Comparing FAPI and FDG PET Imaging in Cancer Patients

Application of FAPI and FDG PET Imaging in Patients With Different Types of Cancer

Observational Daping Hospital and the Research Institute of Surgery of the Third Military Medical University · NCT06284070

This study is testing if a new type of cancer imaging called FAPI is better than the usual FDG PET scan for helping doctors find and diagnose different kinds of cancer in adults.

What this trial studies

This observational study aims to evaluate the effectiveness of fibroblast activation protein inhibitors (FAPI) compared to traditional 18F-FDG PET imaging in diagnosing various types of cancer. It will involve adult patients with suspected or newly diagnosed malignant tumors who will undergo both imaging techniques within a week. Clinical data, including tumor markers and imaging results, will be collected and analyzed to assess the performance of these imaging modalities in identifying primary and metastatic lesions. The study is set to run from January 2024 to December 2029.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with suspected or newly diagnosed malignant tumors.

Not a fit: Patients who are pregnant or have conditions that prevent them from undergoing imaging will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accurate imaging alternative for cancer diagnosis, potentially improving patient outcomes.

How similar studies have performed: While the use of FAPI in imaging is emerging, this specific comparative approach has not been widely tested, making it a novel investigation.
