Phase 2

Conditions
Lymphoma
Solid Tumors
Mesenchymal Tumor
Autoimmune Pancreatitis
Registration Number
NCT02766842
Lead Sponsor
Johns Hopkins University
Brief Summary

Diagnosis of lesions of pancreas, the upper gastrointestinal tract, as well as adjacent structures, such as lymph nodes, is still showing advancements especially with the increased use of endoscopic ultrasound. Endoscopic ultrasound-guided fine needle aspiration and fine needle biopsy (EUS-FNA/FNB) have become mainstay diagnostic techniques for these lesions. The purpose of the study is to compare between the currently used, ProCore needles and the new biopsy needle, SharkCore, for the histological diagnosis and evaluation of lesions.

Detailed Description

Endoscopic ultrasound-guided fine needle aspiration and fine needle biopsy (EUS-FNA/FNB) have become mainstay diagnostic techniques for the diagnosis and evaluation of lesions of the pancreas, the upper gastrointestinal tract, as well as adjacent structures, including lymph nodes. Cytology specimens provided from FNA cannot fully characterize certain neoplasms such as lymphomas or mesenchymal tumors. Core biopsy specimens for histological examinations are needed to provide accurate diagnoses.

ProCore needles (ProCore, Wilson-Cook Medical Inc. Winston-Salem, NC) were designed to obtain histological and cytological samples. Studies comparing ProCore needles with standard FNA needles showed no significant difference in diagnostic accuracy, histological core tissue procurement or mean number of passes.

To overcome the above mentioned limitations (mainly suboptimal core tissue procurement rates), a new novel SharkCore needle (Beacon Endoscopic, Newton, MA, USA) has been designed and approved for clinical human use by the FDA.

The objective of the study is to compare the new EUS guided histology biopsy needle SharkCore to the currently used EUS histology needle, ProCore, for the histological diagnosis and evaluation of lesions.

Study & Design

Study Type
INTERVENTIONAL
Study Design
PARALLEL
Primary Outcome Measures
NameTimeMethod
Diagnostic accuracy of needle as assessed by diagnostic yield of needle and final diagnosis methodUp to 1 month

The final diagnosis of tissue from needle will be compared to the final diagnosis reached either by surgical removal of mass or other method of biopsy

Secondary Outcome Measures
NameTimeMethod
Number of passes to procure core tissue from needleDuring procedure

The number of passes needed to acquire core tissue as assessed by the pathologist in the room.

Safety of tissue procurement by needleUp to 1 year

All complications related to needle used will be recorded with a preset questionnaire to measure the frequency of complications related to needle used.

Procedure timeDuring procedure

Time required to acquire tissue using each needle will be recorded from time of needle insertion to time of core tissue procurement as per pathologist.
