Analysis for ethnicity and smoking for each of the investigated polymorphisms showed that some genotypes can have a predictive value for susceptibility to CRC, at least those that demonstrate statistically significant ORs either for the combined mixed population of Kazakhstan or for both main ethnic groups separately (Kazakhs and Russians): TP53 Pro72Pro homozygous (for Kazakh-OR = 3.40, 95 %CI = 1.63-7.06, χ (2) = 11.35, p < 0.003; for Russian-OR = 4.69, 95 %CI = 2.53-8.66, χ (2) = 53.19, p < 0.0001) and GSTM1 deletions (for Kazakh-OR = 2.30, 95 %CI = 1.21-4.40, χ (2) = 8.42, p < 0.01; for Russian-OR = 1.64, 95 %CI = 1.01-2.66, χ (2) = 7.82, p < 0.02).

Further, the GSTM1*0/*0 genotype is a significant risk factor for gastric (odds ratio = 4.1; 95% confidence interval: 1.2-14.5) and colorectal cancers (odds ratio = 3.8; 95% confidence interval: 1.7-8.5); on the other hand, CYP1A1*2A and CYP2E1*6 alone are not significantly associated with GI cancer development, although CYP1A1*2A was more frequent among patients.
