   Combination Chemotherapy With or Without Peripheral Stem Cell Transplantation, Radiation Therapy, and/or Surgery in Treating Patients With Ewing's Sarcoma

   Location:

   Rochester, MN

   Trial status:

   Open for Enrollment

   Why is this study being done?

   OBJECTIVES: Primary - Compare the event-free and overall survival of patients with tumor of the Ewing's family treated with standard induction chemotherapy comprising vincristine, dactinomycin, ifosfamide and etoposide (VIDE) followed by consolidation chemotherapy comprising vincristine, dactinomycin, and ifosfamide versus high-dose busulfan and melphalan (Bu-Mel) followed by autologous peripheral blood stem cell (PBSC) transplantation with or without radiotherapy and/or surgery. Secondary - Determine the prognostic significance of EWS-Flil transcript in these patients. - Determine the frequency and prognostic value of minimal disease in bone marrow and PBSC, as determined by the presence or absence of EWS-Flil transcript, in these patients. - Determine the feasibility and toxicity of VIDE induction chemotherapy in these patients. - Determine the response of these patients to VIDE induction chemotherapy. - Determine the feasibility and toxicity of VAI consolodation chemotherapy in these patients. - Determine the feasibility and toxicity of Bu-Mel consolodation chemotherapy in these patients. - Determine event-free survival and overall survival of patients treated with these regimens by prognostic group analysis. OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age and local treatment of the primary tumor (yes vs no). Patients receive induction chemotherapy comprising vincristine IV on day 1 and ifosfamide IV over 3 hours, doxorubicin IV over 4 hours, and etoposide IV over 1 hour on days 1-3 (VIDE). Treatment repeats every 21 days for 4 courses in the absence of unacceptable toxicity. Peripheral blood stem cells (PBSC) are collected after course 3 and/or 4. Patients are evaluated after course 4. Patients in need of early radiotherapy due to an axial tumor or patients who require radiotherapy to the brain and/or spinal cord (at any time during study) are assigned to group 1. Patients not needing early radiotherapy are assigned to group 2. - Group 1: Patients receive 2 additional courses of VIDE induction chemotherapy (courses 5 and 6). Patients requiring radiotherapy to the axial tumor also undergo concurrent radiotherapy 5 days a week. Some patients may then undergo surgical resection of the tumor. All patients will then receive vincristine IV on day 1 and dactinomycin IV and ifosfamide IV over 3 hours on days 1 and 2 (VAI). Treatment repeats every 21 days for 8 courses (courses 7-14). Patients requiring radiotherapy to the brain and/or spinal cord also undergo concurrent radiotherapy. - Group 2: Patients undergo 2 additional courses of VIDE induction chemotherapy (courses 5 and 6). Some patients may then undergo surgical resection of the tumor. All patients receive VAI chemotherapy as in group 1 for 1 course. Patients are randomized to 1 of 2 consolidation therapy arms. - Arm I: Patients receive 7 additional courses of VAI chemotherapy (courses 8-14). Patients with unresectable, partially resected, or inadequately resected disease undergo concurrent whole-lung radiotherapy for 6-12 days. - Arm II: Patients receive high-dose chemotherapy comprising oral busulfan every 6 hours on days -6 to -3 and melphalan IV over 30 minutes on day -2. Patients receive autologous PBSC IV on day 0. Patients with unresectable, partially resected, or inadequately resected disease undergo concurrent radiotherapy 5 days a week for at least 5 weeks. Patients are followed every 3 months for 4 years, every 6 months for 1 year, and then periodically thereafter. Peer Reviewed and Funded or Endorsed by Cancer Research UK PROJECTED ACCRUAL: Approximately 1,200 patients will be accrued for this study within approximately 7 years.

   Collecting and Storing Biological Samples From Patients With Ewing Sarcoma

   Location:

   Rochester, MN

   Trial status:

   Open for Enrollment

   Why is this study being done?

