Abstract

Accumulating evidence suggests the CASP gene family is important in the development of carcinogenesis. These genetic polymorphisms have been extensively investigated as a potential risk factor for cancer, but results have been inconclusive. This Human Genome Epidemiology (HuGE) review and meta‑analysis was performed to investigate the associations between CASP‑1, ‑2 and ‑5 and cancer risk. A literature search of Pubmed, Embase, Web of Science and CBM databases was conducted from inception through September 1st, 2012. Four case‑control studies with a total of 1,592 cancer cases and 1,833 healthy controls were included in the present meta‑analysis. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. Five polymorphisms were examined, including rs501192 (G>A), rs4647297 (C>G), rs507879 (T>C), rs3181320 (G>C) and rs523104 (G>C). Meta‑analysis results showed that the rs3181320*C allele/carrier were associated with increased risk of various types of cancers (OR=1.26; 95% CI, 1.04‑1.54; P=0.020 and OR=1.33; 95% CI, 1.00‑1.75; P=0.047, respectively). However, similar associations were not found in the rs501192, rs4647297, rs507879 and rs523104 polymorphisms (all P>0.05). Results from the current meta‑analysis suggest that the rs3181320*C allele/carrier in CASP‑5 gene are potential risk factors for cancer.
