A Phase II Study to Evaluate the Role of Weekly Cisplatin With Oral Etoposide in Ewing's Sarcoma and Primitive Neuroectodermal Tumor (PNET) With Bone and/or Bone Marrow Metatstatic Disease
A Phase II Study to Evaluate the Role of Weekly Cisplatin With Oral Etoposide in Ewing's Sarcoma and Primitive Neuroectodermal Tumor (PNET) With Bone and/or Bone Marrow Metatstatic Disease
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.
OBJECTIVES:
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.
DISEASE CHARACTERISTICS:
Histologically confirmed Ewing's family tumor as characterized by the following:
Positive MIC2 on immunohistochemistry OR
Evidence of a chromosomal translocation involving the EWS gene by conventional cytogenetics
Metastases outside the lung or pleura
At least 1 measurable lesion outside of previously irradiated area
No symptomatic or known CNS metastases
