简要总结
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.
详细描述
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.
