Neuroendocrine tumors are a rare and heterogeneous group of neoplasms with different malignant potential. They often metastasize to the liver require active combined therapy. For unresectable neuroendocrine metastases, transplantation has become potential definitive treatment due slow growth clinical course metastatic process. We conducted review relevant literature, criteria for including excl...

OBJECTIVE Description of some of the clinical pathological characteristics of neuroendocrine tumors of the gastroenteropancreatic tract in Brazilian patients. INTRODUCTION Neuroendocrine tumors arise in many organs and share common pathological features. In 2010, the World Health Organization published a new classification for neuroendocrine tumors using a three-tiered system that applies the...

Pancreatic neuroendocrine tumors are usually indolent (slow-growing) by nature and develop over the course of many years. Pancreatic neuroendocrine tumors are usually more indolent, with better prognosis than adenocarcinoma of the pancreas (Carriaga & Henson, 1995). However, aggressive, fast growing pancreatic neuroendocrine tumors exist and different types of pancreatic neuroendocrine tumors e...

Neuroendocrine tumors are rarely seen in the breast. They are commonly located in the gastrointestinal tract and the lungs. These tumors of the breast may be purely neuroendocrine or neuroendocrine diff erentiated. Some breast tumors may have neuroendocrine foci. The clinical signifi cance of these tumors are unclear. However, they are thought to have no relation with the prognosis and patient ...
