Do you need chemo for a GIST?

Does Chemo work for GIST?

While surgery is usually the main type of treatment for a GIST, chemotherapy can also be incorporated into a patient’s treatment plan. Chemotherapy drugs work by attacking rapidly growing cells within the body; this can help shrink gastrointestinal stromal tumors.

Should a GIST tumor be removed?

If the tumor is small, it often can be removed along with a small area of normal tissue around it. This is done through a cut (incision) in the skin. Unlike many other cancers, GISTs almost never spread to the lymph nodes, so removing nearby lymph nodes is usually not needed.

What percentage of GIST tumors are cancerous?

Localized (cancer remains in the organ where it started): 93 percent.

Can you be cured of GIST?

For people with a localized GIST, surgery is the standard treatment and should be performed whenever possible. If the GIST cannot be completely removed by surgery, such as if it has spread somewhere else, it often cannot be cured. However, surgery may be considered if there is only a limited amount of disease.

How long do you take Gleevec for GIST?

An initial dose of 400 mg daily is indicated, however patients with exon 9 mutations may benefit from dose escalation. Optimal duration of therapy is unknown but generally imatinib should be continued for 6–9 months, after which additional tumor shrinkage is usually minor.

How serious is a GIST?

Small GIST s may cause no symptoms, and they may grow so slowly that they have no serious effects. People with larger GIST s usually seek medical attention when they vomit blood or pass blood in their stool due to rapid bleeding from the tumor.

How rare is a GIST tumor?

GISTs are rare, making up less than 1% of all gastrointestinal tumors. Each year, approximately 4,000 to 6,000 adults in the United States will be diagnosed with a GIST. About 60% of GISTs begin in the stomach, and around 35% develop in the small intestine.

Is GIST always malignant?

GISTs are rare tumors that can start anywhere in the intestinal tract. Some GISTs may cause bleeding, stomach pain or bloating. Other GISTs cause no symptoms and are detected accidentally during a procedure for another condition. Some GISTs are cancerous, but with treatment, the outlook is promising.

Do GISTs always come back?

Tumors that are small and are not growing quickly typically have a low risk of coming back, so often no further treatment is needed. The risk of a GIST coming back after surgery is higher if: The tumor is larger.

Where do GIST tumors come from?

A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine. This type of tumor is thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells.
