#4035 The safety and efficacy of surufatinib for the treatment of advanced neuroendocrine tumors: A prospective, multicenter, real-world study

Introduction: Surufatinib (a small-molecule inhibitor of VEGFR1-3, FGFR1, and CSF-1R) has exhibited encouraging antitumor activity for the treatment of advanced neuroendocrine tumors (including NET and NEC) in multiple registration studies.

#3949 Real-world study of Surufatinib combined with hepatic artery infusion chemotherapy (HAIC) for high-grade neuroendocrine neoplasm

Introduction: Current therapeutic schedules of liver metastasis-dominated extrapulmonary high-grade neuroendocrine neoplasm (HG-NEN) have limited clinical benefits and liver metastasis progression is the main cause of death. Surufatinib (SUR, a selective VEGFRs, FGFR1 and CSF-1R inhibitor) showed promising antitumor activity in neuroendocrine neoplasm.

#3848 LITESPARK-015 cohort B1 – A phase 2 open-label study of Belzutifan (a HIF-2α inhibitor) monotherapy in patients with von Hippel-Lindau (VHL) disease–associated tumors

Introduction: Patients (pts) with von Hippel-Lindau (VHL) disease need novel targeted therapies. Hypoxia-inducible factor 2α (HIF-2α) is a key oncogenic driver in VHL disease. Belzutifan (MK-6482), a HIF-2α inhibitor, has shown antitumor activity in pts with advanced renal cell carcinoma (RCC) and pancreatic neuroendocrine tumors (pNETs); more data are needed in VHL disease–associated localized tumors.

#3705 First results from IEO 676 clinical study of PRRT in neuroendocrine tumors – Is there still a space for Y-90-DOTATOC?

Introduction: IEO 676 is a prospective phase II study of Peptide Receptor Radionuclide Therapy (PRRT) with Y-90-DOTATOC in progressive G1, G2, G3, neuroendocrine patients. PRRT has been in use since the late 1990s, with the introduction of 90Y-DOTATOC, which allowed objective responses in 10-30% of treated patients.
