#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.

#2730 FOLFIRINEC, A Multi-Center, Randomized, Comparative Phase II Study of FOLFIRINOX vs Platinum-Etoposide as First Line Treatment for Metastatic Neuroendocrine Carcinoma of Gastroenteropancreatic or Unknown Origin, Associated with Molecular Profiling

Introduction: Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine carcinoma (NEC) are rare diseases with a poor prognosis. FOLFIRINEC is a multicenter comparative phase II study of mFOLFIRINOX vs platinum-etoposide (PE) as first line treatment for metastatic G3 NEC of GEP or unknown origin.

#2699 Dacarbazine- or Temozolomide-Based Chemotherapy in Metastatic Digestive Neuroendocrine Carcinomas in Post First-line Chemotherapy: A Retrospective Multicentric Study of the French Group of Endocrine Tumours (GTE)

Introduction: First-line chemotherapy in metastatic neuroendocrine carcinomas (NEC) is based on etoposide and platinum. However, there is no standard for second line treatment.

#1845 Mismatch Repair (MMR) Protein Expression is Uncommon in Poorly Differentiated Neuroendocrine Carcinoma

Introduction: Microsatellite instability (MSI) has been reported to occur in a significant proportion of neuroendocrine carcinoma (NEC) and mixed adenoneuroendocrine carcinomas (MANEC) (11 out of 89 cases, Sahnane et al, ERC 2015). It might be predictive of response to immunotherapy.

#1707 Implication of Neuropilin-2 in the Progression of Small Intestinal Neuroendocrine Tumors: Towards a Promising Therapeutic Target?

Introduction: Small intestinal neuroendocrine tumors (siNETs) are rare tumors that raise several clinical and therapeutic challenges. Current treatments are not efficient, in part because of a poor understanding of their mechanisms of progression. We recently highlighted some axon guidance molecules (AGMs) that might be implicated in the progression of siNETs. Among them, we are currently focusing our efforts on the semaphorin 3F receptor neuropilin-2 (NRP2).
