Filter by:Patients with previously untreated diffuse large B-cell lymphoma will receive standard treatment with R-CHOP (rituximab,cyclosphosphamide, doxorubicin, vincristine, and prednison) for 6 cycles, cycle length is 14 or 21 days. In addition, valproate is given three times daily day 1-3 in escalated doses. The rationale for adding valproate to standard treatment is invitro data indicating a sensitizing effect to chemotherapy, and an increase in CD 20-expression. Patients are included in 3+3 cohorts with escalation of valproate dose, planned dos levels are 30, 60, 80, 100, 120, 140 mg/kg/day. A total of 20 patients will be treated at the MTD.
The investigators perform a retrospective microarray gene expression profiling study of FFPE from a cohort of DLBCL patients with whole genome cDNA mediated Annealing Selection and Ligation (WG-DASL) assay. The investigators also study the pattern of microRNA from patients with diffuse large B-cell lymphoma. The results of gene expression profiles and microRNA is correlated with clinical outcomes of diffuse large B-cell lymphoma.
Primary mediastinal large B cell lymphoma is treated with a combination of chemotherapy and the monoclonal antibody rituximab (chemoimmunotherapy). Following chemoimmunotherapy patients receive radiation therapy if they have residues which may be active tumour. However at the end of chemoimmunotherapy the majority of patients show tissue scarring that is not necessarily active tumor. In recent years, PET/CT has proved to be a good tool to accurately identify active tumor from scar tissue in patients treated for mediastinal lymphoma.The purpose of this trial is to test whether radiation therapy is really necessary in patients where PET/CT has shown that the tumor is no longer active. Therefore we will compare radiation treatment with careful observation. Patients that at the end of conventional treatment of chemoimmunotherapy have a negative PET/CT (i.e., without residues suspected to contain active tumor), will randomly assigned to two different treatment groups: one treatment group will receive the radiation treatment, and the other treatment group will receive careful observation. The trial is planned according to a non-inferiority design aimed at demonstrating that progression free survival after the experimental treatment (observation) is not worse than after the standard comparator (mediastinal irradiation.Participation in this study could spare patients with complete remission at the end of chemo immunotherapy (PET/CT negative) radiation therapy that may be unnecessary.
This randomized phase II/III trial studies how well combination chemotherapy with or without rituximab works in treating younger patients with stage III-IV non-Hodgkin lymphoma or B-cell acute leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibody, such as rituximab, may block cancer growth in different ways by targeting certain cells. It is not yet known whether combination chemotherapy together with rituximab is more effective in treating patients with non-Hodgkin lymphoma or B-cell acute leukemia.
Background: - Although progress has been made in treating children with B-cell cancers such as leukemia or lymphoma, many children do not respond to the standard treatments. One possible treatment involves collecting white blood cells called T cells from the person with cancer and modifying the cells to attack the B-cell cancer. The cells can then be given back to the participant. This study will use T cells that have been modified to attack the cluster of differentiation 19 (CD19) protein, which is found on the surface of some B-cell cancers. Objectives: - To see if anti-CD19 modified white blood cells are a safe and effective treatment for children and young adults with advanced B-cell cancer. Eligibility: - Children and young adults between 1 and 30 years of age who have B-cell cancer (leukemia or lymphoma) that has not responded to standard treatments. - The leukemia or the lymphoma must have the CD19 protein. - There must be adequate organ function. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies or bone marrow biopsies may be performed depending on the type of cancer. - Participants will undergo a process where white blood cells are collected, called apheresis. These cells will be modified to contain the anti-CD19 gene. - Participants will have 3 days of chemotherapy to prepare their immune system to accept the modified cells. - Participants will receive an infusion of their own modified white blood cells. They will remain in the hospital until they have recovered from the treatment. - Participants will have frequent follow-up visits to monitor the outcome of the treatment. - If the participant benefits from the treatment, then he/she may have the option for another round of treatment.
This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.
This study is to determine first the appropriate dose of lenalidomide to administer in combination with fixed doses of obinutuzumab in relapsed/refractory follicular lymphoma patients. In a second step, this study aims to determine the efficacy of this combination in 3 separate populations: relapsed/refractory aggressive lymphoma (diffuse large B-cell lymphoma and mantle cell lymphoma: cohort 1), relapsed/refractory follicular lymphoma (cohort 2) and previously untreated follicular lymphoma (cohorts 3 and 4).
The purpose of this study is to identify if, and at what dose, ibrutinib may be administered with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and to document responses of this combination in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).
This phase I trial studies the side effects and the best dose of alisertib when given together with vorinostat in treating patients with Hodgkin lymphoma, B-cell non-Hodgkin lymphoma, or peripheral T-cell lymphoma that has come back. Alisertib and vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors find better ways to treat cancer. PURPOSE: This research trial studies genes in samples from patients with limited and advanced diffuse large B-cell lymphoma.
