#4572 Steroid dosing to prevent tumour flare reaction with 177Lu-DOTATATE

Introduction: Tumour flare reactions including increased pain and small bowel obstruction (SBO) have been reported in patients with somatostatin receptor (SSTR)-positive gastroenteropancreatic neuroendocrine tumours (GEP-NETs) receiving 177Lu-DOTATATE. Retrospective reviews report tumour flare reactions in 6 to 40 percent of high-risk patients receiving 177Lu-DOTATATE and report success with using corticosteroid prophylaxis to prevent tumour flare recurrence with subsequent doses of 177Lu-DOTATATE (Strosberg, et al., 2021; Salner, et al., 2020).
