Active clinical trials for "Lymphoma, B-Cell"

This study will evaluate IgNGS at different time points in newly diagnosed DLBCL patients homogeneously treated (RCHOP) to address its correlation with conventional techniques (i.e., positron emission tomography/computed tomography imaging (PET/CT) and outcome.

Describe the treatment of B-cell non-Hodgkin lymphoma patients who receive lenalidomide single drug or lenalidomide combined with rituximab (with or without other drugs), and evaluate the efficacy and safety of lenalidomide single drug or lenalidomide combined with rituximab (with or without other drugs) in the real-world setting.

To assess the clinical outcomes following treatment with Pola in combination with Bendamustine, Rituximab (BR) or Rituximab (R) in patients with R/R DLBCL who are not eligible for transplantation in the real-world setting.

RATIONALE: Treatment for diffuse large B-cell non-Hodgkin's lymphoma may cause side effects and secondary cancers later in life. An observational study that evaluates patients after undergoing six courses of combination chemotherapy with or without rituximab and radiation therapy may help doctors predict a patient's response to this treatment and help plan the best treatment. PURPOSE: This observational study is evaluating patients with diffuse large B-cell non-Hodgkin's lymphoma to see how well treatment on clinical trial CAN-NCIC-LY9 works.

The purpose of this study is to invite all people diagnosed with cancer who meet the eligibility criteria to complete questionnaires before their treatment begins and at regular intervals over time to assess the impact of cancer and its treatment on people's lives in the short, medium and long term. We will explore a range of factors to determine their role in both recovery of health and well-being and self-management. Although it is known that people who have had cancer are likely to experience a number of physical and psychological problems as a result of the disease and treatment, it is not known what the 'typical' course of recovery of health and well-being looks like, how long it takes and how this can be influenced. We will determine pathways to recovery of health and well-being following cancer diagnosis (initially breast cancer diagnosed <50 years, Non-Hodgkin Lymphoma and gynaecological cancers) and identify what factors influence this. This includes assessing the relative importance of the person's illness, personal attributes, perceived burden of treatment, role of the environment they live in, including health / social care and personal networks of support, and their ability and capacity to self-manage. We will identify who is most at risk of problems and what environmental supports and resources people are able to mobilise to support their self-management. We will also explore who has the confidence and ability to manage during and beyond treatment and what factors influence this and whether this leads to earlier problem resolution and restoration of health and well-being. This knowledge will be used to develop and test future supportive interventions to enhance the rapid recovery of health and well-being - our long term aim being to design ways of helping people with cancer in areas we identify as problematic for them.

MiRNAs are small (~19-25 nucleotides) non-coding RNA molecules that bind to mRNA in a sequence-specific manner. MiRNAs regulate gene expression at the post-transcriptional level. MiRNAs regulate critical cell processes such as metabolism, apoptosis, development, cell cycle, hematopoietic differentiation and have been implicated in the development and progression of several types of cancers, including hematological malignancies. Over-expression, amplification and/or deletion of miRNAs and miRNA-mediated modification of epigenetic silencing can all lead to oncogenic pathways. Hematologic cancers, which are caused by the malignant transformation of bone marrow cells and the lymphatic system, are usually divided into three major clusters: leukemia, lymphoma, and multiple myeloma. To date, some of the hematological malignancies are very aggressive that early diagnosis is essential for improving prognosis and increasing survival rates. However, current diagnostic methods have various limitations, such as insufficient sensitivity, specificity, it is also time-consuming, costly, and requires a high level of expertise, which limits its application in clinical contexts. Thus, development of new biomarkers for the early detection and relapse of hematological malignancies is desirable. Some of the innate properties of miRNAs make them highly attractive as potential biomarkers. MiRNAs can be readily detected in small volume samples using specific and sensitive quantitative real-time PCR; they have been isolated from most body fluids, including serum, plasma, urine, saliva, tears and semen and are known to circulate in a highly stable, cell-free form. They are highly conserved between species, allowing the use of animal models of disease for pre-clinical studies. Furthermore, tumor cells have been shown to release miRNAs into the circulation and profiles of miRNAs are altered in the plasma and/or serum of patients with cancer. A growing number of publications confirm that miRNAs can be a useful biomarker for hematological malignancies diagnosis and progression.

This study is to evaluate the efficacy related molecular biomarker of Lenalidomide plus RCHOP or RICE in the treatment of de novo or Refractory and Relapsed DLBCL patients

This is a prospective , open, multicenter, randomized phase Ⅲ study. The investigators planed to include 732 untreated CD20 positive diffused large B cell lymphoma adults,to random to R-CHOP21, CHOP14 , R-CHOP14 regimen groups after signature the informed consents. The patients will receive safety assessment every cycles, and efficacy evaluation every 2 cycles. Every-two-months follow up will be received after finishing the treatment.

This is an observational cohort study of patients with a new diagnosis of B cell Chronic Lymphocytic Leukemia or B cell Non-Hodgkin's Lymphoma who will receive an anti-CD20 monoclonal antibody treatment during the induction phase of their treatment. Throughout the study, patients will have four blood draws at specified time points throughout the study. The initial blood draw will be analysed test patients for Cytomegalovirus and conduct a g-NK cell analysis. The final three blood draws will be conducted to analyse the g-NK cells at specified time points. The objectives of this study are to: 1) characterize the frequency of CMV (+) and g-NK (+) individuals in the B-NHL and B-CLL populations, 2) Determine changes in circulating g-NK cells during and after anti-CD20 monoclonal antibody containing remission induction chemotherapy and 3) Evaluate whether the presence of g-NK cells improve the outcome of anti-CD20 monoclonal antibody containing remission induction treatment of patients with B-NHL or B-CLL.

The purpose of this study is to determine whether the CD16- monocyte/CD16+ monocyte ratio could help predict the prognosis of DLBCL and PTCL.
