Combination Chemotherapy and Bone Marrow and/or Peripheral Stem Cell Transplantation in Treating Patients With Non-Hodgkin's Lymphoma

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Bone marrow and peripheral stem cell transplantation may allow doctors to give high doses of chemotherapy and kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy with cyclophosphamide, etoposide and cisplatin followed by bone marrow and/or peripheral stem cell transplantation in patients with relapsed or refractory intermediate- or high-grade non-Hodgkin's lymphoma.

OBJECTIVES:

* Determine the curative potential of high-dose cyclophosphamide, etoposide, and cisplatin (CEP) with syngeneic or autologous bone marrow and/or autologous peripheral blood stem cell rescue in patients with relapsed or refractory, stage I-IV, intermediate- or high-grade non-Hodgkin's lymphoma.
* Determine the overall response rate and survival of patients treated with this regimen.
* Determine the toxic effects of this regimen in these patients.
* Determine the differences in the rates of engraftment, response, and survival of patients treated with bone marrow vs peripheral blood stem cell transplantation.
* Determine the response rate and survival of patients treated with consolidative radiotherapy after recovery from transplantation.
* Determine the toxic effects of consolidative radiotherapy after recovery from transplantation in these patients.

OUTLINE: Syngeneic or autologous bone marrow and/or autologous peripheral blood stem cells (PBSC) are harvested. Syngeneic bone marrow transplantation is preferred for patients with a qualifying identical twin donor. Patients without a syngeneic donor who have a history of lymphomatous involvement of the bone marrow and are profoundly hypocellular undergo harvest of PBSC alone. Patients without a syngeneic donor who have no history of lymphomatous involvement of the bone marrow undergo harvest of autologous bone marrow or PBSC.

Patients receive conditioning comprising cyclophosphamide IV over 1 hour on days -6 to -3 and etoposide IV over 1 hour every 12 hours and cisplatin IV continuously on days -6 to -4. Bone marrow and/or PBSC are infused on day 0. (Patients requiring more than 25 bags of stem cells receive bone marrow transplantation on day 0 and PBSC transplantation on day 1.)

After recovery from transplantation, eligible patients receive consolidative radiotherapy to any site of prior bulk disease (greater than 5 cm) present at any time before transplantation and any site of disease present at the time of transplantation.

Patients are followed at 3, 6, and 12 months and then annually thereafter.

PROJECTED ACCRUAL: A maximum of 30 patients will be accrued for this study.

Eligibility Criteria:
DISEASE CHARACTERISTICS:

* Histologically proven relapsed or refractory, stage I-IV, intermediate- or high-grade non-Hodgkin's lymphoma

  * Eligible subtypes:

    * Diffuse small cleaved cell
    * Diffuse mixed (small and large cell)
    * Diffuse large cell
    * Large cell immunoblastic
    * Lymphoblastic
    * Small noncleaved cell
* High-grade histology patients should first be considered for Protocol TUHSC-1520
* Must have chemosensitive disease, defined by 1 of the following conditions:

  * Response to initial chemotherapy without obtaining complete response (CR)(refractory lymphoma)
  * Relapse after chemotherapy-induced CR if tumor volume reduced by at least 25% for more than 1 month after completion of 1-3 courses of salvage chemotherapy (chemosensitive relapse)
* No chemoresistant disease, defined by the following conditions:

  * Unresponsive or progressive disease during initial chemotherapy
  * Relapse after chemotherapy-induced CR if tumor volume not reduced by at least 25% after completion of 1-3 courses salvage chemotherapy (chemoresistant relapse)
* No CNS involvement by lymphoma
* Syngeneic bone marrow transplantation offered to patients with consenting identical twin donor NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
