Abstract

Meta-[131I]iodobenzylguanidine ([131I]MIBG), used for neuroblastoma treatment, binds to the noradrenaline transporter (NAT). After NAT gene transfection, other tumour types might be treatable with [131I]MIBG. At 14 MBq, carrier-added [131I]MIBG (1110 MBq / mg) delayed tumour regrowth in NAT gene-transfected xenografts by 39-days, while no-carrier-added [131I]MIBG ( > 104 GBq / mg) cured 100% of tumours.
