Filter by:RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher doses of chemotherapy to be given so that more plasma cells are killed. By reducing the number of plasma cells, the disease may progress more slowly. PURPOSE: This phase II trial is studying how well autologous stem cell transplant works in treating patients with persistent or recurrent primary systemic (AL) amyloidosis.
RATIONALE: Darbepoetin alfa and epoetin alfa may stimulate red blood cell production and treat anemia in patients who are receiving chemotherapy. It is not yet known whether darbepoetin alfa is more effective than epoetin alfa in treating patients with anemia. PURPOSE: Randomized phase III trial to compare the effectiveness of darbepoetin alfa with that of epoetin alfa in treating anemia in patients who are receiving chemotherapy for cancer.
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Ultraviolet-B light therapy given before and after allogeneic stem cell transplantation may help prevent this from happening. PURPOSE: Clinical trial to study the effectiveness of combining ultraviolet-B light therapy with allogeneic stem cell transplantation in treating patients who have hematologic malignancies.
In recent years PBPC have replaced bone marrow as the source of hematopoietic stem cells for autologous transplantation. One of the cited advantages of this procedure is the avoidance of bone marrow harvest, which frequently requires general anesthesia. Other advantages include faster neutrophil and platelet engraftment times, faster immune recovery, decrease in the amount of tumor contamination and technical ability to obtain stem cells from patients previously considered unharvestable because of marrow fibrosis or because of prior radiotherapy to the pelvis. Filgrastim has emerged as the preferred cytokine for stem cell mobilization based on its safety profile and the positive experience in granulocyte donors however, the number of circulating CD34+ cells does not occur until the third day after starting filgrastim injections. Pegfilgrastim stimulates the production and maturation of neutrophil precursors and enhances the functions of mature neutrophils in the same manner as filgrastim. Data form normal volunteers and in studies of patients with cancer have shown prolonged serum levels of the cytokine, with "self-regulation" of pegfilgrastim levels as a function of the neutrophil count. This confers a therapeutic advantage in clinical settings by allowing a less frequent dosing.
Drugs used in chemotherapy such as FR901228 use different ways to stop cancer cells from dividing so they stop growing or die. Phase II trial to study the effectiveness of FR901228 in treating patients who have relapsed or refractory multiple myeloma
RATIONALE: Voriconazole may be effective in preventing systemic fungal infections following chemotherapy. PURPOSE: Phase II trial to study the effectiveness of voriconazole in preventing systemic fungal infections in children who have neutropenia after receiving chemotherapy for leukemia, lymphoma, or aplastic anemia or in preparation for bone marrow or stem cell transplantation.
For each subject the study will consist of two phases: a treatment phase and a follow-up phase. Screening procedures will take place within 28 days of baseline. Treatment Phase: Subjects who qualify for enrollment into the study will receive single-agent CC-5013 in 28-day cycles. Study visits will occur every 4 weeks and hematologic and myeloma paraprotein laboratory assessments will occur every 2 weeks for the first 6 cycles and every 4 weeks thereafter. Follow-Up Phase: All subjects who discontinue the treatment phase for any reason will continue to be followed for survival and post-treatment phase anti-myeloma treatment.
RATIONALE: Drugs used in chemotherapy such as melphalan work in different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with donor peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: This phase II trial is studying how well giving melphalan together with autologous stem cell transplantation works in treating patients with multiple myeloma or primary systemic amyloidosis.
RATIONALE: Antifungals such as ravuconazole may be effective in preventing fungal infections in patients undergoing chemotherapy and stem cell transplantation. PURPOSE: Phase I/II trial to study the effectiveness of ravuconazole in preventing fungal infections in patients undergoing allogeneic stem cell transplantation.
RATIONALE: Drugs used in chemotherapy such as dexamethasone use different ways to stop cancer cells from dividing so they stop growing or die. Lenalidomide may stop the growth of multiple myeloma by stopping blood flow to the tumor. It is not yet known whether dexamethasone is more effective with or without lenalidomide in treating multiple myeloma. PURPOSE: This randomized phase III trial is studying dexamethasone and lenalidomide to see how well they work compared to dexamethasone alone in treating patients with previously untreated stage I, stage II, or stage III multiple myeloma.
