[Neuroendocrine well-differentiated pancreatic tumors]. / Tumeurs neuro-endocrines bien différenciées du pancreas.

Neuroendocrine pancreatic tumors are rare tumors which require specific diagnosis and management. They are characterized by complex histopathologic criteria, large differences in secretory profile and évolutivity, and be associated to hereditary endocrine disease as NEM1 or VHL. Therapeutic strategy is currently discussed throught the regional or national pluridisciplinary workups organized by the 17 experts centers of the French RENATEN network. Treatment of these tumors requires the optimal control of hormonal secretory features for functioning neuroendocrine tumors while antiproliferative treatments are indicated for metastatic large or/and progressive tumors. Their optimal treatment may include locoregional procedures as chemoembolization, radiopeptidé therapy, chemotherapy, targeted therapies and clinical trials.
