Dietary patterns associated with treatment outcomes in Stage III–IV pancreatic adenocarcinoma patients

This retrospective observational study analyzed data from 210 patients with Stage III–IV pancreatic adenocarcinoma drawn from real-world clinical settings via electronic medical records. The investigation focused on the association between specific dietary patterns—categorized as High-Fat Western, Mixed/Transitional, and Plant-Rich—and treatment outcomes, including chemotherapy response, progression-free survival, and overall survival. Multivariate logistic regression and Cox proportional hazards models were employed to examine independent associations between these exposures and the primary outcomes.

Significant differences in nutrient profiles were observed across the identified dietary groups. Specific effect sizes, absolute numbers, or precise p-values were not reported in the available data. The study also assessed secondary outcomes, noting that adverse events were observed, though details regarding serious adverse events, discontinuations, and overall tolerability were not reported. The specific direction of the associations regarding survival or response metrics was not detailed in the provided results.

Key limitations include the inherent constraints of evidence derived from real-world clinical settings, which may introduce confounding variables. The study phase and publication type were not reported, and funding or conflict of interest information was unavailable. Given the observational nature of the research, causality cannot be inferred. These findings should be interpreted as associations only, and clinical decisions regarding dietary interventions should not be based solely on this evidence.
