Active clinical trials for "Lymphoma"

The purpose of this study is to determine whether combined chemotherapy [rituximab plus high dosage methotrexate, lomustine, and procarbazine] followed by maintenance therapy with procarbazine is effective in the treatment of cerebral Non Hodgkin lymphoma [PCNSL] in patients > 65 years.

The purpose of this study is to evaluate the efficacy (and safety) of the following treatment squeme:Ciclophosphamide, Vincristine, lyposomal Doxorrubicine (Myocet) and Prednisone,combined with Rituximab in first line treatment for patients with aggresive No Hodgkin B lymphoma and cardiovascular risk

RATIONALE: Studying a diagnostic biomarker test in blood samples from patients who have undergone a donor stem cell transplant for cancer may help doctors plan treatment. PURPOSE: This clinical trial is studying an immunologic diagnostic blood test to see how well it works in predicting side-effects in patients with hematologic cancer or other disorders who have undergone a donor stem cell transplant.

All patients are treated according to the same therapy regimen. Therapy duration (number of cycles) and radiotherapy vary according to age group, stage and response. Chemotherapy consists of a pre-phase-treatment (for all patients) and varying A, B and C cycles. Therapy for Patients in the 18-55 Age Group Patients in stages III-IV and all patients with mediastinal tumors or extranodal involvement are administered 6 cycles (A1, B1, A2, B2, A3, B3). Chemotherapy is stopped after 4 cycles (A1, B1, A2, B2) for patients with stage I/ II if a clear CR has been achieved and there is initially no mediastinal or extranodal involvement. In cases of refractory or progressive disease after 4 cycles, study therapy is stopped. These patients are to be given salvage therapy with subsequent stem cell transplantation. Therapy for Patients older than 55 years The course corresponds to that of patients in the younger age group, but the regimen is dose reduced (A1*, B1*,A2*, B2*, A3*, B3*). Antibody therapy with anti-CD20 is to be administered on day 1 of each chemotherapy cycle (A, B). After end of chemotherapy (6 or 4 cycles) 2 more cycles of anti-CD 20 are to be administered to reach a total number of 8 resp. 6 cycles antibody therapy.

This prospective trial will assess the activity and feasibility of a new high-dose methotrexate-based high-dose sequential chemotherapy combination in patients with B-cell lymphomas and CNS involvement at diagnosis or relapse. Selected drugs, with a well-documented anti-lymphoma activity, will be administered at high doses to increase blood-brain barrier penetration and CNS bioavailability as well as to reduce potential cross-resistance.

The primary objective of this study is to evaluate the efficacy of Fludarabine, Adriamycin and Dexamethasone (FAD) as first line therapy in patients with Peripheral T-cell lymphomas (PTCL). 30 patients will be treated into this study.

The purpose of this study is to evaluate the efficacy and safety of combination chemotherapy with etoposide, methylprednisolone, high-dose cytarabine and oxaliplatin (ESHAOx) for patients with refractory or relapsed Hodgkin's lymphoma (HL).

The purpose of this study is to determine whether R-FC is more beneficial that R-CVP in the treatment of older patients (aged 60 or over) with Follicular Lymphoma (FL).

Nowadays, therapy with monoclonal antibodies is considered to be a standard treatment that increases the rate of remissions and the overall survival in patients with follicular lymphoma. Nevertheless there are an important number of patients who do not benefit from this therapy. A way to improve the efficiency of monoclonal antibodies therapy could be to improve the activity of the effector arm of the immune system. A strategy that has been proposed to obtain this improvement is the utilization of lymphocyte activated killer (LAK) cells. In addition, the combination of LAK cells with monoclonal antibodies might obtain an additive effect across the stimulation of the antibody dependent cellular cytotoxicity (ADCC)activity. The present clinical assay proposes to study the feasibility, safety and effectiveness of treatment with autologous effector cells expanded ex vivo associated with a standard maintenance treatment with rituximab in patients with follicular lymphoma in remission after first-line treatment. In addition, we plan to analyse various biological parameters that can predict the susceptibility of patients to treatment with rituximab. Specifically, we propose to study the polymorphisms of Fc receptor, polymorphisms related to the ability of complement activation, to study both the complement activity and peripheral blood cell subpopulations that can mediate directly or indirectly dependent antibody cytotoxic effect. We will also try to correlate any of these biological parameters with the response to treatment.

Poor prognosis dufuse large B-cell lymphoma (DLBCL) represents 50% of all DLBCL with overall cure rates ranging from 50-60% with modern dose-dense immunochemotherapy regimens such as R-CHOP14. Using an alternative strategy, as infusional and dose-adjusted R-EPOCH, the investigators have shown an 83% of complete responses (CR), with an estimated 5-year overall survival (OS) rate of 75% (García-Suárez et al. British Journal of Haematology 2007, 136:276). Despite this improvement in outcome, the search for new treatment strategies should continue. Therefore, compared with prior R-EPOCH the investigators decided to investigate whether the introduction of dexamethasone (40 mg IV on days 1-5) in place of prednisone (based upon data which demonstrated that the former was associated with enhanced Central Nervious System penetration) and the reduction of treatment intervals from 3 to 2 weeks would be feasible and might improve the outcome in this group of patients.
