Only marginal amounts of activity were detectable in the kidneys for 152Tb-PSMA-617 and 177Lu-PSMA-617 at 2 h p.i., with complete wash-out at 15 h p.i. No accumulation of radioligand was observed in the PC-3 flu tumors on the left shoulder or any other non-target organ, thus indicating PSMA-specific tumor uptake (Fig. 2). This evidence concerns the gene FOLH1 and neoplasm.
