ABSTRACT
<p><b>OBJECTIVE</b>In order to investigate the relationship between Glutathione S-transferase M1 (GSTM1) status and the risk on colorectal cancer as well as to detect the related factors to this association.</p><p><b>METHODS</b>A pooled analysis of multilevel Meta-regression was performed to estimate GSTM1 deficiency associated with the risks of colorectal cancer. Then subgroup Meta-regression was undertaken to evaluate the possible relationship between heterogeneity and the related characteristics.</p><p><b>RESULTS</b>The overall pooled odds ratios of colorectal cancer risk associated with GSTM1 deficiency was 1.17 (95% CI 1.08-1.26). Ethnicity, percent of GSTM1 deficiency in population had significant relationships with heterogeneity across the studies (P < 0.05). Results of subgroup Meta-regression showed that GSTM1 deficiency was significantly associated with colorectal cancer risk in ethnic subgroups of Asians, Caucasians and in low level (lower than 50%) of GSTM1 deficiency population (P < 0.05). The respective pooled ORs were 1.14, 1.25 and 1.29.</p><p><b>CONCLUSION</b>GSTM1 deficiency seemed to be a risk factor for colorectal cancer, while interactions on the characteristics of ethnicity, percentage of GSTM1 deficiency in the studied population were related to this association.</p>
