About
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy, total-body irradiation, and peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving chemotherapy with rituximab followed by combination chemotherapy with or without rituximab, total-body irradiation, and peripheral stem cell transplant works in treating patients with lymphoma.
Full description
OUTLINE: Patients are stratified according to risk (low-intermediate vs high-intermediate or high).
Patients receive induction chemotherapy comprising cyclophosphamide IV, doxorubicin IV over 15 minutes, and vincristine IV over 1-2 minutes on day 1; oral prednisone once daily on days 1-5; and filgrastim (G-CSF) subcutaneously (SC) once daily on days 7-11 or PEG-filgrastim once at least 24 hours after infusion. Patients also receive rituximab IV 2-3 days apart for a total of 2 doses during the week prior to the first course of chemotherapy and on day 1 of courses 2-4 of chemotherapy. Treatment repeats every 14 days for a total of 4 courses in the absence of disease progression or unacceptable toxicity.
After the completion of induction chemotherapy, patients undergo CT scan and positron emission tomography (PET) scanning. If the PET scan is positive in one or more nodal sites, a repeat biopsy is performed. Patients with a negative PET scan OR a negative repeat biopsy (including no evidence of lymphoma on repeat bone marrow biopsy) are assigned to receive regimen A for consolidation therapy. Patients with a positive repeat biopsy are assigned to receive regimen B for consolidation therapy.
Patients who receive consolidation therapy on regimen A are followed at 4-6 weeks after chemotherapy and patients who receive consolidation therapy on regimen B are followed at 90-120 days after transplantation. All patients are followed closely for 5 years and then annually thereafter.
PROJECTED ACCRUAL: A total of 40-98 patients will be accrued for this study within 4 years.
