Perioperative Imatinib Mesylate in Treating Patients With Locally Advanced Gastrointestinal Stromal Tumor

Summary

Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Perioperative imatinib mesylate may shrink the tumor and may reduce the chance of relapse after surgery. This phase II trial is studying the effectiveness of perioperative imatinib mesylate in treating patients with locally advanced gastrointestinal stromal tumor.
