Several studies inspected the relationship between caspase‐3 (CASP3) polymorphisms and the risk of several human cancers, but the findings remain controversial. We conducted a meta‐analysis aiming to inspect the association between CASP3 rs1049216 T>C, rs12108497 C>T, rs4647603 G>A, rs4647602 C>A, rs6948 T>G, rs2705897 A>C, and rs113420705 G>A polymorphisms and cancer risk. Eligible studies were recognized by searching the Web of Science, PubMed, Scopus, and Google Scholar databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to quantitatively evaluate the association between each polymorphism of CASP3 and cancer risk. The rs4647603 variant significantly increased the risk of cancer in an overdominant (OR, 1.44; 95% CI, 1.03‐2.01; P = 0.03; AG vs AA+GG) inheritance model. Regarding the rs4647602 variant, the findings revealed that this variant was associated with protection against cancer in homozygous codominant (OR, 0.67; 95% CI, 0.56‐0.80; P < 0.00001; AA vs CC), dominant (OR, 0.84; 95% CI, 0.73‐0.96; P = 0.009; AC+AA vs CC), recessive (OR, 0.70; 95% CI, 0.61‐0.79; P < 0.00001; AA vs AC+CC), and allele (OR, 0.81; 95% CI, 0.75‐0.88; P = 0.00001; A vs C) models. The findings suggested that the rs2705897 variant significantly decreased the risk of cancer in heterozygous codominant (OR, 0.80; 95% CI, 0.67‐0.94; P = 0.009; AC vs AA), dominant (OR, 0.81; 95% CI, 0.69‐0.95; P = 0.009; AC+CC vs AA), overdominant (OR, 0.80; 95% CI, 0.68‐0.95; P = 0.01; AC vs CC+AA), and allele (OR, 0.85; 95% CI, 0.74‐0.97; P = 0.02; C vs A) models. The results did not support an association between CASP3 rs1049216 and rs6948 polymorphisms and cancer risk. In summary, the findings of this meta‐analysis support an association between CASP3 polymorphisms and cancer risk. Larger and well‐designed studies are desired to evaluate these associations in detail.
