Can carcinoid tumors spread to liver?

The carcinoid is the most common neuroendocrine tumor causing liver metastases, especially when of midgut origin. However, although appendix is the most common location for midgut carcinoids it most unusually gives rise to hepatic spread.

Why does the presence of carcinoid syndrome imply liver metastases?

Manifestations of the carcinoid syndrome usually occur in patients with liver metastases due to production and release of serotonin directly in the blood stream. Classically, the carcinoid syndrome is characterised by episodic flushing, tachycardia, diarrhoea and bronchospasm [8].

How long can you live with metastatic carcinoid?

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 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 carcinoid tumors terminal?

Carcinoid tumors are typically slow-growing. They grow much more slowly than other cancers such as colon, pancreas, liver, and lung cancer. Many small carcinoid tumors produce no symptoms and are not fatal; they are found incidentally at autopsy.

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 is a carcinoid crisis?

Carcinoid crisis is a life-threatening form of carcinoid syndrome that results from the release of an overwhelming amount of biologically active compounds from the tumor that may be triggered by tumor manipulation (biopsy or surgery) or by anesthesia.

What is carcinoid syndrome?

Carcinoid syndrome occurs when a rare cancerous tumor called a carcinoid tumor secretes certain chemicals into your bloodstream, causing a variety of signs and symptoms. A carcinoid tumor, which is a type of neuroendocrine tumor, occurs most often in the gastrointestinal tract or the lungs.

Is metastatic carcinoid tumors curable?

A patient with the carcinoid syndrome and a primary carcinoid tumor which arose in the gastrointestinal tract has metastatic disease and is generally incurable. Nevertheless the clinical course of the disease is often considered slow or indolent.

How long do you live with carcinoid tumors?

They have an overall 5-year survival rate of 78-95% and a 10-year survival rate of 77-90%. If the lung carcinoid tumor has spread to the lymph nodes, five-year survival rates can range from 37 to 80%. Life expectancy is not good for the carcinoid tumor that has spread to other organs of the body.

Can you live with carcinoid?

Carcinoid tumors of the lung generally have better survival outcomes than other forms of lung cancers. They have an overall 5-year survival rate of 78-95% and a 10-year survival rate of 77-90%. If the lung carcinoid tumor has spread to the lymph nodes, five-year survival rates can range from 37 to 80%.

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.

When does carcinoid syndrome occur in the liver?

Carcinoid syndrome occurs when the tumor produces excessive amounts of serotonin in an individual with liver metastases. In patients who have no spread to the liver, the serotonin released by an intestinal tumor will be broken down to an inactive substance; thus, carcinoid syndrome does not occur.

What are the symptoms of metastatic carcinoid syndrome?

Carcinoid syndrome refers to the group of symptoms that result from functional carcinoid tumors. When carcinoid tumors start to spread, or metastasize, they can cause sudden and severe symptoms. These symptoms are the result of an increased release of hormones by the carcinoid tumors.

Can a bronchi tumor cause carcinoid syndrome?

Carcinoid tumors arising in the bronchi may be associated with manifestations of carcinoid syndrome without liver metastases because their biologically active products reach the systemic circulation before passing through the liver and being metabolized.

Where are carcinoid tumors found in the body?

Metastatic carcinoid tumors are a type of malignant (cancerous) neuroendocrine tumor that has already spread to other places throughout the body, such as the liver. Metastatic carcinoid tumors most commonly arise from neuroendocrine cells found in the gastrointestinal (GI) tract, which includes the stomach as well as the small and large
