Randomized Prospective Trial of EUS-FNA Versus EUS-FNB Using a Novel Core Biopsy Needle
Endoscopic ultrasound (EUS) is paramount in the diagnosis and evaluation of cancers involving
the gastrointestinal tract. EUS allows for the acquisition of cellular (fine needle aspirate
- FNA) or tissue biopsy (fine needle biopsy - FNB) for diagnostic purposes. This has
traditionally been done with fine needle aspirate where a needle is inserted into the tumor
and potentially malignant cells are extracted for microscopic analysis. More recently, a
needle that allows a tissue biopsy for histologic analysis has been FDA approved.
The Echotip Procore (Cook Medical) core biopsy needle (ETP), has been demonstrated to provide
excellent efficacy for core biopsy samples. Final diagnostic yield using this needle ranges
from 80-90% and appears to be significantly greater than EUS-FNA for lesions requiring
histology for diagnosis. However, there is currently only limited data from prospective
studies comparing EUS-FNA to EUS-FNB with the ETP needle. The investigators propose a
randomized, prospective, cross-over study comparing diagnostic accuracy of EUS-FNA to
EUS-FNB.

We will compare tissue samples obtained by standard FNA to FNB with a sample size of 140
patients with the primary outcome being diagnostic yield. Each patient will be randomized to
FNA or FNA. If after 3 passes the on-site evaluation remains inadequate, the endoscopist will
crossover to the other arm.
