Updating the management of patients with rectal neuroendocrine tumors.

Rectal neuroendocrine tumors (NETs) account for approximately one-third of all digestive NETs, with an increasing incidence and good overall prognosis. Although recent guidelines have been published, endoscopic techniques have expanded substantially and the most recent reports should be taken into account for clinical practice. The objectives of this report were to review the latest advances on prognosis, pre-interventional explorations, treatment-with particular focus on endoscopy-and surveillance of well-differentiated rectal NETs, excluding poorly differentiated and metastatic tumors. © Georg Thieme Verlag KG Stuttgart · New York.
