#4329 Multivariate survival analyses of 544 advanced high-grade digestive neuroendocrine neoplasms (NET G3 and NEC) given first-line chemotherapy (NORDIC NEC 2)

Introduction: Digestive high-grade neuroendocrine neoplasms (HG-NEN) are rare and consist of neuroendocrine tumours G3 (NET G3) and neuroendocrine carcinomas (NEC). They differ in clinical and molecular characteristics, response to treatment and prognosis. Limited prospective data are available on prognostic factors for survival in patients given first-line chemotherapy outside of clinical trials.

#2831 Immunohistochemical Profile of Digestive Neuroendocrine Neoplasms: A Retrospective Analysis in a Single Algerian Institution

Introduction: Neuroendocrine Noplasms (NEN) are rare tumours, but their incidence is clearly increasing in our country due to the improvement of diagnostic means, in particular the generalization of immunohistochemical techniques. The digestive location represents more than 70% of the cases. The anatomopathological study enables to classify the NEN in different prognostic grades according to the degree of differentiation, mitotic index and Ki67.
