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 tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining rituximab with combination chemotherapy may kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of combining rituximab with combination chemotherapy in treating patients who have previously untreated non-Hodgkin's lymphoma.

Full description

OBJECTIVES:

• Determine the response rate, progression-free survival, and overall survival of patients with previously untreated aggressive CD20+ B-cell diffuse large cell or immunoblastic large cell lymphoma treated with rituximab, doxorubicin, etoposide, vincristine, prednisone, and cyclophosphamide.
• Determine the toxic effects of this regimen in these patients.
• Correlate tumor proliferation rate (MIB-1), bcl-2 expression, and p53 overexpression with complete response rate, progression-free survival, and overall survival in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive rituximab IV on day 1; doxorubicin IV continuously, etoposide IV continuously, and vincristine IV continuously on days 1-4; oral prednisone twice daily on days 1-5; and cyclophosphamide IV on day 5. Patients also receive filgrastim (G-CSF) subcutaneously beginning on day 6 and continuing until blood counts recover. Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity. After 4 courses, patients with complete or partial response receive 2 additional courses.

Patients are followed every 3 months for 2 years and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 25-50 patients will be accrued for this study within 1 year.

Enrollment: 78 patients

Sex: All

Volunteers: No Healthy Volunteers
