Abstract
Background
Accurate diagnosis of pancreatic lesions remains challenging. This study evaluated the diagnostic value of targeted DNA-based next-generation sequencing (NGS) of tissue obtained by endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) and its contribution to pancreaticobiliary multidisciplinary tumor board (MDTB) discussions.
Methods
A retrospective analysis was conducted using a prospectively maintained database at Ghent University Hospital (March 2021–September 2024). Only patients undergoing targeted DNA NGS on EUS-FNA/FNB samples were included and reviewed during MDTB meetings. Diagnostic performance and influence on management were compared with final diagnoses established by clinical follow-up and/or surgical pathology.
Results
The final cohort comprised 120 focal pancreatic lesions. Ninety-one percent of solid masses (50/55) were malignancies. Cytopathology alone identified pancreatic cancer (PC) or high-grade dysplasia (HGD) in 27 cases (sensitivity 54%), whereas NGS alone identified 42 (sensitivity 84%). Combined cytopathology and NGS detected 45/50 malignancies (90%). Only two samples were non-diagnostic, yielding an overall diagnostic success of 96% (53/55).
NGS was technically successful in 33/65 (51%) cystic lesions. Surgery was undertaken in 20 patients, with HGD or carcinoma confirmed in 11 (55%). Molecular profiling combined with cytopathology guided surgical decision-making in 6/11 patients (54%) compared with 3/11 (27%) with cytopathology alone.
Conclusion
Targeted NGS improves diagnostic accuracy in solid pancreatic lesions and supports surgical decision-making for cystic lesions. Integration of molecular findings into MDTB discussions enhances precision and timeliness of pancreatic cancer treatment.
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.
