Gastrointestinal Stromal Tumors Treatment (PDQ®)

Treatment Options for Gastrointestinal Stromal Tumors

Resectable Gastrointestinal Stromal Tumors

Resectable gastrointestinal stromal tumors (GISTs) can be completely or almost completely removed by surgery. Treatment may include the following:

Unresectable Gastrointestinal Stromal Tumors

Unresectable GISTs cannot be completely removed by surgery because they are too large or in a place where there would be too much damage to nearby organs if the tumor is removed. Treatment is usually a clinical trial of targeted therapy with imatinib mesylate to shrink the tumor, followed by surgery to remove as much of the tumor as possible.

Metastatic and Recurrent Gastrointestinal Stromal Tumors

Treatment of GISTs that are metastatic (spread to other parts of the body) or recurrent (came back after treatment) may include the following:

Refractory Gastrointestinal Stromal Tumors

Many GISTs treated with a tyrosine kinase inhibitor (TKI) become refractory (stop responding) to the drug after a while. Treatment is usually a clinical trial with a different TKI or a clinical trial of a new drug.

Treatment Options in Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with gastrointestinal stromal tumor. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI Web site.
