General Information About Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumor is a disease in which abnormal cells form in the tissues of the gastrointestinal tract. The gastrointestinal (GI) tract is part of the body's digestive system. It helps to digest food and takes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from food so they can be used by the body. The GI tract is made up of the following organs: Stomach. Small intestine. Large intestine (colon). Gastrointestinal stromal tumors (GISTs)...

Chemoprevention is the use of substances to lower the risk of cancer, or keep it from recurring. The substances may be natural or made in the laboratory. Some chemopreventive agents are tested in people who are at high risk for a certain type of cancer. The risk may be because of a precancerous condition, family history, or lifestyle factors.

Some chemoprevention studies have shown good results. For example, selective estrogen receptor modulators (SERMS) such as tamoxifen or raloxifene have been shown to reduce the risk of breast cancer in women at high risk. Finasteride and dutasteride have been shown to reduce the risk of prostate cancer.

See the following PDQ summaries for more information:

New ways to prevent cancer are being studied in clinical trials.

Chemoprevention agents that are being studied in clinical trials include COX-2 inhibitors. They are being studied for the prevention of colorectal and breast cancer. Aspirin is being studied for the prevention of colorectal cancer.

See the following PDQ summaries for more information:

Clinical trials are taking place in many parts of the country. Check NCI's PDQ Cancer Clinical Trials Registry for cancer prevention trials that are now accepting patients.

See the NCI Web site for more information about cancer prevention.
