Cyclophosphamide Clinical Trials

RATIONALE: Transplanted peripheral stem cells can sometimes be rejected by the body's tissues. Treating donor peripheral stem cells with filgrastim may increase the number of donor white blood cells. This may help to decrease the rejection of the transplanted cells in patients receiving them as treatment for acute leukemia. PURPOSE: Phase II trial to study the effectiveness of filgrastim-treated donor peripheral stem cells in treating patients with acute leukemia who are undergoing peripheral stem cell transplantation.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. PURPOSE: Phase II trial to study the effectiveness of chemotherapy followed by peripheral stem cell transplantation in treating patients who have myelodysplastic syndrome. Read Less

RATIONALE: Combining antithymocyte globulin with combination chemotherapy before donor peripheral stem cell transplantation may reduce the chance of developing graft-versus-host disease following transplantation. PURPOSE: Phase I/II trial to study the effectiveness of combining antithymocyte globulin with busulfan and cyclophosphamide in reducing graft-versus-host disease in patients who are undergoing donor stem cell transplantation for myelodysplastic syndrome or other myeloproliferative disorder.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Biological therapies such as interleukin-2 use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, peripheral stem cell transplantation, and interleukin-2 in treating patients who have solid tumors or lymphoma.

RATIONALE: Drugs used in chemotherapy, such as clofarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of clofarabine and cyclophosphamide in treating patients with relapsed or refractory acute leukemia, chronic myelogenous leukemia, or myeloproliferative disorders.

RATIONALE: Giving total-body irradiation and chemotherapy, such as cyclophosphamide, before a donor stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells and helps stop the growth of cancer or abnormal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving immunosuppressive therapy before or after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving total-body irradiation together with cyclophosphamide works in treating patients who are undergoing donor stem cell transplant for hematologic cancer and other diseases.

This study is for patients with Severe Aplastic Anemia (SAA). A stem cell transplant from a genetically matched sibling donor can help or cure this disease in 85 to 100 percent of patients. Stem cells are immature blood cells that grow to become red blood cells, white blood cells or platelets. A genetic "match" means a brother or sister has same immune type (HLA type) as the patient. Unfortunately, few patients have a matched sibling donor. The chance of negative outcomes is much higher with other types of donors. This study will test the success of a new approach to stem cell transplant for SAA. Patients in this study will receive drugs and radiation treatment to destroy their diseased bone marrow and to prepare them for stem cell transplant. Bone marrow is the tissue inside the bones where stem cells are made.Stem cells will be harvested from the blood or bone marrow of genetically matched unrelated donors or partially matched family donors. The stem cells will be filtered using a new device that is currently under study. The patients will receive large doses of the filtered stem cells (stem cell graft). Researchers want to find out how the study treatment affects patients, the disease, and the chances for survival. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining bone marrow or peripheral stem cell transplantation with chemotherapy may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus either bone marrow or peripheral stem cell transplantation in treating patients with myeloproliferative disorders. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of umbilical cord blood transplantation plus combination chemotherapy in treating patients who have hematologic cancer or nonmalignant hematologic disease. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known which regimen of combination chemotherapy is more effective for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two regimens of combination chemotherapy followed by peripheral stem cell transplantation in treating patients who have stage II or stage IIIA breast cancer. Read Less

RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of bone marrow transplantation in treating patients who have hematologic cancer. Read Less

RATIONALE: Monoclonal antibodies can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody therapy, cyclophosphamide, and total-body irradiation followed by peripheral stem cell transplantation in treating patients who have advanced recurrent acute lymphocytic leukemia.
