RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Total-body irradiation directs high-energy x-rays to the entire body to kill tumor cells. Biological therapies, such autologous lymphocytes that have been treated in the laboratory, may stimulate the immune system in different ways and stop tumor cells from growing. Aldesleukin may stimulate the lymphocytes to kill tumor cells. An autologous stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy.
PURPOSE: This phase II trial is studying how well chemotherapy and total-body irradiation followed by autologous lymphocyte infusion, aldesleukin, and autologous stem cell transplant work in treating patients with metastatic melanoma.

OBJECTIVES:
Primary
- Determine whether treatment with a myeloablative lymphocyte-depleting preparative regimen comprising chemotherapy and total-body irradiation followed by autologous tumor-reactive tumor-infiltrating lymphocytes, high-dose aldesleukin, and autologous stem cell transplantation results in complete clinical tumor regression in patients with metastatic melanoma.
- Evaluate the safety of this regimen in these patients.
Secondary
- Determine the survival in patients of infused cells following the administration of a myeloablative regimen, using analysis of the sequence of the variable region of the T-cell receptor or flow cytometry.
OUTLINE: Patients are stratified according to prior therapy with aldesleukin (yes vs no).
- Autologous stem cell collection: Patients receive filgrastim (G-CSF) subcutaneously (SC) twice daily for 7 days. Beginning on day 5 of G-CSF, patients undergo apheresis daily for up to 3 days. If an adequate number of stem cells are not collected, patients may receive 1 additional course of G-CSF mobilization and apheresis or undergo bone marrow harvest.
- Lymphocyte-depleting myeloablative preparative regimen: Patients receive cyclophosphamide IV over 1 hour on days -7 and -6 and fludarabine IV over 15-30 minutes on days -7 to -3. Patients also undergo total-body irradiation twice daily on days -3 to -1.
- Autologous lymphocyte infusion: Patients receive autologous tumor-reactive tumor-infiltrating lymphocytes IV over 20-30 minutes on day 0.
- Aldesleukin therapy: Patients receive high-dose aldesleukin IV over 15 minutes 3 times daily on days 0-4 (maximum of 15 doses).
- Autologous stem cell transplantation: Patients undergo autologous CD34+ stem cell or bone marrow transplantation on day 1 followed by G-CSF SC once daily until blood counts recover.
After completion of study therapy, patients are followed periodically.
PROJECTED ACCRUAL: A total of 108 patients will be accrued for this study.
