Abstract
Background We investigated whether prediagnostic reported intake of dairy products and dietary calcium are associated with colorectal cancer (CRC) survival. Methods Data from 3,859 subjects with CRC (42.1% male, mean age at diagnosis 64.2 ± 8.1 years) in the European Investigation into Cancer and Nutrition (EPIC) cohort were analyzed. Intake of dairy products and dietary calcium was assessed at baseline (1992-2000) using validated, country-specific dietary questionnaires. Multivariable Cox regression models were used to calculate hazard ratios (HR) and corresponding 95% confidence intervals (95%-CI) for CRC specific death (n=1,028) and all-cause death (n=1,525) for different quartiles of intake. Results The consumption of total dairy... (More)

Intake of dairy products and dietary calcium was assessed at baseline (1992-2000) using validated, country-specific dietary questionnaires. Multivariable Cox regression models were used to calculate hazard ratios (HR) and corresponding 95% confidence intervals (95%-CI) for CRC specific death (n=1,028) and all-cause death (n=1,525) for different quartiles of intake. Results The consumption of total dairy products was not statistically significantly associated with risk of CRC-specific death (adjusted HR Q4 vs. Q1: 1.17 95%-CI 0.97-1.43) nor of all-cause death (Q4 vs. Q1: 1.16 95%-CI 0.98-1.36). Multivariable adjusted HRs for CRC-specific death (Q4 vs. Q1) were 1.21 (95%-CI 0.99-1.48) for milk, 1.09 (95%-CI 0.88-1.34) for yoghurt and 0.93 (95%-CI 0.76-1.14) for cheese. The intake of dietary calcium was not associated with the risk of CRC-specific (adjusted HR Q4 vs. Q1: 1.01 95%-CI 0.81-1.26) nor of all-cause death (Q4 vs. Q1: 1.01 95%-CI 0.84-1.21). Conclusions The prediagnostic reported intake of dairy products and dietary calcium are not associated with disease-specific or all-cause risk of death in patients diagnosed with CRC. Impact The impact of diet on cancer survival is largely unknown. This study shows that despite it's inverse association with CRC risk, the prediagnostic intake of dairy and dietary calcium do not affect CRC survival. (Less)
