Serum levels of vitamin B6 and methionine were inversely associated with risk for lung cancer, according to the results of a large cohort study reported in the June 16issue of the Journal of the American Medical Association.
Between 1992 and 2000, 385,747 of the 519,978 EPIC participants donated blood samples for measurement of serum levels for 6 factors of 1-carbon metabolism and cotinine. There were 899 patients with lung cancer identified by 2006, to which 1770 control participants were matched by country, sex, birth date, and blood collection date.
Elevated serum levels of B6 and methionine were associated with a lower risk for lung cancer after accounting for smoking.
