The CC genotype of ADH1B rs1229984 was significantly associated with cancer of larynx, pharynx, and nasal cavities (OR = 1.56, p = 0.001, Table 3), cancer of the pancreas (OR = 1.66, p = 0.018, Table 4), and cancer of the esophagus (OR = 4.10, p < 0.001, Table 5). Here, ADH1B is linked to esophageal cancer.
