Active clinical trials for "Lymphoma"

Comparison of cumulative incidence of CNS relapses in patients with diffuse large B-cell lymphoma with intermediate or high risk of CNS relapse treated with CNS prophylaxis: either with 2 doses of intravenous methotrexate 3g/m2 i.v.(arm A) or 6 doses of intrathecal methotrexate 12mg (arm B) and in patients with low risk of CNS relapse without CNS prophylaxis (arm C).

The primary purpose of the study is to quantify participants' demographic parameters, country standard therapies, treatment patterns and outcomes among participants with chronic lymphocytic leukemia (CLL), multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL) in oncology concentration hospitals in Latin America.

The trial will enroll 194 previously untreated DLBCL patients over 20 months, with the objective to send to the local investigator an extensive molecular tumor characterization by D38 in at least 80% of enrolled patients. The feasibility and efficiency will be demonstrated by deploying and operating a nation-wide network of dedicated multidisciplinary platforms.

The purpose of this study is to test resting state functional Magnetic Resonance Imaging (rsfMRI) scans to see if rsfMRI scans are better than the standard task based fMRI scans at diagnosing or monitoring central nervous system lymphoma.

patients with refractory /relapsed lymphoma received high-dose etoposide for hematopoietic stem cell (HSC) mobilization.All patients received high-dose etoposide 20-25 mg/kg/d intravenously for two consecutive days followed by rhG-CSF10ug/kg/day subcutaneously at 48 hours after chemotherapy; rhG-CSF was continued until the end of harvesting for HSCs/HPCs. Peripheral blood counts were performed daily for all patients following the initiating of rhG-CSF. Leukapheresis was performed when peripheral blood white blood count exceeded 4×109/L with blood cell The harvested cells reached at least 2*108/kg for mononuclear cells and/or 2*106/kg for CD34+ cells with once to twice leukapheresis. The final product was kept frozen in liquid nitrogen.Auto-PBSCT

This research study is collecting and storing samples of bone marrow and blood from patients with relapsed acute lymphoblastic leukemia or relapsed non-Hodgkin lymphoma. Collecting and storing samples of bone marrow and blood from patients with cancer to study in the laboratory may help doctors learn more about cancer and help predict the recurrence of cancer.

The purpose of the study is to assess in a prospective series of patients with high tumor burden follicular lymphoma treated with R-CHOP, the predictive value of [18F]-FDG PET performed over (after 4 treatments), and at the end of the first-line treatment on progression-free survival at 2 years.

High dose methotrexate (MTX) is responsible of severe toxicity in patients in whom elimination from plasma is delayed. Factors responsible for MTX accumulation are partly known but some patients still experience toxicity despite adequate measures being taken. Our hypothesis is that renal tubular secretion may be impaired in these patients. This study aims at evaluating the performance of the UCP ratio (urinary ratio of coproporphyrins), a putative biomarker of tubular secretion, in predicting delayed MTX elimination.

There has been considerable international /national interest in the GEM-P regimen for treatment of patients with relapsed/refractory lymphoma. Currently, there is no accepted standard therapy for these patients. Since the publication of our experience with this regimen (Study with CCR ethics number 1857 closed to recruitment in July 2003:Ng M, Waters J, Cunningham D et al, Br J Cancer 2005;92:1352-7), we have treated relapsed/refractory lymphoma patients with this regimen and would like to undertake a retrospective review of a sub-group of these patients with diffuse large B cell lymphoma (DLBCL). Patients treated with GEM-P with or without Rituximab prior to March 2005 for refractory/relapsed DLBCL will be included in the analysis. Accrual of eligible patients currently under follow-up will be performed in clinic at the time of next appointment. All patients accrued will give informed consent for retrospective case note review, after discussion with a study investigator and after receiving a study information sheet. All eligible patients identified from the pharmacy database, and will be consented at the time of the next clinic appointment, if they are agreeable for the retrospective case note review.

This protocol is designed to evaluate children with cancer who appear to be probable candidates for future protocol entry or have disease manifestations that are of unique scientific importance or educational value.
