Analysis adjustment by age showed that the patients with presence of G/G genotype for the rs3826392 variant have a protective effect for TNM III+IV stages (OR=0.45; 95% CI=0.23-0.87, P =0.027); while, individuals with the T/T genotype for the rs3809728 variant, have a marginally significant difference for TNM III+IV stages (OR=2.28; 95% CI=1.03- 5.03, P =0.058) ( Table 4 ).
