Abstract Background Certain dietary patterns can elicit systemic and intestinal inflammatory responses, which may influence adaptive anti‐tumor immune responses and tumor behavior. We hypothesized that pro‐inflammatory diets might be associated with higher colorectal cancer mortality and that the association might be stronger for tumors with lower immune responses. Methods We calculated an empirical dietary inflammatory pattern (EDIP) score in 2829 patients among 3988 incident rectal and colon carcinoma cases in the Nurses’ Health Study and Health Professionals Follow‐up Study. Using Cox proportional hazards regression analyses, we examined the prognostic association of EDIP scores and whether it might be modified by histopathologic immune reaction (in 1192 patients with available data). Results Higher EDIP scores after colorectal cancer diagnosis were associated with worse survival, with multivariable‐adjusted hazard ratios (HRs) for the highest versus lowest tertile of 1.41 (95% confidence interval [CI]: 1.13–1.77; Ptrend = 0.003) for 5‐year colorectal cancer‐specific mortality and 1.44 (95% CI, 1.19‐1.74; Ptrend = 0.0004) for 5‐year all‐cause mortality. The association of post‐diagnosis EDIP scores with 5‐year colorectal cancer‐specific mortality differed by degrees of tumor‐infiltrating lymphocytes (TIL; Pinteraction = .002) but not by three other lymphocytic reaction patterns. The multivariable‐adjusted, 5‐year colorectal cancer‐specific mortality HRs for the highest versus lowest EDIP tertile were 1.59 (95% CI: 1.01–2.53) in TIL‐absent/low cases and 0.48 (95% CI: 0.16–1.48) in TIL‐intermediate/high cases. Conclusions Pro‐inflammatory diets after colorectal cancer diagnosis were associated with increased mortality, particularly in patients with absent or low TIL. |
