Immuno-PET Imaging and Radioimmunotherapy of ⁶⁴Cu-/¹⁷⁷Lu-Labeled Anti-EGFR Antibody in Esophageal Squamous Cell Carcinoma Model

Abstract

(64)Cu-cetuximab immuno-PET represented EGFR expression levels in ESCC tumors, and (177)Lu-cetuximab radioimmunotherapy effectively inhibited the tumor growth. The diagnostic and therapeutic convergence radiopharmaceutical (64)Cu-/(177)Lu-PCTA-cetuximab may be useful as a diagnostic tool in patient selection and a potent radioimmunotherapy agent in EGFR-positive ESCC tumors.
