#4230 Grade ≥3 subacute haematological toxicity with 177Lu-DOTATATE PRRT – Results from LUMEN study
Introduction: Bone marrow toxicity during peptide receptor radionuclide therapy (PRRT), results from radiation damage to haematopoietic tissue. Prospective comprehensive data on subacute haematological toxicity are scarce.

Introduction: Scottish National PRRT Service delivers 177Lu-Dotatate nationally at the Beatson West of Scotland Cancer Centre (BWoSCC). The NETTER-1 trial (Strosberg et al 2017) significantly changed the treatment and management of patients with gastroenteropancreatic NET (GEPNET). 177Lu-Dotatate demonstrated superiority in progression free survival (PFS) in patients with G1 and 2 midgut neuroendocrine tumors (NET). 177Lu-Dotatate 7.4 GBq 8 weekly gave 65% estimated progression free survival (PFS)at 20 months versus 10.8 % with 60mg octreotide intramuscularly 4 weekly (Strosberg et al 2017). Prior to this study everolimus was the most common 2nd line treatment for SBNET with a PFS of 14 months (Puscuddo et al 2017).
