The human oral microbiome and risk of colorectal cancer within three prospective cohort studies in the United States.

ABSTRACT:

Background

Oral microbes detected in feces have been associated with colorectal cancer (CRC) in cross-sectional studies. This study investigated the prospective associations between the oral microbiome and incident CRC in the Agricultural Health Study (AHS), National Institutes of Health-AARP (NIH-AARP) Diet and Health Study, and Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.

Methods

Individuals with oral samples collected before incident CRC diagnoses were identified in the AHS (N = 331), NIH-AARP (N = 249), and PLCO (N = 446) and compared with referent subcohorts (N = 3431). The V4 region of the 16S ribosomal RNA gene was sequenced from oral wash DNA, and the data were processed with QIIME2. Hazard ratios (HRs) and 95% confidence intervals (CIs) for
