Diagnostic and therapeutic role of endoscopy in gastroenteropancreatic neuroendocrine neoplasms.

Guidelines for the management of gastroenteropancreatic neuroendocrine tumours (including bronchopulmonary and thymic neoplasms). Part I-general overview.

The incidence of neuroendocrine tumours of the gastroenteropancreatic system seems to have increased during the past decade. New diagnostic and therapeutic procedures have aroused the interest of physicians, though most see very few cases of such diseases. A group of members of the Nordic Neuroendocrine Tumour Group decided to compile some guidelines to facilitate the diagnosis and treatment of...

Identification of primary tumors in patients presenting with metastatic gastroenteropancreatic neuroendocrine tumors.

BACKGROUND Patients with gastroenteropancreatic neuroendocrine tumors often present with metastases. Identification of the primary tumor is important for operative management, and therefore we sought to determine our success at identifying primary tumors with diagnostic testing and operative exploration. METHODS A clinical neuroendocrine tumor database was reviewed to identify patients presen...

Role of Endoscopic Ultrasound in Gastroenteropancreatic Neuroendocrine Tumors and Update on Their Treatment

The gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are rare tumors and include all tumors arising from the gastrointestinal (GI) or pancreatic neuroendocrine cells. They can occur anywhere in the GI tract with the small intestine, pancreas and rectum being the common GI sites. Because of nonspecific symptoms they are difficult to diagnose and diagnosis is often delayed by years. Adva...

New therapeutic approaches to metastatic gastroenteropancreatic neuroendocrine tumors: A glimpse into the future

Neuroendocrine (NE) gastroenteropancreatic tumors are a heterogeneous group of neoplasias arising from neuroendocrine cells of the embryological gut. Their incidence have increased significantly over the past 3 decades probably due to the improvements in imaging and diagnosis. The recent advances in molecular biology have translated into an expansion of therapeutic approaches to these patients....
