Holmium-166-radioembolization in NET After Lutetium-177-dotatate; an Efficacy Study

Overview

Patients with gastroenteropancreatic neuroendocrine tumours (NET) often die from intrahepatic disease or are excluded from liver-directed treatment because of extrahepatic disease. Adjuvant liver-directed treatment is warranted to control both intra- and extrahepatic disease. Patients with liver metastases of NET will be included in this study (n = 30-48).The efficacy and toxicity of adjuvant 166Ho-radioembolization (166Ho-RE) after systemic 177Lu-dotatate will be studied in a non-comparative phase II study. The study is an interventional, treatment, non-randomized, open label, non-comparative, phase II study. 166Ho-RE will be performed via a catheter during angiography.
