简要总结
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known which therapy regimen is most effective for treating patients with kidney tumors.
PURPOSE: Phase III trial to compare the effectiveness of chemotherapy with or without radiation therapy, surgery, and/or peripheral stem cell or bone marrow transplantation in treating young patients with kidney tumors.
详细描述
OBJECTIVES:
- Determine the 2-year second-event-free survival after vincristine (VCR) and dactinomycin (DACT) with or without doxorubicin (DOX), depending on the site of relapse and presence of microscopic residual disease, in children with relapsed Wilm's tumor previously treated with nephrectomy alone as initial therapy.
- Determine whether the 2-year second-event-free survival after intensive doxorubicin, etoposide (VP-16), cyclophosphamide (CTX), and carboplatin (CBDCA) plus radiotherapy to residual disease is at least 40% higher in patients with relapsed Wilm's tumor previously treated with Regimen EE-4A as initial therapy and without loss of heterozygosity for chromosomes 16q and 1p and increased DNA content in tumor cells than for similarly treated patients with loss of heterozygosity for chromosome 16q or 1p or increased DNA content in tumor cells.
- Determine whether the 4-year post-relapse survival after intensive VP-16, CTX, and CBDCA is at least 40% higher in patients with relapsed Wilm's tumor previously treated with Regimen DD-4A as initial therapy and without loss of heterozygosity for chromosomes 16q and 1p and increased DNA content in tumor cells than for similarly treated patients with loss of heterozygosity for chromosome 16q or 1p or increased DNA content in tumor cells.
- Determine whether the rates of complete and partial response exceed 20% in patients with relapsed clear cell sarcoma of the kidney or diffuse anaplastic Wilms' tumor treated with CBDCA combined with VP-16.
OUTLINE: This is a multicenter study.
Patients are assigned to a treatment group based on initial therapy and histology. Patients under age 2 at diagnosis who were previously treated with nephrectomy as initial therapy for stage I favorable histology Wilms' tumor weighing less than 550 grams are assigned to group A. Patients who received Regimen EE-4A as initial therapy for Wilms' tumor are assigned to group B. Patients who received Regimen DD-4A as initial therapy for Wilms' tumor are assigned to group C. Patients with clear cell sarcoma of the kidney or diffuse anaplastic Wilms' tumor are assigned to group D.
