[Neuroendocrine tumors in daily gastroenterology and endoscopy - a practice manual]. / Neuroendokrine Tumoren in der täglichen gastroenterologischen und endoskopischen Praxis ­ ein klinisch orientierter Leitfaden.

ABSTRACT

Neuroendocrine tumors of the gastrointestinal tract (GI-NET) are rare tumors. Functional tumors with hormonal syndromes (e. g., insulinoma, gastrinoma) are less common than non-functional tumors, which usually have an indolent course. Therapy for GI-NET is multimodal, including endoscopic or surgical procedures aiming at complete removal of tumor tissue. Patients in later stages may benefit from interventional radiology or medical therapy. This article gives an overview regarding the key aspects of GI-NET therapy in daily gastroenterology practice with emphasis on endoscopic diagnosis and therapy.
