About

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of chemotherapy followed by peripheral stem cell transplantation in treating patients who have recurrent or refractory AIDS-related lymphoma.

Full description

OBJECTIVES:

• Determine the safety and tolerability of intensive chemotherapy and autologous peripheral blood stem cell transplantation in patients with recurrent or refractory AIDS-related lymphoma.
• Determine the response and response duration in these patients treated with this regimen.
• Determine the effect of this treatment regimen on HIV RNA and CD4 cells in these patients.

OUTLINE: Patients receive mobilization chemotherapy consisting of cyclophosphamide IV over 2 hours followed 2 days later by daily filgrastim (G-CSF) subcutaneously (SC) until blood counts recover. Patients then undergo leukopheresis to collect CD34+ cells.

Patients receive conditioning chemotherapy consisting of oral busulfan every 6 hours on days -7, -6, -5, and -4 for a total of 14 doses and cyclophosphamide IV over 1 hour on days -3 and -2. Patients undergo autologous stem cell infusion on day 0. G-CSF is administered IV or SC daily beginning on day 1 and continuing until blood counts recover.

Patients are followed monthly for 1 year and then every 6 months for 2 years.

PROJECTED ACCRUAL: A total of 5-25 patients will be accrued for this study.

Sex: All

Ages: 18 to 120 years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS:

• Intermediate- or high-grade non-Hodgkin's lymphoma or Hodgkin's disease

  • Failed to achieve complete remission with initial therapy OR
  • Relapsed after initial therapy

• May be in complete remission after salvage therapy

• Sensitive to most recent chemotherapy

  • Improvement of at least 25% in bidimensional tumor measurements OR
  • Improvement in evaluable disease sustained over 4 weeks

• Measurable or evaluable disease

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.
