What the trial is, and whether it could suit you

Cancer associated fibroblasts (CAFs) can promote tumor cell proliferation, migration, invasion, and angiogenesis through immunosuppressive effects and the production of mediators, thereby promoting tumor growth and progression. The characteristic of CAFs is high expression of fibroblast activation protein (FAP). In approximately 90% of epithelial derived tumors, FAP is highly overexpressed on the membrane of CAFs. Contrary to CAFs, FAP expression is lower or absent in normal tissues. Therefore, FAP inhibitors (FAPI) targeting FAP can overcome the limitations of 18F-2-fluoro.2-deoxy-D-glucose fluorodeoxyglucose(18F-FDG) PET imaging. But like 18F-FDG, wound healing, fibrosis, and inflammation can also uptake FAPI.. Therefore, a comparison of the performance of 18F-FDG and 18F-FAPI PET imaging in diagnosing primary and metastatic lesions of various types of cancer is conducted to evaluate t
