Endoscopic Ultrasound Fine-Needle Aspiration Characteristics of Primary Adenocarcinoma versus Other Malignant Neoplasms of The Pancreas

Abstract

Adenocarcinoma was more likely to be present in the head of the pancreas, have lymph node and vascular involvement, as well as evidence of pancreatic duct and common bile duct obstruction. Of all malignant pancreatic lesions analyzed by EUS-FNA, 25% were NPPA, suggesting that FNA is crucial in establishing a diagnosis and may be helpful in preoperative planning.
