[Neuroendocrine neoplasms : a new era to the top of multidisciplinarity !]

Neuroendocrine neoplasms are histologically defined by a common neuroendocrine cellular phenotype. These are still considered as rare tumours even though their incidence is increasing. Heterogeneity is everywhere whether in the localization of the primitive cancer, the clinical presentation, the histological classification, the prognosis, as well as in therapeutic options, which clearly justifies specialized multidisciplinary care. Heterogeneity and scarcity explain the still fragmented nature of knowledge in this domain. Thanks to an increase in incidence, a desire for standardization of classification as well as the arrival of major therapeutic advances, such as vectorized internal radiotherapy, the future of neuroendocrine neoplasia seems more than promising and exciting. In our daily clinical practice at CHU Liège, we hope to bring our stone to the building by listing as many cases as possible in national and/or international databases, by centralizing therapeutic discussions within specific multidisciplinary concertations and by participating in multicenter study protocols.
