Official Title: Protocol For The Treatment Of Relapsed And Refractory Wilms Tumour And Clear Cell Sarcoma Of The Kidney (CCSK)

Brief Summary:

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.

PURPOSE: This phase II trial is studying how well chemotherapy followed by surgery and radiation therapy with or without stem cell transplant work in treating patients with relapsed or refractory Wilms' tumor or clear cell sarcoma of the kidney.


Detailed Summary:

OBJECTIVES:

  • Determine survival rates of patients with relapsed or refractory Wilms' tumor or clear cell sarcoma of the kidney treated with chemotherapy followed by surgical resection and adjuvant radiotherapy with or without autologous stem cell rescue.
  • Determine the efficacy and toxicity of these regimens in these patients.
  • Determine prognostic variables in patients treated with these regimens.

OUTLINE: Patients are assigned to one of three treatment regimens.

  • Regimen A (patients with initial stage I tumors previously treated with vincristine with or without dactinomycin with relapse at least 6 months after diagnosis): Patients receive vincristine IV once weekly on weeks 1-10 and then every 3 weeks during weeks 11-52, dactinomycin IV every 3 weeks during weeks 1-52, and doxorubicin IV over 6 hours every 3 weeks during weeks 1-34 (weeks 1-28 if pulmonary radiotherapy is planned). Patients undergo surgical resection and radiotherapy after 6 weeks of therapy.
  • Regimen B (patients with initial stage II tumors previously treated with vincristine and dactinomycin with relapse at least 6 months after diagnosis): Patients receive cyclophosphamide IV twice daily on days 1-2 and 22-23, etoposide IV over 1 hour on days 1-3, and doxorubicin IV over 6 hours on days 22 and 23. Treatment repeats every 42 days for a total of 4 courses. Patients undergo surgical resection and radiotherapy after 2 courses of chemotherapy. Patients not achieving complete response after 4 courses of chemotherapy undergo autologous bone marrow transplantation as in regimen C.
