#4663 CAREFNDR: A phase III, randomised, parallel group, placebo-controlled study to evaluate the efficacy and safety of paltusotine in adults with carcinoid syndrome due to well-differentiated neuroendocrine tumours

Introduction: Paltusotine is a once-daily, oral, nonpeptide, selective SST2 receptor agonist in development for carcinoid syndrome (CS) treatment. In a Phase 2, open-label, dose-ranging study, paltusotine reduced the frequency and severity of CS symptoms and was well tolerated (NCT05361668).

#4642 Establishing a standardised histopathological grading system for mesenteric fibrosis in small intestinal neuroendocrine tumours

Introduction: Mesenteric fibrosis (MF) frequently develops around mesenteric metastasis in small intestinal neuroendocrine tumour (SI-NET) patients. Since MF is not always detected radiologically, histopathological examination is considered the gold standard. However, there is no uniform histopathological scoring system for MF correlated with clinical data.

#4499 Impact of early molecular tumour board inclusion on treatment outcomes in neuroendocrine neoplasms: A retrospective double-centre study

Introduction: The treatment of neuroendocrine neoplasms (NENs) is particularly challenging due to the limited availability of standard therapies. While personalised approaches are revolutionising many areas of oncology, their progress in the field of NENs has been comparatively slower. The integration of molecular tumour boards (MTBs) into clinical practice represents a major advance in oncology, even for rare entities such as NENs.

#4427 Surufatinib combined with hepatic artery infusion chemotherapy (HAIC) as second-line and maintenance therapy for neuroendocrine carcinoma with liver metastases: A single-arm, open-label, single-centre phase II clinical study (SuHaNec)

Introduction: Neuroendocrine carcinoma (NEC) is rare and highly aggressive, and liver metastasis leads to worse outcomes for patients (pts) with limited treatment options and poor prognosis. Surufatinib (SUR) exhibited promising antitumour activity in neuroendocrine neoplasms.

#4418 Endoscopic ultrasound-guided radiofrequency ablation is a safe and efficient treatment of symptomatic insulinomas – A single centre experience of 14 patients

Introduction: The vast majority of insulinomas are benign and less than 20 mm. Surgery is considered as standard treatment, but complications are significant. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) represents a novel and minimally invasive approach.
