text: Treatment for<unk>  may consists of chemotherapy, radiation therapy and surgery and treatments depends on staging classification and risk stratification.<unk>  chemotherapy depends on patient's risk groups. Vincristine, actinomycin D,and cyclophosphamide are the fundamental chemotherapy standard based on Children's Oncology Group. Ifosfamide, vincristine, and actinomycin D are the fundamental chemotherapy standard base on European Soft tissue Sarcoma Group. Patients's response to chemotherapy is classified to five groups as complete response, good response, poor response, objective response, and progressive disease. Radiation therapy may be used as local therapy and is usually initiated after 4 chemotherapy cycles. The only exception for starting radiotherapy from the first day is vision loss and spinal cord compression. Radiotherapy dosage is based on completeness of tumor resection before chemotherapy and completeness of a delayed primary tumor excision after adjuvant chemotherapy.
