As a novel radiotracer targeting fibroblast activation protein (FAP), 68Ga-JH04 is promising as an excellent imaging agent for various cancers. In this study, we observed the diagnostic performance of 68Ga-JH04 PET/CT in patients with different types of cancer, and compared its imaging results with those of 68Ga-FAPI or 18F-FDG PET/CT.
Carcinoma-associated fibroblasts (CAFs) are an integral part of the tumor microenvironment, and fibroblast activation protein (FAP), as a specific marker of CAFs, is overexpressed in more than 90% of epithelial malignant tumors' CAFs, with limited expression in normal tissues, making it an appropriate target for various tumors. Currently, several tracers targeting FAP for diagnostic purposes have been developed, such as 68Ga-FAPI-04, 68Ga-FAPI-02, showing high efficacy in tumor staging and restaging. As an emerging molecule targeting FAP, 68Ga-JH04, in this study, the diagnostic performance of 68Ga-JH04 PET/CT in patients with different types of cancer were observed. Its imaging results were compared with those of 68Ga-FAPI or 18F-FDG PET/CT.
