Protocol Number: 01-H-0162
Patients with leukemia, lymphoma or a myelodysplastic syndrome (pre-cancerous blood disorder) between 55 and 75 years of age may be eligible for this 4-year study. Candidates will be screened with a medical history and physical examination, dental and eye examinations, blood tests (including HLA typing for genetic compatibility with the donor), stress test, echocardiogram, 24-hour electrocardiogram (EKG), breathing test and chest and sinus X-rays. They will also have a bone marrow biopsy and aspiration, in which about a tablespoon of bone marrow will be withdrawn through a needle inserted into the hipbone. This procedure is done under local anesthetic. Participants will undergo apheresis to collect lymphocytes to test for interactions between the patient's and donor's white cells. In this procedure, blood is drawn through a needle in the arm, similar to donating a unit of blood. The lymphocytes are then separated by a cell separator machine and collected, and the rest of the blood is returned through a needle in the other arm. Patients will also have a central venous catheter (flexible plastic tube) placed in a vein before treatment begins. This line will remain in place during the stem cell transfusion and recovery period to draw and transfuse blood, give medications, and to infuse the donated cells. Seven days before the transfusion, patients will begin chemotherapy with cyclophosphamide and will start taking fludarabine 5 days before the procedure. These anti-cancer agents are given to kill the cancer cells and to prevent rejection of the donated cells. The day after chemotherapy is completed, the stem cells will be infused through the central line. Also, from 4 days before the transplantation until about 3 months after the procedure, patients will receive cyclosporine to help prevent both GVHD and rejection of the donated cells. Usually patients may be discharged from the hospital about 3 weeks after the transplant. They will return for follow-up clinic visits weekly or twice weekly for 3 months for a symptom check, physical examination and blood tests. Blood transfusions will be given if needed. Subsequent visits will be scheduled at 4, 6, 12, 18, 24, 30, 36 and 48 months after the transplant, or more often if required, and then yearly.
