OBJECTIVES: Primary * Determine tumor regression in patients with metastatic melanoma treated with nonmyeloablative lymphodepleting chemotherapy comprising cyclophosphamide and fludarabine followed by autologous CD25-positive-T-regulatory-cell-depleted lymphocyte reinfusion and high-dose interleukin-2. Secondary * Determine the rate of repopulation of CD25-positive T-regulatory cells in patients treated with this regimen. * Determine the toxicity of this regimen in these patients. OUTLINE: * Apheresis and CD25-positive T-regulatory cell depletion: Patients undergo 1-2 aphereses to collect peripheral blood mononuclear cells (PBMC). CD25-positive T-regulatory cells are depleted from the collected PBMC in vitro. * Nonmyeloablative lymphodepleting chemotherapy: Patients receive cyclophosphamide IV over 1 hour on days -8 and -7 and fludarabine IV over 15-30 minutes on days -6 to -2. * Autologous CD25-positive-T-regulatory-cell-depleted lymphocyte reinfusion: Patients receive autologous lymphocytes IV over 20-30 minutes on day 0. * Filgrastim (G-CSF) and high-dose interleukin-2 (IL-2) therapy: Patients receive G-CSF subcutaneously (SC) daily beginning on day 0 and continuing until blood counts recover. Patients also receive high-dose IL-2 IV over 15 minutes 3 times daily on days 0-4 and 14-18. Patients are reevaluated 4-6 weeks after completion of high-dose IL-2 therapy. Patients achieving stable disease or a partial response may receive additional high-dose IL-2 as above for up to 2 retreatment courses in the absence of disease progression or unacceptable toxicity. Retreatment begins at least 6 weeks after autologous lymphocyte reinfusion. After completion of study treatment, patients are followed at 4-6 weeks and then every 1-2 months thereafter. PROJECTED ACCRUAL: A total of 16-29 patients will be accrued for this study within 1-1.5 years.
