RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known if combining rituximab with cyclophosphamide is more effective than cyclophosphamide alone in stimulating peripheral stem cells for transplantation.
PURPOSE: This randomized phase II trial is studying how well giving cyclophosphamide with or without rituximab followed by chemotherapy and peripheral stem cell transplantation works in treating patients with recurrent non-Hodgkin's lymphoma.
- Compare the effects of mobilization therapy with or without rituximab on hematopoietic stem cells, B and T lymphocytes, and natural killer cells in patients with advanced or recurrent B-cell non-Hodgkin's lymphoma.
- Compare the effects of B-lymphocyte purging using concurrent rituximab and mobilization therapy vs a CD34+ cell enrichment device on hematopoietic stem cells, B and T lymphocytes, and natural killer cells in the peripheral blood stem cell (PBSC) infusates.
- Compare the effect of these purging regimens on tumor cell content of PBSC infusates.
- Compare the effects of these regimens on myeloid and lymphoid engraftment after high-dose chemotherapy and autologous PBSC infusion in these patients.
- Compare post-transplantation infection complications in patients treated with these regimens.
- Compare the response and relapse-free survival of patients treated with these regimens.
OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive mobilization therapy comprising rituximab IV over 2-5 hours on days 1, 8, and 15 and cyclophosphamide IV over 3-6 hours on day 16. Beginning 36-48 hours after the completion of cyclophosphamide, patients receive filgrastim (G-CSF) subcutaneously (SC) daily until blood counts recover. Patients then undergo peripheral blood stem cell (PBSC) collection.
After completion of PBSC collection, patients receive high-dose chemotherapy comprising carmustine IV on days -7 to -3 and etoposide IV and cisplatin IV for 3 days during days -7 to -3. Patients may undergo involved-field radiotherapy to active or previously bulky (more than 5 cm) tumors daily for 7-10 days.
Patients receive unmanipulated PBSCs on day 0. Patients receive G-CSF SC daily beginning 4 hours after completion of PBSC infusion and continuing until neutrophil engraftment.
- Arm II: Patients receive mobilization therapy comprising cyclophosphamide and G-CSF and high-dose chemotherapy comprising carmustine, etoposide, and cisplatin as in arm I. Patients may also undergo involved-field radiotherapy as in arm I. Patients receive CD34 cell-enriched PBSC on day 0 followed by G-CSF as in arm I.
Patients are followed every 3 months.
PROJECTED ACCRUAL: A total of 71 patients will be accrued for this study within 2 years.

Human recombinant G-CSF reduces the duration of neutropenia following HLA-identical allogeneic bone marrow transplantation. However, its use remains controversial due to the risk of increasing the inc...
Toxicity of carmustine and cyclophosphamide can cause pulmonary injury after hematopoietic stem cell transplantation.
Bone remodeling takes place in the bone marrow environment. We investigated if levels of bone turnover markers (BTMs) differ between bone marrow and peripheral blood, if the bone marrow is an independ...
We report comparative efficacy between high-dose cyclophosphamide (HDCyC), low-dose cyclophosphamide (LDCyC), mycophenolate mofetil (MMF) and rituximab in patients with lupus nephritis (LN).
The aim of our study was to evaluate the efficacy and toxicity of TECAM (thiotepa, etoposide, cyclophosphamide, cytarabine, and melphalan) and BEAM (carmustine, etoposide, cytarabine, and melphalan) c...
Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.

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...
