Zusammenfassung
Neuroendokrine Tumore (NET) des Magens sind selten. Klinisch werden sie in Typ 1 bis 3 unterteilt. Histologisch werden diese Tumoren nach der WHO 2000 klassifiziert. NET Typ-1 können im Rahmen einer chronisch atrophen Gastritis als einzelne oder multiple, kleine Tumoren auftreten. Die Prognose dieser Tumoren ist sehr gut. Diese Tumoren als Todesursache werden nicht beschrieben. NET Typ-2 werden im Rahmen des MEN1-Syndroms beobachtet. Diese Tumoren sind aggressiver und können Metastasen setzen. Meistens ist aber die Todesursache bei MEN-1-Syndroms ein neuroendokriner Tumor des Duodenums oder Magens. NET Typ-3 treten sporadisch ohne zusätzliche Magenpathologie auf. Diese Tumoren treten früh ohne Geschlechtsbevorzugung auf. Bei aggressivem Verlauf setzen sie Metastasen und haben insgesamt eine schlechte Prognose. Ein aggressive chirurgische Therapie ist zu empfehlen.
Summary
Gastric neuroendocrine tumours (NET) are rare. Clinically they are classified in tumours type 1 to 3. The histological classification is according to the WHO 2000 classification for endocrine tumours. NET type 1 occur in coincidence with chronic atrophic gastritis, as single or multiple small tumours. The prognosis of type 1 tumours is excellent, with no tumour related death reported during follow-up. NET type 2 are part of the MEN-1 syndrome. These tumours may be more aggressive and even develop metastasis. However, in most patients with MEN-1 the prognosis is due to other manifestations of the disease as duodenal or pancreatic neuroendocrine tumours. Gastric neuroendocrine tumours type 3 are sporadic tumours without relationship to other gastric pathology. They tend to occur earlier, without sex preference. These tumours may develop an aggressive course, with metastatic disease and an overall poor prognosis. Thus, aggressive surgical therapy is recommended.
