Filter by:The protocol aims at reducing transplant toxicity and mortality in patients with multiple myeloma.
Prospective multicenter phase 2 study using PAD and Thal/Dex combination sequentially.
Protocol DSMM VIII is a multi-center, open-label study evaluating the safety and tolerability, as well as the efficacy, of maintenance treatment with VELCADE (bortezomib) in patients with multiple myeloma with detectable disease activity following tandem high-dose chemotherapy and autologous SCT. The time from SCT to the initiation of VELCADE treatment will be 3 to 6 months.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and cyclophosphamide, and radiation therapy before a donor umbilical cord 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 system 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 cyclosporine and mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by cyclosporine and mycophenolate mofetil works in treating patients who are undergoing a donor umbilical cord blood transplant for hematologic cancer.
Background: Multiple myeloma (MM) is a clonal plasma cell neoplasm characterized by proliferation of neoplastic plasma cells in bone marrow (BM). So far, it is an incurable disease and the median survival time of MM patients is only three to four years. Till now, whether the extent of angiogenesis in BM of MM patients serves as an important and independent prognostic factor is still debated. In this study, we would like to have the BM perfusion status imaged by dynamic MRI to mimic the macroscopic vascular densities of BM, and thereafter, the BM perfusion status, the clinical outcome of the MM patients, and the angiogenesis related biological markers will be correlated. Methods: About 35 to 50 MM patients, included newly diagnosed patients or the patients who will undertake the special treatment, are enrolled in this study. The thoraco-lumbar spine is scanned by the MRI, and the BM perfusion status is obtained by contrast-enhanced dynamic MRI. Meanwhile, the patients undertake BM biopsy at one site or two sites and the BM aspirates are also obtained and separated into BM plasma and BM mononuclear cells (BMMC) by Ficoll-Hypaque centrifugation. The angiogenesis related genes expression profiles of the BMMC will be determined by cDNA microarrays and some of them, like VEGF, bFGF, and PDGF, will be semiquantified by real-time PCR. The levels of related proteins will be determined by ELISA. The BM plasma samples are further applied to proteomic analysis to screen the novel molecules with clinical relevance. Prospects: BM perfusion patterns imaged by dynamic MRI can predict the clinical outcome of MM, and are correlated with the angiogenesis relevant biological markers in BM.
Background: In some studies, thalidomide in combination with chemotherapy has been shown to be effective in patients with relapsed or refractory multiple myeloma (MM). In this study, the researchers have chosen a regimen which can be administered on an outpatient basis. Induction therapy: To evaluate the efficacy and toxicity of thalidomide, cyclophosphamide, oral idarubicin and dexamethasone (T-CID) in patients with relapsed or refractory multiple myeloma. Maintenance therapy: Randomized trial to compare efficacy and toxicity of thalidomide and thalidomide plus oral idarubicin as maintenance therapy in patients with at least stable disease after T-CID.
RATIONALE: Light-emitting diode (LED) therapy may be able to prevent mucositis of the mouth. PURPOSE: Randomized phase II trial to determine the effectiveness of LED therapy in preventing mucositis of the mouth in children who are receiving chemotherapy with or without radiation therapy before donor bone marrow transplantation.
