Frequent question: Where are most carcinoid tumors located?

Where do carcinoid tumors metastasize?

The most common sites of metastasis from midgut carcinoid tumors are mesenteric lymph nodes and the liver. Metastases to the lung, peritoneum, bone, and pancreas are less common. Rare sites of metastasis include soft tissues (,17), the breast (,18), and the orbit (,19).

Are most carcinoid tumors benign?

Carcinoid tumors are noncancerous (benign) or cancerous (malignant) growths that sometimes produce excessive amounts of hormone-like substances (such as serotonin), resulting in the carcinoid syndrome.

What is the life expectancy of someone with carcinoid cancer?

Overall, people with carcinoid tumours have a good life expectancy compared to many other cancers, with around 70-80% surviving at least five years from diagnosis. Many people remain relatively well and lead active lives, with only occasional symptoms.

Do carcinoid tumors need to be removed?

Because most carcinoid tumors grow slowly and some do not cause any symptoms, completely removing all metastatic carcinoid tumors may not always be needed. But in some patients, surgery to remove all visible cancer is the best option.

What foods to avoid if you have carcinoid tumors?

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. There are other changes you can make to your diet to better manage symptoms.

Can carcinoid tumors cause weight gain?

Some carcinoid tumors produce ACTH (adrenocorticotropic hormone), a substance that causes the adrenal glands to make too much cortisol (a steroid). This can cause Cushing syndrome, with symptoms of: Weight gain.

Can carcinoid tumors be seen on CT scan?

A CT scan is most often used to look at the chest and/or belly (abdomen) to see if GI neuroendocrine (carcinoid) tumors have spread to nearby lymph nodes or other organs such as the liver. It can also be used to guide a biopsy needle into an area of concern..

Are carcinoid tumors aggressive?

Sporadic carcinoid tumors may be aggressive, with a high incidence of metastases and a 5-year survival rate of less than 75% [48].

Will an MRI show carcinoid tumors?

MRI is able to demonstrate findings in carcinoid tumors, including the primary tumor, mesenteric metastases, and liver metastases. Liver metastases are commonly hypervascular and may be demonstrable only on immediate postgadolinium images.

Can a colonoscopy detect carcinoid tumors?

Passing a scope through your rectum (colonoscopy) can help diagnose rectal carcinoid tumors. To see inside your small intestine, your doctor may recommend a test using a pill-sized camera that you swallow (capsule endoscopy).
