A recent study reported in the May issue of the Journal of Nuclear Medicine demonstrates that Ga-68 DOTATATE PET/CT scans are superior to In-111 pentetreotide scans, the current imaging standard in the United States for detecting neuroendocrine tumors (NETS), and could significantly impact treatment management.
NETS occur mostly in the respiratory and digestive tracts and are usually slow-growing. They can be difficult to diagnose, and many treatment options exist. It's therefore critical to delineate the extent of disease accurately for proper management. While the incidence of NETS is relatively low, with 2.5-5 cases per 100,000 in the United States, data from the National Cancer Institute show a five-fold increase worldwide from 1973 to 2004. NETS can be malignant and, although they comprise less than two percent of gastrointestinal cancers, they are more prevalent than stomach and pancreatic cancers combined.
