Endoscopic Ultrasound Guided Fine Needle Biopsy (EUS-FNB-SC) Using a Novel Fork Needle

2016-02-09 19:38:22 | BioPortfolio

Summary

This is a clinical trial to compare two needles used in biopsy techniques to acquire tissue from pancreatic cancer. The hypothesis is that the tissue yield, as measured by tumor DNA and cellular material is superior for Flexible Needle Biopsy (FNB) compared with conventional Fine Needle Aspiration (FNA). Specifically, FNB will increase the proportion of cases in which sufficient DNA is obtained to allow genomic profiling and whole exome sequencing.

Description

This is a single-blinded randomized controlled trial with paired evaluation of conventional FNA needle versus FNB needle stratified by lesion location (pancreas head tumor versus pancreas body/tail). A minimum of 4 passes ( 2 with each needle) will be performed from all the lesions. After each pass of needle, the on-site cytopathologists will evaluate the adequacy and the degree of the pathological changes in the obtained material. Based on the information provided by the onsite cytopathologists, the endosonographer will repeat the FNA until enough histological material is obtained to confirm a diagnosis. Patients will be assessed immediately after procedure and during the first 30 days with a follow-up.

Medical and Biotech [MESH] Definitions

Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.

Using fine needles (finer than 22-gauge) to remove tissue or fluid specimens from the living body for examination in the pathology laboratory and for disease diagnosis.

Removal and examination of tissue obtained through a transdermal needle inserted into the specific region, organ, or tissue being analyzed.

Usage of a single needle among two or more people for injecting drugs. Needle sharing is a high-risk behavior for contracting infectious disease.

The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
