#3073 The Role of Rb as a Prognostic Factor in Grade 3 Poorly Differentiated Neuroendocrine Carcinoma (G3NEC) Treated by First Line Platinum-Etoposide Combination, a Retrospective Study

Introduction: G3NEC are heterogeneous and aggressive diseases which can arise in different organs. Platinum-etoposide combination is used as first line treatment whatever the primary. Rb has been suggested to be a predictive/prognostic factor.

#3055 Dynamics of Changes in Chromogranin A Concentration as a Prognostic Factor Radiopeptide Therapy in Neuroendocrine Tumours

Introduction: Chromogranin A (CgA) is a non-specific marker of neuroendocrine tumors (NET) and its significantly increased level is an unfavorable prognostic factor while the decrease in CgA during biotherapy with somatostatin analogs (SSA) correlates with the increase in profession free survival (PFS).

#3048 Somatostatin Analogs or Active Surveillance in Sporadic Non-Functioning Pancreatic Neuroendocrine Tumors

Introduction: Non-functioning (NF), sporadic pancreatic neuroendocrine tumors (pNETs) have usually an indolent behavior, but sometimes show an unpredictable aggressiveness. Surgery is the first-choice for localized tumors >2 cm. Unresectable or metastatic lesions expressing somatostatin receptors (SSTRs) are treated with Somatostatin analogs (SSAs). No evidence of SSAs efficacy exists in tumors ≤2 cm, for which active surveillance has been proposed.

#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.

#3040 Palliative CT Brachytherapy in Hepatic Metastatic NET

Introduction: Hepatic metastases of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) may induce prognosis relevant complications in an otherwise stable systemic disease after resection of the primary.
