abstract = {Associations of energy balance components, including
physical activity and obesity, with colorectal cancer risk
and mortality are well established. However, the gut
microbiome has not been investigated as underlying
mechanism. We investigated associations of physical
activity, BMI, and combinations of physical activity/BMI
with gut microbiome diversity and differential abundances
among colorectal cancer patients. N=179 patients with
colorectal cancer (stages I-IV) were included in the study.
Pre-surgery stool samples were used to perform 16S rRNA gene
sequencing (Illumina). Physical activity (MET hrs/wk) during
the year before diagnosis was assessed by questionnaire and
participants were classified as being active vs. inactive
based on guidelines. BMI at baseline was abstracted from
medical records. Patients were classified into four
combinations of physical activity levels/BMI. Lower gut
microbial diversity was observed among 'inactive' vs.
'active' patients (Shannon: P=0.01, Simpson: P=0.03),
'obese' vs. 'normal weight' patients (Shannon, Simpson, and
Observed species: P=0.02, respectively), and
'overweight/obese/inactive' vs. 'normal weight/active'
patients (Shannon: P=0.02, Observed species: P=0.04).
Results differed by sex and tumor site. Two phyla and 12
genera (Actinobacteria and Fusobacteria, Adlercreutzia,
Anaerococcus, Clostridium, Eubacterium, Mogibacteriaceae,
Olsenella, Peptinophilus, Pyramidobacter, RFN20,
Ruminococcus, Succinivibrio, Succiniclasticum) were
differentially abundant across physical activity and BMI
groups. This is the first evidence for associations of
physical activity with gut microbiome diversity and
abundances, directly among colorectal cancer patients. Our
results indicate that physical activity may offset gut
microbiome dysbiosis due to obesity. Alterations in gut
microbiota may contribute mechanistically to the energy
balance-colorectal cancer link and impact clinical
outcomes.},
