Cyclophosphamide Treatment Options in California

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.

RATIONALE: Drugs used in chemotherapy 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), and giving the drugs in different combinations may kill more cancer cells. PURPOSE: This phase II trial is studying how well combination chemotherapy works in treating patients with newly diagnosed acute lymphoblastic leukemia. Read Less

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

RATIONALE: OTI-010 may be effective for graft-versus-host disease prophylaxis (prevention) in patients who are undergoing donor peripheral stem cell transplantation for hematologic malignancies (cancer of the blood or bone marrow). PURPOSE: This randomized phase II trial is studying how well OTI-010 works in preventing graft-versus-host disease in patients who are undergoing donor peripheral stem cell transplantation for hematologic cancer.

The purpose of this study is to determine if the intra-tumoral injection of a subject's own dendritic cells after cryotherapy of the prostate is a safe and effective treatment for advanced prostate cancer. In theory, the injected dendritic cells will internalize antigens from the tumor cells which have been damaged by cryotherapy and activate the subject's immune system against that specific tumor. Subjects will also receive a low dose chemotherapy designed to lower the number of T-regulatory cells which have been shown to lower or stop some immune system responses. Hypothesis 1: Dendritic cell injection into cryotreated prostate cancer is non-toxic; Hypothesis 2: Dendritic cell injection into cryotreated prostate cancer is medically beneficial to the subject.

The primary objective of this study was to evaluate the safety and efficacy of the combination of fludarabine and cyclophosphamide in previously untreated CLL patients. Participants will receive fludarabine and cyclophosphamide on days 1, 2, and 3 of six 28-day cycles. Read Less

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed. Giving combination chemotherapy after surgery may kill any remaining tumor cells. PURPOSE: This phase II trial is studying how well surgery and/or combination chemotherapy work in treating children with fibrosarcoma. Read Less

This clinical trial is studying the side effects of combination chemotherapy and to see how well they work in treating patients with newly diagnosed localized Ewing sarcoma family of tumors. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving the drugs in different ways may kill more tumor cells. Read Less

Phase II trial to study the effectiveness of combining rituximab and rasburicase with combination chemotherapy in treating young patients who have newly diagnosed advanced B-cell leukemia or lymphoma. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug with rituximab may kill more cancer cells. Chemoprotective drugs such as rasburicase may protect kidney cells from the side effects of chemotherapy. Read Less

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. 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 tacrolimus, sirolimus, antithymocyte globulin, and methotrexate before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well sirolimus, tacrolimus, and antithymocyte globulin work in preventing graft-versus-host disease in patients undergoing a donor stem cell transplant for hematological cancer .

Patients with 3 or more adverse prognostic factors have a higher relapse rate. Significant anti-tumor activity in Hodgkin's lymphoma has been reported with two new drugs:gemcitabine and vinorelbine. The introduction of these new agents with their different mechanisms of action into the Stanford V regimen may increase effectiveness while maintaining a favorable toxicity profile with respect to fertility and a low risk of secondary leukemia. On this basis, we propose a new regimen, Stanford VI, for patients with bulky and advanced HD with 3 or more risk factors. 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
