OBJECTIVES:

Primary

• Determine the safety of donor lymphocyte infusion, in terms of the incidence of life-threatening graft-versus-host disease (GVHD), in patients with persistent, relapsed, or progressing malignancy after nonmyeloablative allogeneic transplantation.

Secondary

• Determine disease response and progression-free and overall survival of patients treated with this regimen.
• Determine chimerism in patients treated with this regimen.
• Determine the grade of GVHD and infections in patients treated with this regimen.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive unirradiated (viable) donor lymphocyte infusion (DLI) over 15-30 minutes on day 0. Patients may receive a second infusion after 4 weeks if no graft-versus-host disease (GVHD) develops and disease worsens, or after 8 weeks if disease status is unchanged and persistent donor T cells are documented.

To determine the safety of this regimen, all patients receive a standard initial dose of DLI and then, among patients requiring a second treatment, cohorts of 5-25 patients receive decreasing doses of DLI. Acceptable safety is determined by the regimen during which no more than 15% of patients experience morbid GVHD.

Patients are followed every 2 months for 6 months, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 5-100 patients will be accrued for this study.
