Cyclophosphamide Treatment Options in Denver, CO

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. It is not yet known if total-body irradiation plus peripheral stem cell transplantation is more effective with busulfan or with cyclophosphamide for myelodysplastic syndrome or acute myeloid leukemia. PURPOSE: Randomized phase III trial to compare the effectiveness of busulfan with that of cyclophosphamide in patients undergoing total-body irradiation plus peripheral stem cell transplantation for advanced myelodysplastic syndrome or related acute myeloid leukemia.

This phase I multicenter feasibility trial is studying the safety and potential efficacy of infusing ex vivo expanded cord blood progenitors with one unmanipulated umbilical cord blood unit for transplantation following conditioning with fludarabine, cyclophosphamide and total body irradiation (TBI), and immunosuppression with cyclosporine and mycophenolate mofetil (MMF) for patients with hematologic malignancies. Chemotherapy, such as fludarabine and cyclophosphamide, and TBI given before an umbilical cord blood transplant stops the growth of leukemia cells and works to prevent the patient's immune system from rejecting the donor's stem cells. The healthy stem cells from the donor's umbilical cord blood help the patient's bone marrow make new red blood cells, white blood cells, and platelets. It may take several weeks for these new blood cells to grow. During that period of time, patients are at increased risk for bleeding and infection. Faster recovery of white blood cells may decrease the number and severity of infections. Studies have shown that counts are more likely to recover more quickly if increased numbers of cord blood cells are given with the transplant. We have developed a way of growing or "expanding" the number of cord blood cells in the lab so that there are more cells available for transplant. We are doing this study to find out whether or not giving these expanded cells along with one unexpanded cord blood unit is safe and if use of expanded cells can decrease the time it takes for white blood cells to recover after transplant. We will study the time it takes for blood counts to recover, which of the two cord blood units makes up the patient's new blood system, and how quickly immune system cells return Read Less

This phase II trial is studying how well giving bortezomib together with liposomal doxorubicin hydrochloride, dexamethasone, and cyclophosphamide works in treating patients with multiple myeloma that relapsed after autologous stem cell transplant. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as liposomal doxorubicin hydrochloride, dexamethasone, 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 bortezomib together with liposomal doxorubicin hydrochloride, dexamethasone, and cyclophosphamide may kill more cancer cells. Read Less

RATIONALE: Giving chemotherapy, such as fludarabine phosphate, busulfan, and cyclophosphamide, and total-body radiation therapy before a donor peripheral 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 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. It is not yet known whether low-dose chemotherapy and total-body radiation therapy is more effective than high-dose chemotherapy in treating patients with myelodysplastic syndrome or acute myeloid leukemia. PURPOSE: This phase III trial is studying low-dose conditioning to see how well it works compared to high-dose conditioning followed by peripheral blood stem cell transplant in treating patients with myelodysplastic syndromes or acute myeloid leukemia Read Less

RATIONALE: Radiation therapy uses high energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known which chemotherapy regimen is more effective when combined with radiation therapy for treating medulloblastoma. PURPOSE: Randomized phase III trial to compare two combination chemotherapy treatments plus radiation therapy in treating children with newly diagnosed medulloblastoma. Read Less

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 allow doctors to give higher doses of chemotherapy and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by peripheral stem cell transplantation in treating children who have recurrent or refractory Hodgkin's lymphoma or non-Hodgkin's lymphoma. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Combination chemotherapy plus surgery may be an effective treatment for neuroblastoma. PURPOSE: This phase III trial is studying how well combination chemotherapy followed by surgery works in treating young patients with neuroblastoma. Read Less

RATIONALE: Radiation therapy uses x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow doctors to give higher doses of radiation therapy and chemotherapy and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiation therapy, chemotherapy and peripheral stem cell transplantation in treating patients with primitive neuroectodermal tumors. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating children who have lymphoma. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. 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 therapy regimen is most effective for treating patients with kidney tumors. PURPOSE: Phase III trial to compare the effectiveness of chemotherapy with or without radiation therapy, surgery, and/or peripheral stem cell or bone marrow transplantation in treating young patients with kidney tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy and kill more cancer cells. Radiation therapy uses high-energy x-rays to damage cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, bone marrow transplantation, and radiation therapy in treating infants with acute lymphoblastic leukemia. Read Less
