• AIM： To evaluate the association of glutathione S-trans-ferase mu （GSTM1） and glutathione S-transferase theta （GSTT1） null genotypes with the risk of gastric cancer （GC） and colorectal cancer （CRC） in a South Korean population. METHODS： We conducted a population-based, large- scale case-control study including 2213 GCs, 1829 CRCs, and 1699 controls. Null and non-null genotypes of GSTM1 and GSI-F1 were determined using realtime PCR. RESULTS： The null genotypes of GSTM1 and GSTT1 were not significantly associated with elevated risk of gastric （OR = 1.070, 95% CI = 0.935-1.224; OR = 1.101, 95% CI = 0.963-1.259, respectively） or colorectal cancer （OR = 1.065, 95% CI = 0.923-1.228; OR = 1.041, 95% CI = 0.903-1.200, respectively）. The frequency of the combined null GST genotype was not different between the two cancer groups and controls. Moreover, smoking, drinking, and age did not modify the association between these genotypes and the risk of gastric or colorectal cancer. CONCLUSION： GSTM1 and GSCI-1 null genotypes were not associated with increased risk of GC or CRC in Koreans.
