RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine together with bortezomib may kill more cancer cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of bortezomib when given together with gemcitabine and to see how well they work in treating patients with relapsed or refractory B-cell or T-cell non-Hodgkin's lymphoma.
- Determine the response rate (complete and partial remission) in patients with relapsed or refractory aggressive B- or T-cell non-Hodgkin's lymphoma treated with gemcitabine hydrochloride and bortezomib.
- Determine the maximum tolerated dose of bortezomib when administered with gemcitabine hydrochloride in these patients.
- Determine the time to treatment failure, duration of response, and overall survival of patients treated with this regimen.
- Determine the safety and tolerability of this regimen in these patients.
OUTLINE: This is a phase I, dose-escalation study of bortezomib followed by a phase II, open-label study.
- Phase I: Patients receive gemcitabine hydrochloride IV over 30 minutes and bortezomib IV over 3-5 seconds on days 1 and 8. Treatment repeats every 21 days for up to 9 courses in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of bortezomib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 3 of 6 patients experience dose-limiting toxicity (DLT) OR the dose that at which 2 of 6 patients experience DLT.
- Phase II: Patients receive gemcitabine hydrochloride and bortezomib as in phase I at the MTD.
After completion of study therapy, patients are followed periodically for 3 years.
PROJECTED ACCRUAL: A total of 37 patients will be accrued for this study.

Phase 2 trial of bortezomib in combination with rituximab plus hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with bortezomib, rituximab, methotrexate, and cytarabine for untreated mantle cell lymphoma.
Although the outcomes of patients with mantle cell lymphoma (MCL) have improved, there is still no cure. Bortezomib has a 33% response rate in relapsed/refractory MCL and has shown additive and/or syn...

A pyrazine and boronic acid derivative that functions as a reversible PROTEASOME INHIBITOR. It is used as an ANTINEOPLASTIC AGENT in the treatment of MULTIPLE MYELOMA and MANTLE CELL LYMPHOMA.
A nitrogen mustard compound that functions as an ALKYLATING ANTINEOPLASTIC AGENT and is used in the treatment of CHRONIC LYMPHOCYTIC LEUKEMIA and NON-HODGKIN'S LYMPHOMA.
A leukemia/lymphoma found predominately in children and young adults and characterized LYMPHADENOPATHY and THYMUS GLAND involvement. It most frequently presents as a lymphoma, but a leukemic progression in the bone marrow is common.
B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
