EGFR and neoplasm: For example, we found that i.t. injection of 4.5 MBq of EGFR-targeted [177Lu]Lu-DOTA-PEG4K(panitumumabPEG5K)-AuNPs or non-targeted [177Lu]Lu-DOTA-PEG4K-AuNPs into s.c. MDA-MB-468 tumours in mice resulted in wide radioactivity distribution ranging from 0 to 2750 Bq and 0–400 Bq, respectively (Yook et al. 2016a).
