Management of neuroendocrine tumors
American Journal of Health-System Pharmacy, 2016Current strategies for managing neuroendocrine tumors (NETs) in adult patients are reviewed, with a focus on medication safety concerns.NETs usually originate in the gastrointestinal or bronchopulmonary tract. Symptoms due to hormonal hypersecretion often occur in patients with foregut or midgut NETs or liver metastases.

Pancreatic neuroendocrine tumors
Disease-a-Month, 2013Pancreatic neuroendocrine tumors (PNETs) have an incidence of approximately 1 per 100,000 individuals per year, and account for 1–2% of all pancreatic tumors. The annual incidence in the United States is about 3.65 per 100,000 population. Although they may manifest at any age, they most often occur in the fourth to sixth decades of life. Most PNETs are

Neuroendocrine tumors of the pancreas
Current Opinion in Oncology, 2012Pancreatic neuroendocrine tumors (PNETs) are rare tumors, with an incidence of one per 100, 000 individuals per year, and they account for 1-2% of all pancreatic neoplasms. PNETs are a heterogeneous group with varying clinical presentation, tumor biology and prognosis. This article reviews the current diagnostic strategy and treatment armamentarium for

Neuroendocrine tumors of the larynx
Head & Neck, 1991AbstractA review of the international literature has revealed 68 paragangliomas, 42 large cell, and 74 small cell tumors of the larynx. Paragangliomas are usually benign, although malignant cases have been reported. Large cell tumors are malignancies associated with a high incidence of early cervical metastasis. Small cell tumors are aggressive cancers

Neuroendocrine Tumors of the Pancreas
Current Treatment Options in Gastroenterology, 2004Neuroendocrine tumors (NETs) are rare tumors of the endocrine pancreas that require a high degree of suspicion for timely diagnosis. Diagnosis is often delayed due to the nonspecific and intermittent presentation of symptoms. As many as 45% to 55% of tumors are nonfunctional and are typically diagnosed secondary to mass effect related symptoms or found

Epidemiology of Neuroendocrine Tumors
2015Formerly named carcinoids, neuroendocrine tumors originate from diffuse endocrine cells, can involve any part of the gastrointestinal tract, endocrine pancreas and bronchopulmonary (BP) tree, and have a wide range of malignant potential. This chapter summarizes the data available on the epidemiology of neuroendocrine neoplasia (NEN) from around the ...

Virotherapy of Neuroendocrine Tumors
Neuroendocrinology, 2012Most patients with small intestinal neuroendocrine tumors (SI-NETs), also referred to as midgut carcinoids, present with systemic disease at the time of diagnosis with metastases primarily found in regional lymph nodes and the liver. Curative treatment is not available for these patients and there is a need for novel and specific therapies.
