ABSTRACT
BACKGROUND:
Long-term energy balance-related factors (i.e. lifestyle and physiological factors that influence the equilibrium between energy intake and energy expenditure over an extended period) like body mass index (BMI) are linked to colorectal cancer (CRC) risk, but their impact on CRC survival is unclear. We explored associations between these long-term energy balance-related factors and survival, and examined potential differences across metabolic Warburg-subtypes.METHODS:
Associations between long-term energy balance-related factors and survival in the total series of CRC patients (n=2,347) obtained from the prospective Netherlands Cohort Study, as well as according to Warburg-subtype (Warburg-low n=652, Warburg-moderate n=802, Warburg-high n=797), were investigated using Cox regression analysis.RESULTS:
Among the long-term energy balance-related factors studied, only increasing pre-diagnostic BMI was associated with a borderline significant poorer overall survival in CRC patients (HR5kg/m2 1.07; 95%CI 0.99-1.15). Stratified analyses showed that pre-diagnostic weight gain (HR5kg 1.06; 95%CI 1.00-1.12), and potentially increased height (HR5cm 1.04; 95%CI 0.98-1.11), were associated with poor overall survival only in patients with Warburg-high CRC. Increasing pre-diagnostic BMI was associated with poor survival only in patients with Warburg-moderate CRC (CRC-specific HR5kg/m2 1.12; 95%CI 0.96-1.32, overall HR5kg/m2 1.20; 95%CI 1.05-1.36). No consistent patterns were observed across energy-restriction proxies.CONCLUSIONS:
Maintaining a healthy pre-diagnostic BMI may be beneficial for CRC survival. Moreover, associations between pre-diagnostic BMI, weight change, early-life energy restriction, height and CRC survival differed according to Warburg-subtype. IMPACT Understanding the biological pathways involved in associations between energy balance-related factors and CRC survival could help refine prevention strategies in the future.
