To improve diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in solid pancreatic lesions, on-site cytology review has been recommended. Because this is not widely available throughout the world, the aim of this study was to compare the diagnostic yield of EUS-FNA performed with rapid on-site evaluation (ROSE) versus 7 FNA passes without ROSE in pancreatic masses. In this multicenter randomized noninferiority trial, patients were randomized to ROSE versus 7 passes into a solid pancreatic mass. On the basis of the absolute difference in diagnostic yield with 7 passes versus cytopathologist-guidance, the noninferiority margin for the difference in diagnostic yield was defined as -15%. Definite diagnosis was defined to include positive for malignancy, neoplastic cells present, and negative for malignancy. A total of 142 patients were randomized with 73 in the cytopathologist arm and 69 in the 7 passes arm. Diagnostic yield for definite diagnosis was 78.3% with 7 passes and 78.1% with cytopathology guidance. With an absolute difference 0.2%, 95% CI -14.4 to 14.6, performing 7 passes was noninferior to cytopathologist-guided EUS-FNA. There was no significant difference in complications or time to perform FNA. A median of 5 passes were performed with ROSE. The median charge with onsite cytopathology was significantly greater than performing 7 passes $1058 (958, 1445) versus $375 (275, 460), p<0.001. The diagnostic yield for performing 7 passes during EUS-FNA into solid pancreatic masses is noninferior with lower charge compared to cytopathologist-guidance. This article is protected by copyright.
