Spots Global Cancer Trial Database for A Randomized Prospective Comparison of the New EUS Guided Acquire TM Needle Biopsy vs EUS Guided Fine Needle Aspiration for Suspected Solid Gastrointestinal Lesions

Study Description

Brief Summary: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is the technique of choice to evaluate solid gastrointestinal (GI) lesions. The tissue acquired using this technique is essential for diagnosis of diseases like sub-mucosal masses (GIST), lymphoma, autoimmune pancreatitis and pancreatic cancer. Also the availability of adequate tissue will enable performance of molecular profiling and personalized oncologic therapy. The current needle used for tissue acquisition rarely provides tissue blocks needed for histology assessment. Hence, a better needle device with a good safety profile is needed to solve this technical difficulty. The new AcquireTM fine needle biopsy device could over come this difficulty because of its unique designs. The additional cutting edge surface allows better tissue access and provides core tissue (\>90%) for histology. The safety profile of this new device is comparable to the conventional FNA needle thereby making it an ideal device for tissue acquisition.

Detailed Description: Endoscopic ultrasound has become the preferred method to characterise gastrointestinal (GI) wall and peri-gastrointestinal masses. A major strength is that it can be used to guide fine needle aspiration (EUS-FNA) of any lesion in the wall or within 5cm from the GI tract. However, EUS-FNA has a major drawback- it rarely able to provide tissue blocks. Thus multiple passes, each of them time consuming, are necessary to obtain adequate cellular samples for cytological analysis. A radically new design of FNA needle (AcquireTM) has recently become available. The needle has an additional cutting edge surface, which allows better tissue access and acquires intact large core samples. The flexibility of the needle permits its use in tortuous anatomy, thereby making it an ideal needle for FNA. The new AcquireTM fine needle biopsy device (FNB) provides core tissue (\>90%) for histology. This ability of the needle will enable us to obtain core tissue in fewer passes and make a precise diagnosis. However, at present there is no prospective randomized study to validate this finding. The investigators hypothesize that the unique cutting system of Acquire TM fine needle biopsy (FNB) device will improve the specimen adequacy of solid intestinal and extra-intestinal lesions by providing a good core tissue for analysis.
