Safety and Effectiveness of a New 18F Labeled Fibroblast Activation Protein Probe for Early Tumor Detection Including Lung, Pancreatic, Neuroendocrine, and Thyroid Cancers

What this Trial Is About

Researchers are evaluating the safety and effectiveness of a new molecular probe called 18F-FAPI-YQ104, which targets fibroblast activation protein FAP, for early tumor diagnosis. This observational study focuses on patients with lung cancer, pancreatic cancer, neuroendocrine tumors, and thyroid cancer. The goal is to verify how well this probe works in detecting tumors during clinical use. Participants will receive an intravenous injection of the 18F-FAPI-YQ104 probe followed by a PET-CT examination to capture detailed images of tumor lesions. The study will observe the probes uptake in tumor sites, measured by SUVmax values 60 minutes after administration. No additional treatment is given instead, the study monitors the imaging results to assess the probes diagnostic potential. During the study, participants will undergo PET-CT scans and other imaging tests such as CT or MRI. Researchers will evaluate the images to measure tumor activity and probe uptake. Safety assessments include checking kidney and liver function, blood counts, and monitoring for allergic reactions. The study will last from April 2025 to March 2026 and includes adults aged 18 to 75 years who have confirmed tumors and meet health criteria.
