Abstract

Background & Aims: Endoscopic ultrasound with fine-needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the gastrointestinal tract. Fine-needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. Methods: This is a multicenter, prospective randomized clinical trial from 6 large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion. Demographics, size, location, number of needle passes, and final diagnosis were recorded. Results: After enrollment, 135 patients were randomized to FNA (49.3%), and 139 patients were randomized to FNB (50.7%).The following lesions were sampled: mass (n = 210, 76.6%), lymph nodes (n = 46, 16.8%), and submucosal tumors (n = 18, 6.6%). Final diagnosis was malignancy (n = 192, 70.1%), reactive lymphadenopathy (n = 30, 11.0%), and spindle cell tumors (n = 24, 8.8%). FNA had a diagnostic yield of 91.1% compared with 88.5% for FNB (P = .48). There was no difference between FNA and FNB when stratified by the presence of on-site cytopathology or by type of lesion sampled. A median of 1 needle pass was needed to obtain a diagnostic sample for both needles. Conclusions: FNA and FNB obtained a similar diagnostic yield with a comparable number of needle passes. On the basis of these results, there is no significant difference in the performance of FNA compared with FNB in the cytologic diagnosis of solid lesions adjacent to the gastrointestinal tract.
