description The P53 codon 72 polymorphism has been identified as a critical biomarker in modifying the risk of nasopharyngeal cancer (NPC). Many studies have investigated the association between the polymorphism of P53 codon 72 and NPC risk; however, the findings across the published studies are inconsistent and inconclusive. To acquire a more precise assessment for this association, we conducted an updated meta-analysis. The PubMed, Embase, Web of Science, and Wanfang databases were searched for relevant case–control studies. Totally, seven independent publications with 1,133 cases and 1,678 controls were retrieved. The pooled odds ratio (OR) with corresponding 95 % confidence interval (95 % CI) was calculated. Increased risk of NPC was observed among individuals carrying the variant allele and genotypes of P53 codon 72 (OR Pro vs. Arg  = 1.32, 95 % CI 1.18–1.47, P OR