   OBJECTIVES: - Collect biological specimens, including associated demographic and clinical data, from patients with Ewing sarcoma. - Provide a repository for long-term storage of Ewing sarcoma-related biological materials. - Make collected specimens available to qualified researchers to understand the biology of Ewing sarcoma and correlate these results with demographic and clinical data. OUTLINE: This is a multicenter study. Patients undergo collection of tumor specimens, bone marrow, and peripheral blood at diagnosis. Associated demographic and clinical data are collected and archived. Patients who are not enrolled on a therapeutic clinical trial are followed annually. PROJECTED ACCRUAL: Not specified.

   Combination Chemotherapy in Treating Patients With Non-Metastatic Extracranial Ewing Sarcoma

   Location:

   Rochester, MN

   Trial status:

   Open for Enrollment

   Why is this study being done?

   OBJECTIVES: Primary - Test the effect of the combination of vincristine, cyclophosphamide, and topotecan (VTC) added to the standard 5-drug chemotherapy interval-compressed backbone on event-free survival (EFS) and overall survival of children and young adults with Ewing sarcoma. Secondary - Evaluate initial volumetric tumor size as a prognostic factor for EFS in patients with localized Ewing tumors. - Evaluate histologic response as a prognostic factor for EFS in patients with localized Ewing tumors. - Continue evaluation of biologic markers both as related to prognosis and as eventual therapeutic targets via encouraging concurrent enrollment on a Ewing sarcoma specimen-collection study. - Evaluate imaging response by FDG-positron emission tomography (PET) as a prognostic factor for EFS. - Evaluate the effects of the type of local therapy on EFS and overall survival. - Evaluate the effect of local surgical margins in conjunction with histologic response on EFS in patients with localized Ewing tumors. - Evaluate the effect of local therapy modality (surgery, radiotherapy, or a combination) as well as the type of surgical reconstruction on musculoskeletal complications. OUTLINE: This is a multicenter study. Patients are stratified according to age (≤ 17 years vs ≥ 18 years) and primary tumor site (pelvic vs non-pelvic vs extra-osseous). Patients are randomized to 1 of 2 treatment arms. - Arm I: - Induction therapy: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 5, 6, 9, and 10; doxorubicin hydrochloride IV on days 1 and 2 and cyclophosphamide IV over 30-60 minutes on day 1 in weeks 1, 5, and 9; and ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 in weeks 3, 7, and 11. - Consolidation therapy: Patients receive vincristine sulfate on day 1 in weeks 1, 2, 7, 8, 9, 10, 13, 14, 17, 18, 21, and 22; doxorubicin hydrochloride IV on days 1 and 2 in weeks 1 and 9; cyclophosphamide IV over 30-60 minutes on day 1 in weeks 1, 7, 9, 13, 17, and 21; and ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 in weeks 3, 5, 11, 15, and 19. - Arm II: - Induction therapy: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 5, 6, 9, 10, 11 and 12; topotecan hydrochloride IV over 30 minutes on days 1-5 in weeks 1 and 9; cyclophosphamide IV over 15-60 minutes on days 1-5 in weeks 1 and 9, and on day 1 of weeks 5 and 11; ifosfamide and etoposide as in arm I; and doxorubicin hydrochloride IV on days 1 and 2 in weeks 5 and 11. - Consolidation therapy: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 7-10, 13-16, 19, and 20; topotecan hydrochloride IV over 30 minutes on days 1-5 in weeks 1, 7, and 15; cyclophosphamide IV over 15-60 minutes on days 1-5 in weeks 1, 7, and 15, and on day 1 in weeks 9, 13, and 19; ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 in weeks 3, 5, 11, 17, and 21; and doxorubicin hydrochloride IV on days 1 and 2 in weeks 9, 13, and 19. Patients with responsive or stable disease undergo may undergo surgery alone in week 13 if lesion can be complete resected with negative margins and with reasonable functional result. Patients with unresectable lesions or inadequate margins after surgery receive radiotherapy during weeks 1-7. Patients with bulky lesions in surgically difficult sites such as the spine, skull, and periacetabular pelvis, patients with a poor response to induction chemotherapy, or those patients in whom surgery would result in unacceptable functional results may undergo radiotherapy alone in weeks 1-7 of consolidation therapy, and surgery should be performed after completion of consolidation chemotherapy. Patients with microscopic residual disease after planned pre-operative radiotherapy receive additional radiotherapy. After completion of study therapy, patients are followed up periodically for 10 years.
