RATIONALE: Giving low doses of chemotherapy, such as fludarabine and cyclophosphamide, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving a monoclonal antibody, alemtuzumab, at the time of transplant may stop this from happening.

PURPOSE: This phase II trial is studying peripheral stem cell transplant and monoclonal antibody therapy to see how well they work in treating patients with high-risk hematologic cancer, refractory breast or kidney cancer, or melanoma.

OBJECTIVES:

• Determine the efficacy, in terms of mortality, occurrence of acute graft versus-host-disease, and grade 3/4 toxicity, of in vivo and in vitro alemtuzumab (monoclonal antibody CD52; Campath-1H) administered concurrently with nonmyeloablative fludarabine and cyclophosphamide, followed by HLA identical matched sibling allogeneic peripheral blood stem cell transplantation in patients with hematologic malignancies or refractory breast or renal cell cancer or melanoma.
• Determine the engraftment rate, response rate, and long term survival of patients receiving this regimen.
• Determine the recovery of immune function post engraftment in patients treated with this regimen.
• Determine the pharmacokinetics of cyclophosphamide administered in this regimen.
• Assess graft-versus-tumor effects in patients treated with this regimen.

OUTLINE: Patients receive alemtuzumab (monoclonal antibody CD52; Campath-1H) IV over 3 hours on days -6 to -2 and fludarabine IV over 30 minutes and cyclophosphamide IV over 1 hour on days -5 to -2. Allogeneic peripheral blood stem cells and alemtuzumab are infused on days 0 and 1. Filgrastim (G-CSF) is administered subcutaneously beginning on day 1 and continuing until blood counts recover.

Patients are followed daily until day 60, twice a week until day 100, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 70 patients will be accrued for this study within 3 years.
