abstract = {Physical activity and obesity are well-established factors
of colorectal cancer (CRC) risk and prognosis. Here, we
investigate associations of individual and combined physical
activity and BMI groups with pro-inflammatory biomarkers in
CRC patients.Self-reported physical activity levels were
classified as 'active' (≥8.75 MET-hrs/wk) vs. 'inactive'
(<8.75 MET-hrs/wk) in n=579 stage I-IV CRC patients enrolled
in the ColoCare Study. BMI [normal weight
(≥18.5-<25kg/m2), overweight (≥25-<30kg/m2), and obese
(≥30kg/m2)] was abstracted from medical records. Patients
were classified into four combinations of physical activity
levels and BMI. Biomarkers (CRP, SAA, IL-6, IL-8, and
TNF-α) in pre-surgery serum samples were measured using
Meso-Scale-Discovery platform. Regression models were used
to compute relative percent differences in biomarker levels
by physical activity and BMI groups.'Inactive' patients had
non-statistically significant higher IL-6 levels compared to
'active' patients $(+36\%,$ p=0.10). 'Obese' patients had
$88\%$ and $17\%$ higher CRP and TNF-α levels compared to
'normal weight' patients (p=0.03 and 0.02, respectively).
Highest CRP levels were observed among 'overweight or
obese/inactive' compared to 'normal weight/active' patients
(p=0.03).We provide evidence of associations between
individual and combined physical activity and BMI groups
with pro-inflammatory biomarkers. While BMI was identified
as the key driver of inflammation, biomarker levels were
higher among 'inactive' patients across BMI groups.This is
the largest study in CRC patients investigating associations
of energy balance components with inflammatory biomarkers.
Our results suggest that physical activity may reduce
obesity-induced inflammation in CRC patients and support the
design of randomized controlled trials testing this
hypothesis.},
