Objective: This study aimed to evaluate associations between endoscopic ultrasound (EUS) criteria for chronic pancreatitis (CP) and coexisting pancreatic intraepithelial neoplasia (PanIN) lesions. Methods: Patients with known or suspected CP who underwent pancreatic resection within a year of EUS were selected. Histology slides and EUS images were reviewed for evidence of pancreatic fibrosis. Results: Ninety-seven (51 men; mean age, 53 [12] years) underwent EUS within a 1 year or less of EUS. Pancreatic intraepithelial neoplasia lesions were found in 84 (87%) patients. Pancreatic intraepithelial neoplasia 1, 2, and 3 lesions were seen in 71 (83%), 10 (14%), and 1 (2%), respectively. Two patients had more than 1 PanIN grade (one had PanIN 1 and 2 and the other had PanIN 1 and 3). The mean number of EUS criteria for PanIN 1, 2, and 3 lesions were 3.9, 4.5, and 5.5, respectively. The odds ratio for the association between PanIN 2 and hyperechoic foci without shadowing in the pancreas head was 8.5 (P = 0.05). The odds ratio for the association between PanIN 2 and lobularity with honeycombing was 2.7 (P = ns). Advanced PanIN lesions had greater than or equal to 4 EUS criteria for CP. Conclusions: Pancreatic intraepithelial neoplasia lesions were highly prevalent in CP resections. Increasing PanIN grade is observed with increasing fibrosis score and increasing number of EUS criteria for CP.
