Brief Summary

This is a prospective, single-center, single arm, open label study to evaluate the performance of 68Ga-FAPI-46 for the diagnosis of primary and metastatic lesions of lung cancer with comparison to 18F-FDG PET.

Conditions

Lung Cancer

Keywords

68Ga-FAPI-46; Lung Cancer

Outcome Measures

Primary Outcomes (1)

• To define the diagnostic performance 68Ga-FAPI PET

  To evaluate the diagnostic performance (sensitivity, specificity, accuracy) of the 68Ga-FAPI-46 PET scan for identification and staging of lung cancer with comparison to 18F-FDG PET. Histopathology and clinical follow-up will be used as truth standard.

  Through study completion, 2 years

Secondary Outcomes (1)

• To determine the safety profile of 68Ga-FAPI PET

  Up to 7 days post injection with 68Ga-FAPI-46

Study Arms (1)

68Ga-FAPI-46 PET Scan

EXPERIMENTAL

A single-center prospective interventional single-arm clinical trial. All patients will undergo whole-body 68Ga-FAPI-46 PET scan within two weeks before or after 18F-FDG-PET. Injected activity of 68Ga-FAPI-46 is limited to 100-250 MBq per examination.

Diagnostic Test: 68Ga-FAPI-46

Interventions

68Ga-FAPI-46 DIAGNOSTIC_TEST

68Ga-FAPI-46 is a radioactive diagnostic agent for PET imaging in the detection of Fibroblast Activation Protein (FAP) positive tumor cells in cancer patients
