Filter by:RATIONALE: Drugs used in chemotherapy, such as idarubicin and cytarabine, 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) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving idarubicin together with high-dose cytarabine works in treating patients with acute myeloid leukemia.
The study objective is to improve the global results obtained with LAL-AR-93 study, reaching an event free survival between 60-70%. Identify patients with bad prognosis, with minimal residual disease,who can benefit of allogenic bone marrow transplantation
Due to ALL Ph+ patients should receive a different treatment, is proposed a therapeutical protocol with: intensification treatment of induction to increment the CR rate, allogenic transplantation in first CR, autologous transplantation follow by alfa interferon in patients cannot done allogenic transplantation.
The goal of this study is to see if there is a benefit to giving chemotherapy and then natural killer (NK) cells. The NK cells must come from a family member who shares half of the patients HLA proteins. NK cells are a type of white blood cell. They can recognize and kill abnormal cells in the body. Patients whose blood cancer is not cured with a stem cell transplant do not have standard treatment options. Studies have shown that NK cells from a donor can be given safely and can be helpful in treating some blood diseases. These NK cells are collected from the patients donor and purified using a separation system called CliniMACS that has been used safely in previous studies and is used in this study with the approval of the Federal Food and Drug Administration. The researchers want to find out what effects the NK cells will have on blood cancer and bone marrow function and how to maximize its benefits in treating blood cancers. The researchers hope that giving chemotherapy and then NK cells will be a better treatment for the disease than the current available treatment options.

Primary Objective: 1. Evaluate the ability of Cyclophosphamide, Fludarabine, Alemtuzumab, and Rituximab (CFAR) to increase the proportion of patients with <5% CD5/CD19+ cells in bone marrow to 66% following 3 courses of treatment without significantly increasing the incidence of pneumonia or sepsis compared to a historic group of patients treated with the combination fludarabine, cyclophosphamide, and rituximab (FCR). Second Objectives: 1. Assess complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR. 2. Evaluate molecular remission in bone marrow by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responders treated with CFAR. 3. Assess immune parameters including blood T cell counts and subset distribution and serum immunoglobulin levels pretreatment, during treatment, and post-treatment in patients treated with CFAR.
RATIONALE: Giving chemotherapy before a donor stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps 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 cyclosporine and methotrexate before and after transplant may stop this from happening. PURPOSE: This clinical trial is studying the side effects and how well donor stem cell transplant works when given after conditioning therapy in treating patients with hematologic cancer, recurrent or metastatic solid tumor, or other disease.
Background: Major problems with stem cell transplantation (SCT) for cancer treatment are a lack of suitable donors for patients without a human leukocyte-antigen (HLA) tissue-matched sibling and graft-versus-host disease (GVHD), a serious side effects of immune-suppressing chemotherapy that is given to bring the cancer under control before SCT. In GVHD, the patients immune system attacks the transplanted donor cells. This study will try to improve the results of SCT from unrelated HLA-matched donors using targeted immune-depleting chemotherapy to bring the cancer under control before transplantation and to lower the chance of graft rejection, followed by reduced-intensity transplant chemotherapy to make the procedure less toxic. Objectives: To evaluate the safety and effectiveness of targeted immune-depleting chemotherapy followed by reduced-intensity transplant chemotherapy in patients with advanced cancers of the blood and immune system. To evaluate the safety and effectiveness of two different drug combinations to prevent GVHD. Both regimens have been successful in preventing GVHD, but they work by different mechanisms and affect the rebuilding of the immune system after the transplant. Eligibility: People 18 to 74 years of age with advanced or high-risk cancers of the blood and immune system who do not have a suitable HLA-matched sibling. Design: All patients receive chemotherapy before transplant to treat the cancer and suppress immune function. All patients receive a conditioning regimen of cyclophosphamide for 4 days and fludarabine for 4 days before SCT to prepare for the transplant. Patients are randomly assigned to one of two combination drug treatments to prevent GHVD as follows: - Group 1: Tacrolimus starting 3 days before SCT and continuing for 6 months, plus methotrexate on days 1, 3, 6, and 11 post-SCT, plus sirolimus starting 3 days before the SCT and continues for 6 months following SCT. - Group 2: Alemtuzumab for 4 days starting 8 days before SCT, plus cyclosporine starting 1 day before SCT and continuing for 6 months. Patients receive the donors stem cells and immune cells 2 days after completing the conditioning regimen. Patients are followed at the clinic regularly for the first 6 months after SCT, and then less often for at least 5 years. Some visits may include bone marrow aspirates and biopsies, blood draws, and other tests to monitor disease status. A skin biopsy, oral mucosa biopsy, and saliva collection are done to study chronic GVHD.
RATIONALE: Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the cancer. Drugs used in chemotherapy, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with cytarabine may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of giving sorafenib together with cytarabine and to see how well it works in treating older patients with acute myeloid leukemia or high-risk myelodysplastic syndrome.
RATIONALE: Baclofen-amitriptyline-ketamine (BAK) gel may lessen peripheral neuropathy caused by chemotherapy. It is not yet known whether BAK gel is more effective than a placebo in treating peripheral neuropathy caused by chemotherapy . PURPOSE: This randomized phase III trial is studying BAK gel to see how well it works compared with a placebo in treating peripheral neuropathy caused by chemotherapy in patients with cancer.
The primary objective of this study is to assess the safety and efficacy of performing unrelated stem cell transplants using intravenous busulfan and fludarabine as preparative therapy and tacrolimus plus methotrexate as the GVHD prophylaxis regimen. The goal is to demonstrate safety, aiming for a transplant related mortality rate (TRM) of < or equal to 40% at 100 days. A TRM of > or equal to 60% will be considered unacceptable. Another goal is to demonstrate efficacy by showing and overall survival of >40% at 1-year following transplant.
