#4403 Ki-67 index cut-off values and survival prognostication in neuroendocrine neoplasms: Machine learning-based insights

Introduction: The current grading system for gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) is based on Ki-67 index and/or mitotic rate. By definition, high-grade NEN (neuroendocrine tumour grade 3 [NET G3] and neuroendocrine carcinoma [NEC]) have a Ki-67 >20%, while NET G1 have a Ki-67

#3672 Impact of everolimus starting dose on antiproliferative efficacy in patients with neuroendocrine tumors – Experiences from a tertiary referral center

Introduction: Everolimus is approved at a full dose of 10 mg daily for the treatment of advanced neuroendocrine tumors (NETs) but associated with relevant toxicities. Hence dose reductions are a frequent event in clinical practice.

#2097 Oral Ondansetron Offers Effective Symptomatic Bridging for Carcinoid Syndrome Refractory to Somatostatin Analogues

Introduction: Somatostatin analogues (SSA) are standard for symptomatic patients with neuroendocrine tumours (NETs). However, most patients experience tachyphylaxis, and limited options exist for this refractory carcinoid syndrome (RCS). Recently, ondansetron has been associated with reduction of bowel movement in a small series.
