Brief Summary
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known which dose of imatinib mesylate is more effective in treatin...
Detailed Description
OBJECTIVES: Primary * To compare outcomes of patients with unresectable or metastatic gastrointestinal stromal tumor that expresses KIT (CD117) treated with low-dose imatinib mesylate vs high-dose i...
