Meta-analysis of cohort studies links daily alcohol above 24 g to 10-30% higher pancreatic cancer risk after former-drinker bias correction
Corrected meta-analysis demonstrates a clear dose-response between alcohol intake and incident pancreatic cancer. Adjustment for former-drinker bias materially strengthens causal inference beyond prior observational summaries. Findings support adding pancreatic cancer to alcohol-related cancer lists used for policy and clinical guidance.
Next steps include replication in large consortia such as PanScan with repeated alcohol measures and Mendelian randomization to strengthen causality. Regulators should consider updating cancer warning labels and primary-care brief-intervention thresholds if additional cohorts confirm the 24 g threshold.
IARC Monographs: pancreatic cancer will be upgraded to sufficient evidence in the next alcohol re-evaluation scheduled within 36 months.
