About

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase II trial to study the effectiveness of bortezomib in treating patients who have diffuse large B-cell lymphoma that is refractory to previous chemotherapy.

Full description

OBJECTIVES: Determine the overall response rate in patients with chemotherapy-refractory diffuse large B-cell lymphoma treated with bortezomib. Determine the safety and tolerability of this drug in these patients. Determine the time to disease progression in patients treated with this drug. Determine the possible mechanism of resistance to this drug in these patients. OUTLINE: This is an open-label, multicenter study. Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity. Patients are followed at 20 days and then every 3 months thereafter. PROJECTED ACCRUAL: A total of 22-40 patients will be accrued for this study.
