Clinical Trial Summary

The aim of this study is to compare the diagnostic accuracy of two EUS-guided tissue acquisition devices; the 25G Echotip Ultra Fine Needle Aspiration (FNA) device and the 20G Echotip ProCore Fine Needle Biopsy (FNB) device.

Description:

Endoscopic ultrasound (EUS)-guided tissue acquisition has emerged as a valuable method to diagnose and stage malignancies. During Endoscopic Ultrasound (EUS), tissue samples can be obtained for pathological evaluation with different devices. Fine needle aspiration (FNA) provides a cytological specimen. Unfortunately, in a cytological specimen, inflammatory changes may be undistinguishable from well-differentiated dysplasia. Moreover, for neoplasms such as lymphomas and stromal tumors, tissue architecture and cell morphology are essential for accurate pathological assessment. Therefore, pathologists generally prefer a histological specimen. Fine needle biopsy (FNB) has the advantage of obtaining a histological specimen, which may lead to better diagnostic performance. However, FNB needles are stiffer and more difficult to handle, which can complicate tissue acquisition. In addition, the superiority of histology over cytology in EUS-guided tissue sampling has not been proven yet. For instance, tissue, obtained by FNA and processed with the new cell-block technique, may equal the diagnostic yield of histological tissue cores.

A recent meta-analysis suggested that 25G is the optimal FNA needle size to obtain an adequate cytological specimen. In this study, we aim to compare the properties and merits of a newly designed, more flexible, 20G EUS ProCore FNB device to a conventional 25G EUS-FNA device.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Diagnostic Accuracy	Diagnostic accuracy is the number of correctly diagnosed cases as compared to gold standard diagnosis; Gold standard diagnosis is defined as; in operated patients; based on the surgical resection specimen; in non-operated patients; based on the conclusions of the diagnostic work-up (combined outcomes of tissue sampling and imaging studies), and confirmed by a compatible clinical disease course of at least 9 months	27 months
Secondary	Number of Participants in Whom Target Lesion Was Sampled	records if a target lesion was reached during the procedure using the randomised needle or not	1 day
Secondary	Presence of Vital Target Cells Per Case, Per Needle Type	Presence of sufficient vital target cells, as in, target organ cells to provide a diagnosis (yes or no)	after 27 months
Secondary	Number of Patients With Adverse Events Per Needle Type	adverse events per needle type, up to 27 months after procedure	27 months after procedure
Secondary	Diagnostic Yield of the First Needle Pass	Yield is expressed as sample sufficiency for diagnostic analysis by pathologists, this was either sufficient or not	after 27 months
Secondary	On-site Pathological Evaluation Performed	Presence of pathologist on site during procedure	27 months
