#3044 Efficacy of Alkylating Agent Re-challenge after Therapeutic Pause in Metastatic Pancreatic Neuroendocrine Tumors (PanNET)

Introduction: Temozolomide (TMZ) and dacarbazine (DTIC) are alkylating agents (ALK) with antitumor efficacy in metastatic PanNET. Rechallenging ALK following prior efficacy is commonly performed but has not been evaluated.

#2955 Development of an EORTC Quality of Life Questionnaire for Patients with Pancreatic Neuroendocrine Tumours: Phases 1-3

Introduction: Measuring quality of life (QoL) in Pancreatic Neuroendocrine Tumours (pNET) involves assessing issues from symptoms, disease and treatment. The validated gastrointestinal NETs module (EORTC QLQ-GINET21) is used with EORTC QLQ-C30 but there are concerns it inadequately measures QoL in pNET.

#2947 Al18F-NOTA-Octreotide PET Imaging of the Somatostatin Receptor: First Comparison with 68Ga-DOTATATE in Neuroendocrine Tumor Patients

Introduction: Practical and economic challenges limit the widespread use of 68Ga-labeled somatostatin analog (SSA) PET, the current standard for somatostatin receptor imaging. A promising 18F-labeled SSA, Al18F-NOTA-octreotide (Al18F-OC), has recently been introduced.

#2940 Avelumab in Unresectable/Metastatic, Progressive, Poorly Differentiated, Grade 3 Neuroendocrine Carcinomas (NECs)

Introduction: Poorly differentiated, G3 NECs are associated with poor outcomes and have no effective treatment options apart from cytotoxic chemotherapy.

#2935 Prior Surgical Resection and Ga-68-DOTANOC PET/CT Imaging-Based Parameters: Do These Impact Outcomes in Grade II Gastroentero-Pancreatic Neuroendocrine Tumors (GEP-NETs)

Introduction: Grade 2 GEP-NETs have inherent tumor heterogeneity seen with positive expression of somatostatin (SSTR) and glucose (GLUT) receptors. Prior surgical resection and imaging parameters on Ga-68 DOTANOC PET/C are well-established variable impacting prognosis in well-differentiated grade 1 NETs. Since the degree of differentiation is variable in Grade 2 NETs, these parameters have not been studied.
