Aim.The aim of our study was to assess whether selected single nucleotide polymorphisms of CYP1A1 and 2E1,GSTM1,GSTT1,and SULT1A1 influence susceptibility towards HCC,considering their interaction with cigarette smoking.Methods.We recruited HCC cases and controls among patients admitted to the hospital "Agostino Gemelli,"from January 2005 until July 2010.Odds ratios (OR) of HCC were derived from unconditional multiple logistic regression.Gene-gene and gene-smoking interaction were quantified by computing the attributable proportion (AP) due to biological interaction.Results.The presence of any CYP2E1 5B variant allele (OR:0.23;95% CI:0.06-0.71) and CYP2E1 6 variant allele (OR:0.08;95% CI:0.01-0.33) was inversely related to HCC.There was a borderline increased risk among carriers of combined CYP1A1 2A and SULT1A1 variant alleles (OR:1.67;95% CI:0.97-3.24). A significant biological interaction was observed between GSTT1 and smoking (AP = 0.48; 95% CI: 0.001-0.815), with an OR of 3.13 (95% CI: 1.69-5.82), and borderline significant interaction was observed for SULT1A1 and smoking (AP = 0.36; 95% CI: -0.021-0.747), with an OR of 3.05 (95% CI: 1.73-5.40). Conclusion. CYP2E1 5B and CYP2E1 6 polymorphisms have a favourable effect on the development of HCC, while polymorphisms of GSTT1 and SULT1A1 might play role in increasing the susceptibility among smokers.
