#3045 Reliability and Agreement of Radiological and Pathological Tumor Size in Patients with MEN1-Related Pancreatic Neuroendocrine Tumors: Results from a Population-Based Cohort

Introduction: Pancreatic neuroendocrine tumors (pNETs) are the most lethal manifestation in patients with multiple endocrine neoplasia type 1 (MEN1). Tumor size is still regarded as the main prognostic factor and therefore used for surgical decision making.

#2881 Patient-Derived Tumor Xenograft Combined with Chemotherapy Drug Sensitivity Test in a Patient with Pancreatic Neuroendocrine Carcinoma

Introduction: Pancreatic neuroendocrine carcinoma (p-NEC) with liver metastasis has a poor prognosis. The treatment is mainly chemotherapy which is now still a huge challenge on NEC with high ki-67 index.

#2844 Rectal Neuroendocrine Tumor with Chromogranin Expression Is Associated with Aggressive Clinical Behavior and Worse Prognosis

Introduction: Although rectal neuroendocrine tumors (NETs) with L-cell phenotype and small tumor size generally had better clinical behavior, the new 2019 WHO classification classified all rectal NETs are malignant without considering L-cell phenotype and small tumor size. Therefore, identifying biomarkers of rectal NETs is important to stratify the clinical behavior of rectal NETs.

#2750 Progression-Free Survival and Clinical Outcomes with Long-Term Use of Telotristat Ethyl in US Clinical Practice

Introduction: Treatment of advanced neuroendocrine tumors aims to relieve symptoms and suppress tumor growth. Primary findings from the TELEACE study suggested telotristat ethyl (TE) may reduce tumor size and impact tumor growth.
