Carcinoid Tumors of the Gastrointestinal Tract: Trends in Incidence in England Since 1971

Abstract

Large increases in the incidence of GI-NETs were observed, along with changes in anatomical distribution. Such changes may partly reflect changes in classification or improved detection through the increased use of endoscopy and imaging techniques. In view of the magnitude of these changes, particularly for gastric tumors, further studies to examine the underlying etiology of these changes are urgently indicated.
