In subgroup analyses based on pathological type, the Pro variant was significantly associated with an increased esophageal squamous cell carcinoma (ESCC) risk in all four genetic comparison models (ORPro vs. Arg=1.26, 95% CI: 1.08-1.47, POR=0.003; OR Recessive genetic model=1.42, 95% CI: 1.07-1.88, POR=0.015; ORDominant genetic model=1.25, 95% CI: 1.10-1.42, POR=0.001; ORHomozygote model=1.55, 95% CI: 1.14-2.10, POR=0.005), whereas the association between TP53 Arg72Pro polymorphism and esophageal adenocarcinoma risk was still uncertain owing to the limited studies included in this meta-analysis.
