[A TNM classification for digestive endocrine tumors of midgut and hindgut: proposals from the European Neuroendocrine Tumor Society (ENETS)].

The recent proposals for a TNM classification of midgut and hindgut endocrine tumors made by the European Neuroendocrine Tumor Society (ENETS) are presented and commented. Certain particular points, such as the evaluation of the risk of malignancy of an endocrine tumor discovered fortuitously after appendicectomy and the indication of an additional surgical treatment, are developed. Finally, other questions frequently asked about digestive endocrine tumors are addressed.
