds ratios (ORs) with 95% confidence intervals (CIs). The meta-analysis showed no statistical significance for SCC risk associated with any of the genetic models of p53 codon 72 polymorphism. The analyses by ethnic subgroup also failed to produce significant associations. This study suggests that p53 codon 72 polymorphism does not appear to represent a significant susceptibility factor for SCC in Caucasians.
