Abstract: Chronic alcohol drinking is a strong risk factor for esophageal squamous cell carcinoma (ESCC). In this study, the correlation between the HO-1 gene promoter polymorphism and alcohol, along with the risk of ESCC on Chinese males, was analyzed.The case-control study was performed in 143 ESCC patients and 264 cancer-free controls. All subjects were males. Allelotypic frequencies of (GT)n repeat were examed by PCR-based genotyping and DNA sequencing. The frequencies of L-allele and L-allele carriers (S/L and L/L genotypes) was significantly higher in ESCC patients than in controls (p = 0.001 and 0.004), The adjusted ORs for ESCC with S/L and L/L genotypes vs S/S genotype was 2.212 (95% CI 1.297-3.775, p = 0.004). The adjusted ORs for light, moderate and heavy drinking was 1.467, 5.215 and 9.525 respectively among L-allele carriers (S/L and L/L genotypes ) and 1.389, 2.096 and 3.039 respectively for the S/S genotype. Length of a (GT)n repeat in the HO-1 gene promoter may be associated with the development of ESCC in Chinese male drinkers. Reducing alcohol intake might be most protective among L-allele carriers of this polymorphism.
