Treatment Option Overview
Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working.
Hepatic arterial occlusion or chemoembolization
Hepatic arterial occlusion uses drugs, small particles, or other agents to block or reduce the flow of blood to the liver through the hepatic artery (the major blood vessel that carries blood to the liver). This is done to kill cancer cells growing in the liver. The tumor is prevented from getting the oxygen and nutrients it needs to grow. The liver continues to receive blood from the hepatic portal vein, which carries blood from the stomach and intestine.
Chemotherapy delivered during hepatic arterial occlusion is called chemoembolization. The anticancer drug is injected into the hepatic artery through a catheter (thin tube). The drug is mixed with the substance that blocks the artery and cuts off blood flow to the tumor. Most of the anticancer drug is trapped near the tumor and only a small amount of the drug reaches other parts of the body.
The blockage may be temporary or permanent, depending on the substance used to block the artery.
Supportive care is given to lessen the problems caused by the disease or its treatment. Supportive care for islet cell cancer may include treatment for the following:
- Stomach ulcers may be treated with drug therapy such as:
- Diarrhea may be treated with:
- Low blood sugar may be treated by having small, frequent meals or with drug therapy to maintain a normal blood sugar level.
- High blood sugar may be treated with drugs taken by mouth or insulin by injection.
New types of treatment are being tested in clinical trials.
Information about clinical trials is available from the NCI Web site.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
