Pancreas Adenocarcinoma clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

EUS-guided Fine Needle Biopsy With a New Core Histology Needle Versus Conventional Fine Needle Aspiration

Start date: September 2011
Phase: N/A
Study type: Interventional

Endoscopic ultrasound (EUS) is a well-established tool for the diagnosis and staging of many gastrointestinal conditions, including but not limited to, malignant and pre-malignant neoplasms of the pancreas, esophagus, rectum, and submucosal tumors developing along the gastrointestinal tract. EUS is the most sensitive test for the detection of focal lesions within the pancreas and is the most accurate method for diagnosing pancreas cancer. A biopsy method for tissue sampling via EUS called fine needle aspiration (FNA) was developed that enables a small needle to be passed into the lesion of interest under ultrasound guidance, obtaining cellular material for cytology. EUS-FNA is currently recommended for the diagnosis of cystic and solid mass lesions within and adjacent to the gastrointestinal tract. Yet in certain clinical circumstances, it is more desirable and sometimes necessary to obtain a core tissue biopsy for histology rather than the cellular material for cytology obtained with EUS-FNA. Furthermore, histology may generally increase the diagnostic yield of EUS-FNA compared to cytology. It is with these aims in mind that a new type of needle, the fine needle biopsy (EUS-FNB) device was developed to enable core tissue sampling. Since a comparison of these to methods has yet to be made, the aim of this study is to perform a direct comparison of the sampling adequacy and diagnostic yield of the new EUS-FNB needle with the conventional EUS-FNA needle.
