摘要: Low consumption of vegetables and fruits, which leads to insufficient folate intake, is associated with increased risk several types cancer, including head neck squamous cell carcinoma (HNSCC). Functional polymorphisms in genes encoding one-carbon metabolism enzymes, such as methylenetetrahydrofolate reductase (MTHFR C677T A1298C), methionine synthase (MTR A2756G), (MTRR A66G) thymidylate (TS), influence thus might impact on HNSCC risk. We conducted a case-control study 237 cases newly histologically diagnosed 711 age- sex-matched non-cancer controls clarify associations these five polymorphisms. Gene-environment interactions between smoking drinking habit were also evaluated by logistic regression analysis. Dietary intake was inversely None the showed any significant genotype alone, but we found MTHFR C667T (P = 0.04), MTR A2756G 0.04) MTRR A66G 0.03) The results suggest that there may be metabolism-related alcohol for
