Study 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.

Read the detailed 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.

    FNB first, then FNA

    In an endoscopic ultrasound-guided procedure, Shark Core Fine Needle Biopsy (FNB) will be performed first, followed by Fine Needle Aspiration (FNA).

Interventions

  • DeviceFine Needle Biopsy (FNB)

    The Shark Core FNB is an FDA approved device for sampling of submucosal lesions, mediastinal masses, lymph nodes and intraperitoneal masses. FNB will be performed by 22 gauge for pancreas head and by 19 gauge for all the other sites.

    Also known as: Shark Core Fine Needle Biopsy

  • DeviceFine Needle Aspiration (FNA)

    Fine needle aspiration is a type of biopsy procedure. In fine needle aspiration, a thin needle is inserted into an area of abnormal-appearing tissue or body fluid, and histological material is obtained. FNA will be performed with a standard 25g needle in the usual fashion using back and forth passes for 30 seconds.
