#4446 Uncommon ophthalmic presentation of a small bowel neuroendocrine tumour: Case report

Introduction: Neuroendocrine tumours (NETs), including carcinoid tumours, are slow-growing neoplasms commonly originating in the gastrointestinal tract or bronchus, but they can also arise in other sites. Due to their indolent nature, the majority of NETs are diagnosed at an advanced stage, typically to the lymph nodes, liver, or bones.

#4393 Surufatinib plus trans arterial embolisation (TAE) vs. surufatinib monotherapy in neuroendocrine tumour with liver metastasis: Updated results from the prospective, randomised, controlled trial

Introduction: The liver is the main metastasis site for NETs. Surufatinib (SUR), an oral TKI, is standard therapy for advanced NETs. TAE is the primary local intervention for unresectable hepatic NETs.

#4339 Dual threshold contouring for [68Ga]DOTATATE PET and correlation with overall survival (OS) in patients with neuroendocrine neoplasia (NEN)

Introduction: Accurate contouring for [68Ga]DOTATATE PET in NEN is challenging due to differing physiological uptake for the liver, spleen and other organs. This poses a significant problem for absolute thresholding algorithms using a single threshold, even if the threshold is based on liver uptake (as suggested for FDG PET by PERCIST). Improved contouring of PET to measure [68Ga]DOTATATE-avid tumour volume could help clinical translation of this potential biomarker.

#3801 Local treatment of neuroendocrine liver metastases – How effective and safe is stereotactic microwave ablation?

Introduction: The less invasiveness of local ablation techniques such as stereotactic microwave ablation (SMWA) for the treatment of malignant hepatic lesions has made it an attractive alternative to conventional surgical resection.
