Filter by:RATIONALE: Collecting and storing samples of tissue, blood, and body fluid from patients with cancer to study in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing blood and tissue samples from patients being evaluated for hematologic cancer.
RATIONALE: Giving chemotherapy and bortezomib before a peripheral stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as G-CSF, and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and bortezomib. It is not yet known whether high-dose melphalan given together with a second stem cell transplant is more effective than low-dose cyclophosphamide in treating patients with relapsed multiple myeloma. PURPOSE: This randomized phase III trial is studying giving high-dose melphalan together with a second stem cell transplant to see how well it works compared with low-dose cyclophosphamide in treating patients with relapsed multiple myeloma after chemotherapy.
RATIONALE: Giving chemotherapy, such as fludarabine, busulfan, and cyclophosphamide, together with antithymocyte globulin before a donor stem cell transplant helps stop the growth of cancer and abnormal cells. Giving chemotherapy before or after transplant 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 and abnormal 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 the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well stem cell transplant works in treating patients with hematological cancer or other disorders.
RATIONALE: Drugs used in chemotherapy, such as melphalan, use different ways to stop cancer cells from dividing so they stop growing or die. Stem cell transplant using stem cells from the patient may be able to replace immune cells that were destroyed by chemotherapy used to kill cancer cells. Giving colony-stimulating factors, such as G-CSF or pegfilgrastim, helps stem cells move from the bone marrow to the blood so they can be collected. It is not yet known which regimen is more effective in treating multiple myeloma. PURPOSE: This randomized phase II trial is studying how well high-dose chemotherapy followed by stem cell transplant works in treating patients with newly diagnosed stage I, stage II, or stage III multiple myeloma.
RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Drugs used in chemotherapy, such as dexamethasone, 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 dexamethasone may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with dexamethasone works in treating patients with multiple myeloma that has relapsed or has not responded to treatment.
RATIONALE: Drugs used in chemotherapy, such as doxorubicin hydrochloride liposome and melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving doxorubicin hydrochloride liposome and melphalan together with bortezomib may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of doxorubicin hydrochloride liposome , melphalan, and bortezomib and to see how well they work in treating patients with relapsed or refractory stage I, stage II, or stage III multiple myeloma.
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.
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.
