About

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have metastatic Ewing's sarcoma or primitive neuroectodermal tumor.

Full description

OBJECTIVES:

• Determine the activity of cisplatin and etoposide in terms of response of patients with metastatic Ewing's sarcoma or primitive neuroectodermal tumor.
• Assess the bone marrow and kidney toxicity of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive cisplatin IV over 3 hours on days 1, 8, 15, 29, 36, and 43 and oral etoposide daily on days 1-15 and 29-43 in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 21-45 patients will be accrued for this study within 2 years.

Enrollment: 3 patients

Sex: All

Ages: 15 to 65 years old

Volunteers: No Healthy Volunteers
