ABSTRACT
THE SPECTRUM OF NEUROENDOCRINE TUMOR PATHOLOGY IN THE GASTROINTESTINAL TRACT
G. Klöppel
Department of Pathology, University of Kiel, Kiel, Germany
Neuroendocrine tumors of the gastrointestinal tract are a heterogeneous population of neoplasms differing from each other in their secretory and functional properties, pathogenetic mechanisms, related clinical syndromes, pathological associations and prognosis. Previous classifications insufficiently considered all newly established morphological, functional and biological features of these tumors. The lecture, therefore, discusses the new WHO classification, which attempts to consider the morphological, functional and biological features of gastrointestinal neuroendocrine tumors. The focus will be on tumors of the stomach, duodenum and jejunum.
