A Phase III Randomized Trial of Adding Vincristine-topotecan-cyclophosphamide to Standard Chemotherapy in Initial Treatment of Non-metastatic Ewing Sarcoma
This randomized phase III trial studies combination chemotherapy to see how well it works compared to combination chemotherapy with topotecan hydrochloride in treating patients with non-metastatic extracranial Ewing sarcoma. Drugs used in chemotherapy, such as vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide, etoposide, and topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known whether combination chemotherapy is more effective with topotecan hydrochloride in treating Ewing sarcoma.
• Patients with newly diagnosed, biopsy confirmed, extracranial, non-metastatic Ewing sarcoma or primitive neuroectodermal tumor (PNET) of bone or soft tissue are eligible for this study
• Patient eligibility will be based on a diagnosis of Ewing sarcoma or PNET by institutional pathologist
• No prior chemotherapy or radiation therapy is allowed; patients should only have had a biopsy of the primary tumor without an attempt at complete or partial resection; patients will still be eligible if unplanned excision was attempted or accomplished as long as adequate imaging was obtained prior to surgery
