Brief summary: RATIONALE: An infusion of a patient's lymphocytes that have been treated in the laboratory to remove certain immune cells may be an effective treatment for melanoma. Drugs, such as cyclophosphamide and fludarabine, may suppress the immune system so that the patient's immune cells allow the infused lymphocytes to work. Interleukin-2 may help the lymphocytes kill more tumor cells when they are put back in the body. Giving cyclophosphamide and fludarabine followed by an autologous lymphocyte infusion and interleukin-2 may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving cyclophosphamide and fludarabine followed by an autologous lymphocyte infusion and interleukin-2 works in treating patients with refractory or recurrent melanoma.

Detailed description: 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.
