About

A prospective cohort imaging study in a single institution to evaluate 68Ga- FAPI-46 and 18F-FDG PET/CT imaging for detecting recurrent tumor lesions in patients of ovarian cancer with CA125 elevation from complete response after therapy

Full description

Ovarian cancer is the eighth most common cancer worldwide in females and usually diagnosed at an advanced stage. Serum cancer antigen 125 (CA125) is widely used in ovarian cancer. An elevation in CA125 levels can precede a clinically apparent recurrence by 3 to 6 months and 18F-FDG PET/CT can modify management in approximately half of these patients. However. 18F-FDG PET/CT may yield false negative results. 68Ga-FAPI-46 PET/CT shows potential here. This study is to assess the diagnostic performances of 68Ga-FAPI-46 and 18F-FDG PET/CT for ovarian cancer recurrence in patients with CA125 elevation from complete response after therapy.
