Study on the Clinical Application Value of PET Imaging Targeting GPC3 in Hepatocellular Carcinoma
Sponsor: Union Hospital, Tongji Medical College, Huazhong University of Science and Technology
Summary
This is a diagnostic study. Patients were recruited from patients with clinically suspected or confirmed hepatocellular carcinoma and healthy volunteers were recruited for PET/or PET/CT imaging targeting a GPC3-specific probe (in the case of 68Ga-NOTA-aGPC3-scFv) , to observe the reaction of volunteers and patients after injection of drugs, to evaluate the pharmacokinetics in vivo and the efficacy of diagnosis and staging, and to perform PET CT imaging in patients with contraindications. General Information, clinical data, blood routine, liver and renal function, and other imaging data were collected. The final diagnosis was based on the histopathology of biopsy or surgical specimens.

68Ga-aGPC3-scFv/Fab
For pharmacokinetics, healthy volunteer underwent PET imaging targeting GPC3. Blood samples were collected at 25 min, 55 min, and 115 min after imaging agent injection, and urine specimens were collected at 28 min, 58 min, and 118 min after injection to measure radioactivity in blood and urine. PET/MR scans were performed at 30-50 min, 60-80 min, and 120-140 min after injection to understand absorption, distribution, and metabolism. For Cancer patients, subjects should have targeting GPC3 and 18F-FDG PET scans two days apart. Blood tests, liver and kidney function, tumor markers (AFP, etc.), and other biochemical markers must be performed one week prior to and after imaging. Tumor biopsies or surgical specimens should be evaluated histopathologically and immunostained for biomarkers associated with angiogenesis.
