Summary
Brief summary
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the
enzymes needed for cell growth. Giving imatinib mesylate after surgery may kill any remaining
tumor cells. It is not yet known whether imatinib mesylate is more effective than observation
only in treating gastrointestinal stromal tumor.

PURPOSE: This randomized phase III trial is studying imatinib mesylate to see how well it
works compared to observation only in treating patients who have undergone surgery for
localized gastrointestinal stromal tumor.
