Active clinical trials for "Lymphoma"

The purpose of this study is to differentiate Kikuchi's disease and malignant lymphoma by soft tissue ultrasound.

The purpose of the study is to create a prospective database of T-Lymphoblastic Lymphoma (T-LBL) cases in order to conduct an appropriate statistical study as well as to monitor diagnosis and minimal residual disease (MRD), to detect specific genetic profile useful to give advices on therapies, to assess if PET has a prognostic validity on T-Lymphoblastic Lymphoma (T-LBL).

To establish a pathology reference laboratory for the consultation on the diagnosis of infectious diseases and lymphoma. To study the specific pathogens on 100 cases of unexplained death due to infectious diseases in the files of Taiwan CDC and the Forensic Institutes of Department of Law and Justice. To study the distribution of children lymphoid lesions in Vietnam and Taiwan and their virus association. To establish a tissue bank for infectious diseases and lymphoma.

The goal of this study is to determine the feasibility of the diffusion weighted Magnetic Resonance Imaging in the evaluation of the treatment response in patients with malignant lymphoma. The investigator's objective is to compare the changes of mean Apparent Diffusion Coefficient value of the tumor with the changes of maximum Standardized Uptake Value of the tumor in positron Emission Tomography Computed Tomography in both pre and post therapy status .

This study with retrospective data collection does not entail sample size calculation. The study will involve patients who received bendamustine + rituximab for relapsed/refractory mantle cell lymphoma and meet the inclusion/exclusion criteria at each participating study site. Considering the incidence of mantle cell lymphoma in Korea and the number of participating sites, the expected sample size is approximately 40.

Collecting data about the rare leukemic presentation of anaplastic lymphoma to study the characteristics of patients with leukemic phase of ALCL

To assess specificity and overall accuracy of interim dual-point acquisition PET in predicting treatment outcome. The study is aimed at assessing the specificity of interim dual-point PET performed after 2 ABVD cycles to predict treatment outcome in early-stage Hodgkin's Lymphoma patients presenting bulky lesions at baseline.

MERIT-NHL as an addendum to the International Registry of Radioimmunotherapy (RIT registry) pooling clinical data of patients who suffered from a non-Hodgkin´s lymphoma also includes the documentation of the respective FDG-PET and CT-image files in an online archive. Based on these documented clinical and imaging data, the MERIT study group centrally performs an intra- as well as interindividual evaluation of follicular CD20+ lymphoma lesions before and after radioimmunotherapy. According to this, the aim of the MERIT-NHL study is to prospectively identify yet unknown patient- and lesion specific prognostic factors predicting patient´s outcome in line with the therapeutic modality radioimmunotherapy.

Although interim 18F-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET)/computerized tomography (CT) scan has emerged as a powerful prognostic tool in predicting treatment outcome in Hodgkin's lymphoma (HL) and diffuse large B cell lymphoma (DLBCL), the positive predictive value (PPV) of interim PET/CT scanning has not been determined in patients with peripheral T cell lymphoma (PTCL). The sequential interim PET/CT will be prospectively investigated to determine whether it provided additional prognostic information and could be a positive predictable value for the treatment of PTCL.

Non-Hodgkin lymphoma (NHL) is one of the more frequent cancers in the western world with approx. 800 new cases annually in Denmark. Diffuse large B-cell lymphoma (DLBCL) in Denmark accounts for almost 40% of newly diagnosed NHL cases. Treatment with the combination of chemotherapy and monoclonal antibodies has significantly improved prognosis over the past decade, but a large proportion of patients with DLBCL will continue to relapse with our current treatment options. Therefore, there is a need for reliable methods for detection of treatment response as early as possible in the treatment course in order to identify patients who respond poorly to standard treatment and potentially would benefit from a change in treatment strategy. This has still not been established, but a valid early marker is required in order to allow randomized trials of treatment stratified by early response. One of the most promising applications of PET is the metabolic assessment of the early response of cancer treatment. This study is a national prospective multicenter study emanating from the Danish Lymphoma Group (DLG). Patients are scanned after each of the early 4 cycles of chemo therapy. The aim is to establish the correct timing of response evaluation. Additionally, the investigators wish to investigate the optimal qualitative and quantitative method of response assessment in order to predict post-therapeutic remission and long-term prognosis.This study will contribute to interim-PET being implemented in the most optimal way in daily clinical practice.
