Background: Dietary intake influences gut microbiome composition, which in turn may be associated with colorectal cancer (CRC). Associations of the gut microbiome with colorectal carcinogenesis may be mediated through bacterially regulated, metabolically active metabolites, including trimethylamine N‐oxide (TMAO) and its precursors, choline, L‐carnitine, and betaine. Methods: Prospective associations of circulating TMAO and its precursors with CRC risk were investigated. TMAO, choline, betaine, and L‐carnitine were measured in baseline serum samples from 761 incident CRC cases and 1:1 individually matched controls in the prospective Prostate, Lung, Colorectal, Ovarian Cancer Screening Trial Cohort using targeted fully quantitative liquid chromatography tandem mass spectrometry panels. Prospective associations of the metabolites with CRC risk, using multivariable conditional logistic regression, were measured. Associations of a priori–selected dietary exposures with the four metabolites were also investigated. Results: TMAO and its precursors were not associated with CRC risk overall, but TMAO and choline were positively associated with higher risk for distal CRC (continuous ORQ90 vs. Q10 [95% CI] = 1.90 [CI, 1.24–2.92; p =.003] and 1.26 [1.17–1.36; p <.0001], respectively). Conversely, choline was inversely associated with rectal cancer (ORQ90 vs. Q10 [95% CI] = 0.77 [0.76–0.79; p <.001]). Red meat, which was previously associated with CRC risk in the Prostate, Lung, Colorectal, Ovarian Cancer Screening Trial Cohort , was positively associated with TMAO (Spearman rho = 0.10; p =.0003). Conclusions: Serum TMAO and choline may be associated with higher risk of distal CRC, and red meat may be positively associated with serum TMAO. These findings provide insight into a potential microbially mediated mechanism underlying CRC etiology. In a prospective study among men and women in the United States, we measured circulating trimethylamine N‐oxide (TMAO), choline, betaine, and L‐carnitine and found that TMAO and choline were positively associated with distal colon cancers. Our findings support future studies into underlying mechanisms and potential TMAO‐targeted interventions to mitigate colorectal cancer risk. [ABSTRACT FROM AUTHOR] |
