#4389 The LOLA trial: Phase II trial with combination of cabozantinib plus lanreotide in gastroenteropancreatic (GEP) and thoracic neuroendocrine tumours (NETs) – Interim results of step 1

Introduction: LOLA is an Italian, multicentre, open-label, double cohort, non-randomised, 3-stage, phase 2 trial aiming to assess the safety and activity of the combination of cabozantinib (CABO) + lanreotide (LAN) in patients (pts) with advanced or metastatic GEP and unknown primary NETs with Ki-67 > 10% or thoracic NET. In NETs sunitinib is the only TKI approved in advanced pancreatic NETs. While CABO has been reported superior to sunitinib in renal cancer its role in NETs is still investigational.

#4242 Sequential Everolimus and Sunitinib treatment in progressive, advanced, pancreatic NENs: Real-world data from the Belgian Group of Digestive Oncology DNET & NETwerk

Introduction: Everolimus and Sunitinib are often used consecutively for advanced, progressive, well-differentiated pancreatic neuroendocrine tumors (pNET), but to date no data on the optimal sequence is available.

#4119 Interim analysis of LANTana: Phase Ib study investigating up-regulation of somatostatin receptor-2 (SSTR2) with the de-methylating agent ASTX727 to allow [177Lu]Lu-DOTA-TATE in metastatic neuroendocrine tumors (NETs)

Introduction: To be suitable for [177Lu]Lu-DOTA-TATE, SSTR2 must be present on tumor surface as per positive uptake on [68Ga]Ga-DOTA-TATE-PET/CT. SSTR2 promoter methylation reduces SSTR2 expression; this can be reversed using a demethylating agent.

#3870 Small bowel neuroendocrine tumor with carcinoid heart disease

Introduction: Patients with neuroendocrine tumors are often misdiagnosed, at least for the first stage of the disease. In fact, carcinoid syndrome is the clinical expression of the vasoactive substances produce. Carcinoid heart disease is a hazardous and irreversible complication especially in late identified cases.

#3838 Subgroup analysis of ORR and PFS of the SEQTOR study (GETNE 1206) – Everolimus followed by Streptozotocin (STZ)-5FU upon progression or the reverse sequence, in advanced progressive panNETs

Introduction: Previous global results of ORR and PFS1 have been presented. The best treatment (Tx) sequence between STZ-5FU and everolimus (EVE) in patients (pts) with advanced and progressive panNETs is not yet well established.
