ImmunoPET Targeting Trophoblast Cell-surface Antigen 2 (Trop-2) in Solid Tumors
April 14, 2024 updated by: The First Affiliated Hospital of Xiamen University
ImmunoPET Targeting Trophoblast Cell-surface Antigen 2 (Trop-2) in Solid Tumors and Compared With 18F-FDG
The objective of the study is to construct a noninvasive approach 68Ga-THP-Trop2 VHH PET/CT to detect the Trop-2 expression of tumor lesions in patients with Solid tumors and to identify patients benefiting from Trop-2 targeting antibody-drug conjugate treatment.

Detailed Description
As a new trophoblast cell-surface antigen 2 (Trop-2) targeting PET radiotracer, 68Ga-THP-Trop2 VHH is promising as an excellent imaging agent applicable to various cancers.
In this research, subjects with various types of tumors underwent contemporaneous 68Ga-THP-Trop2 VHH and standard-of-care imaging (18F-FDG, 68Ga-PSMA, or 68Ga-DOTATATE PET/CT) either for an initial assessment or for recurrence detection.
Tumor uptake was quantified by the maximum standard uptake value (SUVmax).
The numbers of positive tumor lesions of standard-of-care imaging and 68Ga-THP-Trop2 VHH PET/CT were recorded by visual interpretation.
The diagnostic accuracy of 68Ga-THP-Trop2 VHH was calculated and compared to standard-of-care imaging.
