Background Diabetes is positively associated with various cancers, but its relationship with tumors of the esophagus/esophagogastric junction remains unclear. Methods Data were harmonized across 13 studies in the International Barrett’s and Esophageal Adenocarcinoma Consortium, comprising 2309 esophageal adenocarcinoma (EA) cases, 1938 esophagogastric junction adenocarcinoma (EGJA) cases, 1728 Barrett's esophagus (BE) cases, and 16,354 controls. Logistic regression was used to estimate study‐specific odds ratios (ORs) and 95% CIs for self‐reported diabetes in association with EA, EGJA, and BE. Adjusted ORs were then combined using random‐effects meta‐analysis. Results Diabetes was associated with a 34% increased risk of EA (OR, 1.34; 95% CI, 1.00‐1.80; I 2 = 48.8% [where 0% indicates no heterogeneity, and larger values indicate increasing heterogeneity between studies]), 27% for EGJA (OR, 1.27; 95% CI, 1.05‐1.55; I 2 = 0.0%), and 30% for EA/EGJA combined (OR, 1.30; 95% CI, 1.06‐1.58; I 2 = 34.9%). Regurgitation symptoms modified the diabetes‐EA/EGJA association ( P for interaction = .04) with a 63% increased risk among participants with regurgitation (OR, 1.63; 95% CI, 1.19‐2.22), but not among those without regurgitation (OR, 1.03; 95% CI, 0.74‐1.43). No consistent association was found between diabetes and BE. Conclusions Diabetes was associated with increased EA and EGJA risk, which was confined to individuals with regurgitation symptoms. Lack of an association between diabetes and BE suggests that diabetes may influence progression of BE to cancer.
