Mixed Molecular Clinical Index (MMCI) in Diffuse Large B-cell Lymphoma (DLBCL)

Diffuse Large B Cell Lymphoma

This is a prospective observational study. The primary objective is to identify new prognostic biomarkers for DLBCL patients in terms of progression-free survival (PFS) and able to add predictive capacity to recognized important clinical factors. The secondary objectives are: to identify new biomarkers associated with overall survival (OS) and objective response rate (ORR) to characterize tissue and circulating immune microenvironment of DLBCL patients by bulk and single cell transcriptomics; to assess the correlation between the expression of immune checkpoint genes and mRNA signature; to describe the mutational status of a panel of genes relevant to DLBCL pathogenesis;. to assess the correlation between protein expression, mutational status and the messenger RNA (mRNA) signature. For each enrolled patient, immunohistochemical determinations will be performed: Cell of origin (COO) (Germinal Cell -GC- or activated B-cell - ABC- type according with Hans algorithm ), evaluation of cluster of differentiation antigen 20 (CD20), cluster of differentiation antigen 5 (CD5), cluster of differentiation antigen 10 (CD10), Bcl6, Bcl2 (cut off>50%), Multiple Myeloma 1 / Interferon Regulatory Factor 4 protein (MUM1/IRF4), c-myc (cut off>40%) and Ki67, fluorescence in situ hybridization (FISH) for c-myc and if rearranged, for Bcl2 e Bcl6 ). Moreover, paraffin embedded (FFPE) tumor specimens will be collected for RNA extraction and mRNA expression analysis and sent to Bioscience Laboratory of Istituto Scientifico Romagnolo per lo studio e la cura dei tumori (IRST-IRCCS).

Observation in Patients With Diffuse Large B-Cell Non-Hodgkin's Lymphoma Treated on Clinical Trial...

Long-term Effects Secondary to Cancer Therapy in AdultsLymphoma

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.

HORIZONS: Understanding the Impact of Cancer Diagnosis and Treatment on Everyday Life

Breast Cancer FemaleBreast Neoplasm18 more

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.

Identification of Hematological Malignancies and Therapy Predication Using microRNAs as a Diagnostic...

LymphomaB-Cell3 more

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.

B Cell Lymphocytic LeukemiaB Cell Non-Hodgkin's Lymphoma

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.
