RESULTS PCa cell culture studies confirmed adequate RAGE-targeting with 64Cu-Cy5-G4-CML with KD between 360 and 540 nM as measured by flow cytometry. In vivo PET-CT images of PCa xenografts revealed favorable kinetics, rapid blood clearance, and a non-homogenous, enhanced uptake in tumors, which varied based on cell type and tumor size with mean uptake between 0.5 and 1.4%ID/g. RAGE quantification of human samples confirmed increased RAGE uptake corresponding to increased Gleason scoring. CONCLUSIONS Our study has shown that RAGE-targeted cancer imaging is feasible and could significantly impact PCa management.PURPOSE The purpose of this study was to compare dynamic 18F-FGln PET/CT images of healthy subjects and cancer patients and explore the best imaging phase for different cancers. METHODS Thirteen healthy volunteers and 31 cancer patients separately underwent 18F-FGln and 18F-FDG PET/CT scans within 1 week. The distributions of 18F-FGln and 18F-FDG in the whole body and the tumor avidity were analyzed and compared. The tumor maximum standardized uptake values (SUVmax) and tumor-to-nontumor SUV ratio (SUR) of 18F-FGln/PET at different scan phases were compared. RESULTS Compared to the healthy subjects, the cancer patients had lower 18F-FGln activity (SUVmean) in most normal organs, especially in the lung, muscle, spleen, and heart (p  less then  0.05). Additionally, the FGln-avid tumors did not necessarily manifest as FDG-avid and vice versa. Overall, among the 31 primary malignant lesions confirmed by biopsy or postoperative pathological analysis, 29 showed increased radioactive uptake on all 18F-FGln PET/CT imaging phases. The peak of SUVmax in breast and thyroid cancers was within 10 min, while in lung cancers, the plateau of SUVmax was within 30 min to 60 min.
