#3403 Trends in chemotherapy use in neuroendocrine neoplasms: One step beyond guidelines

Introduction: The therapeutic landscape of neuroendocrine neoplasms (NENs) is constantly evolving. Current guidelines reflect the complexity of treatment sequences and mainly incorporate evidence from phase 3 clinical trials. Chemotherapy (CT) is a valuable option for patients with lung, pancreatic, and high-grade NENs, but proper phase 3 randomized studies are an unmet need. Nevertheless, several phase 2 studies with CT have been presented and published in the last year, with impact in both clinical practice and guidelines.

#3134 Ipilimumab and Nivolumab in patients with neuroendocrine carcinomas: Two case reports

Introduction: Neuroendocrine carcinomas (NEC) have a poor prognosis and there is no standard second-line treatment. Two studies, DART SWOG 1609 and CA209-538, have shown activity of the combination of Ipilimumab and Nivolumab.

#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.

#2875 Immunotherapy as Second-line Treatment in Grade 3 Neuroendocrine Carcinomas: A Prospective Case Series from an ENETS Center of Excellence

Introduction: Metastatic WHO grade 3 extra-pulmonary neuroendocrine carcinomas (EP-NEC) have a poor prognosis and optimal treatment after first-line platinum-etoposide chemotherapy remains unclear. A recent, small phase II study combining ipilimumab and nivolumab showed promising results

#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.
