Abstract:Objective: To investigate the relationship between ADH1B rs1229984 and ALDH2 rs671 polymorphisms and the susceptibility to lymphatic metastasis in esophageal cancer in a Chinese Han population. Methods: Genotypes were determined by matrixassisted laser desorption/ionizationtime of flight mass spectrometry(MALDITOF MS) method in 85 esophageal cancer lymphatic metastasis positive patients and 270 lymphatic metastasis negative patients. The associations between ALDH2 rs671 G>A and ADH1B rs1229984 A>G genotypes and the risk of esophageal cancer lymphatic metastasis were estimated by computing the odds ratio(OR) and their 95% confidence interval(CI). Results: The ALDH2 rs671 G>A genotype frequencies were 58.8%(GG), 38.8%(GA), 2.4%(AA) in the lymphatic positive group and 59.3%(GG), 37.4%(GA), 3.3%(AA) in the lymphatic negative group, respectively(χ2 =0.237, P=0.888); logistic regression analyses revealed that ALDH2 rs671 AA genotype could reduce the risk of lymphatic metastasis(adjusted OR=0.70, 95% CI=0.14-3.45) compared with ALDH2 rs671 GG genotype, but the difference was not statistically significant. The ADH1B rs1229984 A>G genotype frequencies were 38.8%(AA), 50.6%(AG), 10.6%(GG) in the lymphatic positive group and 42.8%(AA), 41.6%(AG), 15.6%(GG) in the lymphatic negative group, respectively(χ2 =2.553, P=0.279); logistic regression analyses revealed that ADH1B rs1229984 GG genotype could reduce the risk of lymphatic metastasis(adjusted OR=0.66, 95% CI=0.29-1.53) compared with ADH1B rs1229984 AA genotype, but the difference was not statistically significant. Conclusion: ALDH2 rs671 G>A and ADH1B rs1229984 A>G polymorphisms might not be associated with the risk of esophageal cancer lymph node metastasis, and awaits further investigation.
