More recently, Dickerson and co-workers [25] assessed the performance of a humanized 89Zr-labeled anti-GPC3 antibody (89Zr-αGPC3H) versus its murine version (89Zr-αGPC3M), employed in the previously cited paper by Sham et al. [20] for immuno-PET imaging in a mouse model of HCC. This evidence concerns the gene GPC3 and hepatocellular carcinoma.
