简要总结
RATIONALE: Drugs used in chemotherapy, such as vincristine, doxorubicin, cyclophosphamide, ifosfamide, etoposide, and topotecan, 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. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known which combination chemotherapy regimen is more effective in treating Ewing's sarcoma.
PURPOSE: This randomized phase III trial is studying combination chemotherapy and topotecan to see how well they work compared with combination chemotherapy alone in treating patients with newly diagnosed localized Ewing's sarcoma.
详细描述
OBJECTIVES:
Primary
- Compare the event-free and overall survival of patients with newly diagnosed localized Ewing's sarcoma treated with doxorubicin hydrochloride, cyclophosphamide, vincristine, etoposide, and ifosfamide with vs without topotecan hydrochloride.
- Compare the side effects of these regimens in these patients.
Secondary
- Evaluate initial tumor size as a prognostic factor for event-free survival of these patients.
- Evaluate histological response as a prognostic factor for event-free survival of these patients.
- Continue evaluation of biologic markers both as related to prognosis and as eventual therapeutic targets via encouraging concurrent enrollment on COG-AEWS02B1.
- Evaluate radiologic response by positron emission tomography as a prognostic factor for event-free survival.
