Purpose: To study the causes of esophageal cancer in Chaoshan and Taihang areas. Methods: By using gel-based DNA microarray genotyping method, four cancer-related polymorphisms including CYP1A1 m2, CYP1A1 m4, CYP2E1 Pst I and CYP2E1 Rsa I were studied with 565 (CYP1A1) or 482 (CYP2E1) cases and 468 (CYP1A1) or 466 (CYP2E1) controls. Results: For CYP1A1 m2, the mutant allele frequencies were 21.3% (Chaoshan) and 19.6% (Taihang), and OR for AG versus AA genotype (Chaoshan) was 1.855 (95% CI [1.227–2.805]). For CYP1A1 m4, no mutant allele was detectable. For CYP2E1 Pst I, the mutant allele frequencies were 27.3% (Chaoshan) and 29.4% (Taihang), and OR for GG versus CC genotype (Taihang) was 3.263 (95% CI [1.059–10.052]). For CYP2E1 Rsa I, the mutant allele frequencies were 27.3% (Chaoshan) and 29.6% (Taihang), and OR for CC versus TT genotype (Taihang) was 3.167 (95% CI [1.026–9.776]). Conclusion: The results suggest that AG genotype of CYP1A1 in Chaoshan area and GG (CC) genotype of CYP2E1 in Taihang area are significantly associated with esophageal cancer susceptibility.
