In order to make a comprehensive assessment of the potential association between interleukin-4 (IL-4) -589C>T and colorectal cancer (CRC) susceptibility, we conducted a meta-analysis of six epidemiological studies, which included 1,317 CRC patients and 1,659 controls. The data showed that IL-4 -589C>T was not associated with increased CRC risk in the overall population. In the subgroup analysis of IL-4 -589C>T, the results did not change when the analyses were restricted to race. Based on this meta-analysis, we conclude that IL-4 -589C>T may be not a risk factor for CRC development. Further research is needed to assess possible gene–gene or gene–environment–lifestyle interactions on CRC.
