Study Arms:
- Chemotherapy and local control by radiotherapy and surgery (Type: EXPERIMENTAL): Patients receive doxorubicin hydrochloride and ifosfamide (IA) chemotherapy. Treatment repeats every 21 days for 2 courses in the absence of unacceptable toxicity. Patients then receive etoposide and ifosfamide (IE) chemotherapy. Treatment repeats every 21 days for 2 courses in the absence of disease progression or unacceptable toxicity. Patients also receive filgrastim (G-CSF) subcutaneously (SC) after each chemotherapy course. After recovery from chemotherapy, patients undergo radiotherapy and receive 2 more courses of IE during radiotherapy followed by 2 more courses of IA after completion of radiotherapy. Some patients may then undergo surgery.
- Chemotherapy and local control by surgery (Type: EXPERIMENTAL): Patients receive 2 courses of IA followed by 2 courses of IE as above. After recovery from chemotherapy, patients undergo surgery. After recovery from surgery, patients receive 2 more courses of IA followed by 2 more courses of IE in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
