Everolimus after hepatic arterial embolisation therapy of metastases from gastrointestinal neuroendocrine tumours: The FFCD 1104-EVACEL-GTE phase II study

Abstract Background Hepatic arterial embolisation therapy (HAET) is a treatment of liver metastases of gastrointestinal neuroendocrine tumours (GI-NETs). HAET increases circulating vascular endothelial growth factor levels. Everolimus is a treatment in NETs that may have antiangiogenic activity. Methods This phase II study was conducted in patients with predominant and progressive liver metastases from GI-NETs. Everolimus was initiated 7–30 days after HAET. The hypothesis was that everolimus after HAET would increase hepatic progression-free survival (hPFS) rate at 24 months from 35% to 50%. Results Among the 74 patients included, 88% had small-bowel primary tumour, 43% had grade I and 57% …
