Predictors of Malignancy and Recommended Follow-Up for Patients with Negative Endoscopic Ultrasound-Guided Fine-Needle Aspiration of Suspected Pancreatic Lesions
Abstract
BACKGROUND: Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) can characterize and diagnose pancreatic lesions as malignant, but cannot definitively rule out the presence of malignancy. Outcome data regarding the length of follow-up in patients with negative or nondiagnostic EUS-FNA of pancreatic lesions are not well-established.
