Evaluation of endoscopic ultrasound fine-needle aspiration versus fine-needle biopsy and impact of rapid on-site evaluation for pancreatic masses.


ABSTRACT: Background and study aims ?Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is traditionally considered a first-line strategy for diagnosing pancreatic lesions; however, given less than ideal accuracy rates, fine-needle biopsy (FNB) has been recently developed to yield histological tissue. The aim of this study was to compare diagnostic yield and safety between EUS-FNA and EUS-FNB in sampling of pancreatic masses. Patients and methods ?This was a multicenter retrospective study to evaluate efficacy and safety of EUS-FNA and EUS-FNB for pancreatic lesions. Baseline characteristics including sensitivity, specificity, and accuracy, were evaluated. Rapid on-site evaluation (ROSE) diagnostic adequacy, cell-block accuracy, and adverse events were analyzed. Subgroup analyses comparing FNA versus FNB route of tissue acquisition and comparison between methods with or without ROSE were performed. Multivariable logistic regression was also performed. Results ?A total of 574 patients (n?=?194 FNA, n?=?380 FNB) were included. Overall sensitivity, specificity, and accuracy of FNB versus FNA were similar [(89.09?% versus 85.62?%; P ?=?0.229), (98.04?% versus 96.88?%; P ?=?0.387), and 90.29?% versus 87.50?%; P ?=?0.307)]. Number of passes for ROSE adequacy and cell-block accuracy were comparable for FNA versus FNB [(3.06?±?1.62 versus 3.04?±?1.88; P ?=?0.11) and (3.08?±?1.63 versus 3.35?±?2.02; P ?=?0.137)]. FNA?+?ROSE was superior to FNA alone regarding sensitivity and accuracy [91.96?% versus 70.83?%; P ?
