Understanding metachronous cancer associations can modify pancreas cancer risk. The objective of this study was to investigate the association of nonpancreatic cancers with subsequent pancreatic adenocarcinoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p>The authors used data from the US Surveillance, Epidemiology, and End Results (SEER) registries to identify 1,618,834 individuals who had a primary malignancy and subsequent pancreatic adenocarcinoma (n = 4013).

Among patients who had a first malignancy at ages 50 to 64 years, the risk was increased after cancers of the stomach (RR, 1.88; 95% CI, 1.13\u20102.93), hepatic flexure (RR, 2.25; 95% CI, 1.08\u20104.13), lung and bronchus (RR, 1.46; 95% CI, 1.16\u20101.82), pharynx (RR, 2.26; 95% CI, 1.13\u20104.04), and bladder (RR, 1.24; 95% CI, 1.03\u20101.48).
