OUTLINE: Patients receive carboplatin IV over 1 hour on days 0, 21, and 63; cyclophosphamide IV over 1 hour on days 21 and 42; doxorubicin IV over 15-60 minutes on days 21 and 63; and etoposide IV over 2 hours on days 0-2, 42-44, and 63-65. Patients under 60 days of age also receive filgrastim (G-CSF) or sargramostim (GM-CSF) subcutaneously beginning 24 hours after the last chemotherapy administration and continuing until blood counts recover. Patients with favorable biology who do not achieve complete remission then undergo surgery to remove or debulk residual disease on day 84 or when blood counts recover. Patients with favorable biology who achieve partial response and surgery to the primary site is not deemed in the best interest of the patient may receive additional chemotherapy (as below) and delay surgery to the primary site after completion of chemotherapy.
