Abstract: Objective To assess the association between glutathione S-transferase T1 (GSTT1) gene and the susceptibility of colorectal cancer among Chinese population. Methods Clinical controlled trials of the association between GSTT1 and the susceptibility of colorectal cancer among Chinese population were searched in PubMed, EMBase, Cochrane Library, China Biology Medicine disc, VIP database, China National Knowledge Infrastructure and Wanfang database. According to the inclusion and exclusion criteria, data extraction and quality assessment were done by two researchers independently. Outcomes were pooled with RevMan 5.1. Results 326 studies were found and 10 clinical controlled trails including 2 983 cases of colorectal cancer and 4 386 cases of healthy objects were included in this analysis. The results of Metaanalysis showed that the lack of GSTT1 gene is associated with colorectal cancer susceptibility (RR=1.11, 95%CI: 1.061.17, Z=4.26, P<0.000 1). Conclusion The loss of GSTT1 increase the risk of colorectal cancer among Chinese population.
