Brief Summary:

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth.

PURPOSE: This phase II trial is studying how well imatinib mesylate works in treating patients with recurrent Ewing's family of tumors or desmoplastic small round-cell tumor.

Condition or disease Intervention/treatment Phase
Sarcoma Drug: imatinib mesylate Phase 2

Detailed Description:


  • Determine the effectiveness of imatinib mesylate in patients with recurrent Ewing's family of tumors or desmoplastic small round-cell tumor.
  • Determine the toxic effects of this drug in these patients.
  • Determine the duration of disease-free and overall survival of patients treated with this drug.

OUTLINE: This is an open-label study.

Patients receive oral imatinib mesylate twice daily on days 1-28. Courses repeat every 28 days.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study.
