Need Carcinoid Tumors
Carcinoid refers to neuroendocrine tumors originating in gastrointestinal (GI) tract, lungs and appendix. They are usually indolent developing over many years. Aggressive, fast-growing forms such SCLC known as Oat Cell Ca of lung represents neuroendocrine carcinoma that exhibits rapid growth and early spread to distant sites. They are sensitive ...Read more
Neuroendocrine tumor: It is a relatively benign type of tumor that can secrete a variety of hormones, most notably serotonin. They are most commonly found in the gut or the lungs. They do not come from the lining of the lungs or the gut (as adenocarcinomata do). They come from a different line of cells. Carcinoid syndrome occurs when large amounts of serotonin get into the bloodstream, assoc with flushing and diarrhea. ...Read more
Not always!: The most common place to have a carcinoid is the appendix. When the tumor is there, and most of the other common locations which are in the intestinal tract, you don't feel anything because the liver removes the hormones the tumors produce. Only when the tumors are large, outside the intestinal tract, or metastatic do the symptoms occur. They can get very bad then. ...Read more
Location? extent?: Tumors of neuroendocrine origin; can be hard to localize; can be in appendix, rectum, bowel, stomach/duodenum, ovaries, bronchi (breathing tubes), elsewhere. "low" malignant potential, but can be aggressive, spread; can cause abd pain, ;"syndrome" with flushing, wheezing, murmurs, etc. Small ones can be cured by surgical removal; may need chemo, embolization, or octreotide rx for symptom control. ...Read moreSee 2 more doctor answers
Not known: Carcinoid tumors of the bowel are neuroendocrine tumors that have a high propensity of spreading to the liver and producing the carcinoid syndrome. The lesions arise anywhere in the bowel and respond to the same chemo used for small cell neuroendocrine of lung. They even arise in organs like pancreas, like Jobs had but are not pancreatic tumors.. Cause is not known but possibly viral in etiology ...Read more

Carcinoid tumor: Carcinoid tumors can be found in several places in the intestines. They do not cause symptoms unless the liver is affected. Carcinoid syndrome can be associated with flushing, increase in blood pressure, irregular heart beat, etc. If a carcinoid is located with a bowel lumen it can cause blockage. Carcinoids can spread directly to other areas. Usually not by blood stream. ...Read moreSee 1 more doctor answer
Long yet variable: Carcinoid tumors are slow growing cancers which can exist in the body for 10-20+ years without causing a major threat to life. But this depends on where they are located and if they have spread to the liver or not. Liver spread does lead to increasing problems and some fatal outcomes, typically after 5 to 10+ years. It has a highly variable prognosis. ...Read more
Can Abilify (aripiprazole) cause false negative test results when being tested for carcinoid tumors?
Apparently not: There are a variety of drugs that can affect the 5-hiaa test.

What is the risk of having multifocal carcinoid tumors in stomach and duodenal type-1 and what is the latest news about available treatments?

Reduction of gastrin levels felt to be helpful. ...Read moreSee 1 more doctor answer

Can carcinoid tumors cause carcinoid crises with clonoscopy&endoscopy anesthesia?I have elavated serotonin;constipation,heat in neck&head;night diahri
Unlikely: Carcinoid crisis is a possible complication in someone who has a carcinoid tumor. You don't say if you have been diagnosed with Carcinoid. General anesthesia can trigger carcinoid crisis in such patients, but the "conscious sedation" used for most diagnostic procedures such as colonoscopy or endoscopy would be unlikely to do so. Have you done a 24 hr urine 5-HIAA? ...Read more
Slower growing: Carcinoid tumors can occur throughout the intestine and may act in a malignant fashion and spread to lymph nodes and other organs. They tend to grow more slowly that more common (adenocarcinomas) cancers in the intestinal tract. They can sometimes be cured with surgery and survival can be long term even after spread due to their nature of sometimes growing very slowly. ...Read moreSee 2 more doctor answers
