Abstract

Background/objectives: Acute pancreatitis (AP) may obscure small pancreatic cancers (PCs) on computed tomography during the acute phase. Surveillance with magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography (EUS) may enhance early detection and improve patient outcomes. This study evaluated the impact of early MRCP/EUS surveillance on PC outcomes in AP patients and identified high-risk subgroups for early screening.

Methods: We retrospectively analyzed 1562 AP patients treated between 2010 and 2021, categorizing them into early surveillance (MRCP/EUS within three months of AP onset; n = 760) and nonearly surveillance groups (n = 802). Key outcomes included time to PC diagnosis, surgical resection rate, tumor stage, and overall survival. Multivariate analysis was performed to identify risk factors for concealed PC in AP patients.

Results: Among 27 PC cases analyzed, the early surveillance group achieved significantly earlier diagnosis, higher surgical resection rates, increased detection of early-stage PC, and improved overall survival compared with the nonearly surveillance group. Multivariate analysis revealed that subthreshold main pancreatic duct (MPD) dilation (≥2.5 mm) and moderately severe AP were significant predictors of PC.

Conclusions: Early MRCP/EUS surveillance in AP patients facilitates timely detection of occult PC and enhances patient prognosis. These findings support prioritizing early surveillance for AP patients with subthreshold MPD dilation and moderately severe disease. Further large-scale studies are warranted to validate these strategies in clinical practice.

期刊介绍： Pancreatology is the official journal of the International Association of Pancreatology (IAP), the European Pancreatic Club (EPC) and several national societies and study groups around the world. Dedicated to the understanding and treatment of exocrine as well as endocrine pancreatic disease, this multidisciplinary periodical publishes original basic, translational and clinical pancreatic research from a range of fields including gastroenterology, oncology, surgery, pharmacology, cellular and molecular biology as well as endocrinology, immunology and epidemiology. Readers can expect to gain new insights into pancreatic physiology and into the pathogenesis, diagnosis, therapeutic approaches and prognosis of pancreatic diseases. The journal features original articles, case reports, consensus guidelines and topical, cutting edge reviews, thus representing a source of valuable, novel information for clinical and basic researchers alike.
