What does GEP NET stand for?
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs), also known as carcinoids and islet cell tumors, are tumors derived from neuroendocrine cells that can occur anywhere along the gastrointestinal tract and comprise a heterogeneous family of neoplasms with a wide and complex spectrum of clinical behavior.
Who treats GEP NET?
During the next stages of treatment, the optimal management of a GEP-NET patient is provided mainly by endocrinologists, nuclear physicians, oncologists, interventional radiologists, gastroenterologists, specialized nurses, geneticists, and cardiologists, among others .
Are neuroendocrine tumors genetic?
Although neuroendocrine tumors are in some cases associated with inherited genetic syndromes, such syndromes are rare. The majority of neuroendocrine tumors are thought to be sporadic. We performed a genome-wide association study (GWAS) to identify potential genetic risk factors for sporadic neuroendocrine tumors.
What does elevated chromogranin A mean?
An increased Chromogranin A level in a person with symptoms may indicate the presence of a tumor, but it is not specific for the type of tumor or its location. In order to diagnose the condition, the tumor itself must be located, biopsied, and examined by a pathologist.
Where is neuroendocrine tumor?
Neuroendocrine tumors are rare and can occur anywhere in the body. Most neuroendocrine tumors occur in the lungs, appendix, small intestine, rectum and pancreas.
Who specializes in neuroendocrine tumors?
Specialists may include:
- Medical oncologists.
- Transplant specialists.
- Nuclear medicine specialists.
Who specializes in carcinoid tumors?
Who treats GI carcinoid tumors?
- A surgical oncologist: a doctor who treats cancer with surgery.
- A medical oncologist: a doctor who treats cancer with medicines.
- A radiation oncologist: a doctor who treats cancer with radiation therapy.
Can stress cause neuroendocrine tumors?
The neuroendocrine mechanisms of chronic stress. Chronic stress produces stress hormones during the activation of the neuroendocrine system (hypothalamus-pituitary-adrenal axis) and the sympathetic nervous system, which can promote tumor development and regulate the tumor microenvironment.
What foods should be avoided with carcinoid syndrome?
Avoid foods that contain high amounts of mines, nitrogen-containing organic compounds, as they can trigger the release of serotonin and other hormones. These foods include fatty meats, smoked or salted fish, aged cheeses, and even chocolate.
