Trophoblast Cell-Surface Antigen 2 (Trop-2) Targeted PET/CT in Recurrent and Metastatic Thyroid Cancer

Description:

In this study, we comprehensively evaluated the clinical utility of Trop2 PET/CT (68Ga-MY6349 PET/CT) imaging for detecting recurrent and metastatic thyroid cancer, and the results were compared with those of 68Ga-FAPI PET/CT. The primary objective of this study was to evaluate the patient-based sensitivity of 68Ga-MY6349 PET/CT in detecting recurrent and metastatic thyroid cancer. The secondary objectives included its overall specificity, lesion-based diagnostic performance, comparative tumor uptake relative to 68Ga-FAPI PET/CT, and the impact on clinical management.
