GPC3-Targeted PET/CT in Hepatocellular Carcinoma

This study is designed to investigate GPC3-targeted PET/CT as a noninvasive approach for detecting tumor lesions in patients with suspected or histologically/clinically confirmed hepatocellular carcinoma. In this research, eligible patients will undergo contemporaneous GPC3-targeted PET/CT and 18F-FDG either for initial assessment or for metastases or highly suspected recurrence detection. Tumor uptake will be quantified by the maximum standardized uptake value (SUVmax). Positive lesions detected by 18F-FDG PET/CT and GPC3-targeted PET/CT will be recorded by visual interpretation and compared. Imaging findings will be compared with pathological result and/or with contrast-enhanced MRI.

Inclusion criteria

• Adult patients (aged 18 years or older);
• Patients with suspected, newly diagnosed, or previously treated hepatocellular carcinoma(supporting evidence may include imaging findings and pathology report);
• Patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.
• Estimated life expectancy of more than 3 months, as assessed by the investigator, and ability to comply with study procedures and scheduled visits;

Exclusion criteria

• The inability or unwillingness of the research participant or legal representative to provide written informed consent.
• Inability to complete PET/CT imaging.
