Peripheral Stem Cell Transplantation Followed By Infusion of White Blood Cells in Treating Patients With AIDS-Related Lymphoma

RATIONALE: Donor peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. Sometimes the transplanted cells are rejected by the body's normal tissues. Treatment with donor white blood cells may prevent this from happening. PURPOSE: Phase II trial to study the effectiveness of donor peripheral stem cell transplantation followed by infusions of donor white blood cells in treating patients who have AIDS-related lymphoma.
