Compared to other PSMA-binding ligands, the tumour uptake of 212Pb-NG001 after 1 h was similar to that of 203Pb-L2 but considerably higher than that reported for 203Pb-CA012 and for most studies of 177Lu-PSMA-617 (Figure 2 and Table 3) [5,24,30,31,32]. This evidence concerns the gene FOLH1 and neoplasm.
