The U.S. FDA approved Netspot, the first kit for the preparation of gallium Ga 68 dotatate injection, a radioactive diagnostic agent for positron emission tomography (PET) imaging. This radioactive probe will help locate tumors in adult and pediatric patients with the rare condition, somatostatin receptor positive neuroendocrine tumors (NETs).
NETs are rare noncancerous (benign) or cancerous (malignant) tumors that develop in the hormone-producing cells of the body’s neuroendocrine system. These cells are found throughout the body in organs, such as the stomach, intestines, pancreas, lungs and other locations. NETs have receptors for somatostatin, a hormone that regulates the endocrine system. Ga 68 dotatate, a positron emitting analogue of somatostatin, works by binding to such receptors.
Use of advanced imaging techniques to detect rare neuroendocrine tumors at an early stage in patients is critical. Netspot provides another diagnostic tool whose results will help clinicians determine the location and extent of the tumor. This information is important for planning the appropriate course of therapy. It is marketed by Advanced Accelerator Applications USA, Inc.
