Phase III Study of Ifosfamide and Doxorubicin Hydrochloride, Radiotherapy, and/or Surgery in Patients With Localized Non-Rhabdomyosarcoma Soft Tissue Sarcoma

- Determine survival rates (event-free survival and overall survival [OS]) and the pattern of treatment failure in patients with synovial sarcoma or adult-type soft tissue sarcoma treated with ifosfamide and doxorubicin hydrochloride, radiotherapy, and/or surgery. - Determine the role of ifosfamide and doxorubicin hydrochloride in improving the response rate in patients with unresectable synovial sarcoma or adult-type soft tissue sarcoma.
