#3080 Impact of Multimodal Perioperative Treatment in Patients with Resected Non-Metastatic Grade 3 Neuroendocrine Neoplasms (NEN G3)

Introduction: Patients with grade 3 neuroendocrine neoplasm (NEN G3) have a limited prognosis. Even in a non-metastatic stage, the risk of recurrence after surgery is high. Multimodal perioperative treatment, including chemotherapy and/or radiotherapy in an adjuvant or neoadjuvant setting, has improved the prognosis in numerous tumor entities; however, it has not been systematically evaluated in NEN G3 so far. Nevertheless, perioperative chemotherapy is generally recommended in most current treatment guidelines for NEN G3.

#2879 Lung Neuroendocrine Tumors: Experience of Medical Oncology Department of Hospital 1st November 1954 Oran

Introduction: Lung neuroendocrine tumors account for 25% of all neuroendocrine tumors. It is a heterogeneous group that meets morphological criteria; immunohistochemical and molecular; defining 4 groups: Typical and atypical carcinoid tumors, neuroendocrine carcinomas with large cell and small cells. Carcinoid syndrome is rare in these tumors and the treatment is based on surgery for localized forms and multimodal treatment for metastatic forms.
