Donor Bone Marrow Transplant in Treating Patients with High-Risk Solid Tumors

Trial Status: active

This phase II trial studies how well a donor bone marrow transplant works in treating patients with solid tumors that are likely to recur (come back) or spread. Giving low doses of chemotherapy and total body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells when they do not exactly match the patient's blood. The donated stem cells may replace the patient's immune cells 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 sirolimus and mycophenolate mofetil before transplant may stop this from happening.
