BACKGROUND/OBJECTIVES: B vitamins and related enzymes involved in one-carbon metabolism are necessary for DNA replication, DNA repair and regulation of gene expression. Disruption of one-carbon mechanism may affect cancer risk. We investigated prospectively the relationship between dietary intakes of methionine, B vitamins associated with one-carbon metabolism and risk of lung cancer. SUBJECTS/METHODS: The Melbourne Collaborative Cohort Study recruited 41,514 men and women aged 40-69 years between 1990 and 1994. During follow-up of 14,595 men and 22,451 women for an average of 15 years, we ascertained 348 incident lung cancers. Dietary intake of B vitamins and methionine was estimated from a..View full abstract
