Treatment of Resectable Gastrointestinal Stromal Tumors

For information about the treatments listed below, see the Treatment Option Overview section.

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

  • Surgery to remove tumors that are 2 centimeters or larger. Laparoscopic surgery may be done if the tumor is 5 cm or smaller. If there are cancer cells remaining at the edges of the area where the tumor was removed, watchful waiting or targeted therapy with imatinib mesylate may follow.
  • A clinical trial of targeted therapy with imatinib mesylate following surgery, to decrease the chance the tumor will recur (come back).
