Abstract
The understanding of neuroendocrine neoplasms has evolved significantly since their initial descriptions in the 1800s to early 1900s. In the gastroenteropancreatic system, this group of malignant tumors is subdivided into well and poorly differentiated neuroendocrine neoplasms based on morphologic, proliferative and biologic differences. However, it has become increasingly apparent that well-differentiated neuroendocrine tumors are not a homogeneous group. Attempting to better predict outcome of these tumors has been the motivation behind numerous proposed classification systems, the evolution of which culminated with the currently used system, the ENETS/WHO classification. Herein, we review the genesis of this classification system and some of its shortcomings. In addition, we discuss some of the most recent proposals that suggest modifications to the current system.
期刊介绍:
International Journal of Endocrine Oncology is a quarterly, peer-reviewed journal that helps the clinician to keep up to date with best practice in this fast-moving field. The journal highlights significant advances in basic and translational research, and places them in context for future therapy. The journal presents the latest research findings in diagnosis and management of endocrine cancer, together with authoritative reviews, cutting-edge editorials and perspectives that highlight hot topics and controversy in the field. Independent drug evaluations assess newly approved medications and their role in clinical practice. The journal welcomes the unsolicited submission of article proposals and original research manuscripts.
