Filter by:RATIONALE: Immunosuppressive therapy may improve bone marrow abnormalities and may be an effective treatment for myelodysplastic syndrome. PURPOSE: Phase II trial to study the effectiveness of antithymocyte globulin plus cyclosporine in treating patients who have myelodysplastic syndrome.
Phase II trial to study the effectiveness of thalidomide in treating patients who have myelodysplastic syndrome. Thalidomide may improve the immune system's ability to fight myelodysplastic syndrome
RATIONALE: Monoclonal antibodies such as bevacizumab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining monoclonal antibody therapy with chemotherapy may be an effective treatment for hematologic cancer. PURPOSE: Phase II trial to study the effectiveness of bevacizumab combined with cytarabine and mitoxantrone in treating patients who have hematologic cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of MS-275 in treating patients who have hematologic cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining monoclonal antibody therapy with chemotherapy may kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combining chemotherapy and monoclonal antibody therapy in treating patients who have advanced myeloid cancer.
RATIONALE: Music therapy may be effective in relieving pain and emotional distress in patients who are undergoing cancer therapy. PURPOSE: Randomized trial to determine the effectiveness of music therapy to ease pain and emotional distress in patients with hematologic cancer who are undergoing high-dose therapy and stem cell transplantation.
RATIONALE: 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 cancer cells. PURPOSE: Phase II trial to study the effectiveness of busulfan and melphalan followed by donor bone marrow transplantation in treating patients who have advanced hematologic cancer.
This clinical trial studies fludarabine phosphate and total-body radiation followed by donor peripheral blood stem cell transplant and immunosuppression in treating patients with hematologic malignancies. Giving 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 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 total-body irradiation together with fludarabine phosphate, cyclosporine, and mycophenolate mofetil before transplant may stop this from happening.
Background: - Allogeneic blood and marrow stem cell transplantation (BMT) plays an important role in the curative treatment of a number of pediatric malignancies. Unfortunately, the success of conventional allogeneic BMT is limited in part by the multiple toxicities associated with myeloablative preparative regimens. - Non-myeloablative pre-transplant regimens are associated with less toxic side effects than standard BMT. Recently, a novel immunosuppressive, non-myeloablative pre-transplant chemotherapy regimen has been shown to facilitate complete donor engraftment in an adult trial at the NCI. Objectives: The primary objective of this protocol is to evaluate the efficacy and safety of this treatment approach in pediatric patients with hematopoietic malignancies Eligibility: Inclusion Criteria Age: Patient must be greater than or equal to 5 years and less than 22 years of age. Diagnosis: - Hodgkin s and Non-Hodgkin s Lymphoma: Refractory disease or relapse after salvage regimen. - Acute Myelogenous Leukemia: History of bone marrow relapse in remission (CR) #2 or greater. - Acute Lymphocytic Leukemia: History of bone marrow relapse in CR #2 or greater (CR#1 with Philadelphia chromosome positive or prior induction failure). - Acute Hybrid Leukemia including mixed lineage, biphenotypic and undifferentiated: History of bone marrow relapse in CR #2 or greater (CR#1 with Philadelphia chromosome positive or prior induction failure). - Myelodysplastic Syndrome: RAEB or RAEB-t with less than 10% blasts in marrow and blood. - Chronic Myelogenous Leukemia: Chronic phase or accelerated phase with less than 10% blasts in marrow and blood. - Juvenile Myelomonocytic Leukemia: less than 10% blasts in marrow and blood. Prior Therapy: Chemotherapy to achieve above criteria allowed. Prior BMT allowed as long as at least day 100+ post-prior BMT, no evidence of GVHD, and no detectable residual donor chimerism. Donor: First degree related donors, who are HLA matched (single HLA-A or B locus mismatch allowed), weight greater than or equal to 15 kilograms, and who meet standard donation criteria will be considered. The same donor from a prior BMT is allowed. ECOG Performance Status: 0, 1, or 2. and life expectancy: greater than 3 months. Liver Function: Serum direct bilirubin less than 2.0 mg/dL and serum ALT and AST values less than or equal to 2.5x upper limit of normal. (Values above these levels may be accepted if due to malignancy.) Renal Function: Age adjusted normal serum creatinine or Cr clearance greater than or equal to 60 mL/min/1.73 m(2). Pulmonary Function: DLCO greater than or equal to 50%. Cardiac Function: LVEF greater than or equal to 45% by MUGA or LVSF greater than or equal to 28% by ECHO Exclusion Criteria - Active CNS malignancy: Tumor mass on CT or leptomeningeal disease. (Patients with a history of CNS involvement and no current evidence of CNS disease are allowed.) - HIV infection, active hepatitis B or C infection: HbSAg or HCV seropositive and elevated liver transaminases. - Fanconi Anemia. - Lactating or pregnant females. Design: Pilot Study - Initial evaluation: Patient and donor will be screened for eligibility. G-CSF primed bone marrow derived stem cells will be collected from the donor. - Induction/Consolidation chemotherapy: 1 to 3 cycles will be given every 22 days depending on disease response, CD4 count, and toxicities. - Lymphoma: fludarabine, etoposide, doxorubicin, vincristine, cyclophohamide, prednisone, and filgrastim (EPOCH-fludarabine). - Leukemia and MDS: Fludarabine, cytarabine, and filgrastim (FLAG). - Transplantation: Fludarabine and cyclophosphamide will be administered over 4 days followed by bone marrow transplant. Patients will remain hospitalized until bone marrow recovery. Patients will be monitored closely at the NIH for at least 100 days post-BMT. - Post-transplant CNS prophylaxis for ALL: Standard post-transplant CNS prophylaxis will be employed with intrathecal methotrexate to decrease the risk of CNS relapse for all patients with ALL. - Total number of recipient and donors to be accrued is 56.
Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Phase I trial to study the effectiveness of bryostatin 1 combined with sargramostim in treating patients who have refractory myeloid cancer
