Filter by:Diffuse Large B-cell Lymphoma (DLBCL) is a malignant, aggressive lymphoid cancer. The incidence in Denmark is approximately 450 cases per year. In 2/3 of the cases, complete remission is achieved with immunochemotherapy. The remaining 30% will experience relapse and in 5 % of the patients, this will occur in the central nervous system (CNS). CNS relapse has a very poor prognosis with an overall survival of 3-6 months. In order to identify patients at risk of CNS relapse, the CNS-IPI score is used to stratify the patients into three risk groups according to number of risk factors (low 0-1, middle 2-3 and high risk 4-6 which corresponds to 2-year CNS relapse rates of 0,6%, 3,4% and 10,2% respectively). DLBCL can be subdivided by gene expression analysis into three different types based on the cell of origin (ie the stage of the equivalent normal cell development from which the disease arises): the germinal center B-cell (GCB)-like subtype, the activated B-cell (ABC)-like subtype and unclassifiable. The subdivision is of prognostic importance as patients with GCB-like subtype have a 5-year OS of 76% vs 34% in the non-GCB group. Furthermore, studies have found a higher risk of CNS relapse in the ABC-like subtype compared to the GCB subtype0. Other gene rearrangements of potential importance to the risk of CNS relapse is "double hit" (DHL) (5-10% of newly diagnosed DLBCL patients) and MYC/BCL2 co-expressors (double expressors, DEL). Chemotherapeutic CNS prophylaxis is recommended based on the CNS-IPI stratification for the high-risk group (CNS-IPI 4-5) due to an estimated risk of CNS relapse of 10,2%. However, a relapse risk with a specificity of 10,2% results in almost 90% of the patients potentially receiving 'unnecessary' prophylactic chemotherapy with toxic side effects. One study published on data from the GOYA-trial have integrated COO into the CNS-IPI and found an increased sensitivity with a two year relapse risk of 15,2% in the high risk group. In this study we aim to validate the CNS-IPI and evaluate whether the addition of biomarkers for cell of origin (COO) and double hit (DH) DLBCL improves the prediction of later CNS relapse. This will be done through analysis of patientdata from the Danish nationwide lymphoma database, LYFO, on all patients with DLBCL diagnosed from 1.1.2014 to 1.1.2021 combined with pathology reports from the Danish Pathology registry.
The main objective of the trial is to assess the efficacy and tolerability of Lonca-R in unfit and frail participants with previously untreated DLBCL.
Primary central nervous system diffuse large B cell lymphoma is a rare and aggressive entity of diffuse large B cell lymphoma. A previous transcriptomic study showed an overexpression of TIM-3 and Gal-9 in the tumor microenvironment. The investigators aimed to characterise TIM-3/Gal-9 immune checkpoints by using immunohistochemistry in the tumor microenvironment of primary central nervous system diffuse large B cell lymphoma.
This will be a cohort study of all patients receiving Cluster of Differentiation 19 (CD19)-specific CAR T cell therapy for relapsed/refractory B cell haematological malignancies. Patients will receive cardiac assessment and have serum cardiac biomarkers, ECG, transthoracic echocardiogram and cardiac magnetic resonance imaging performed at baseline prior to CAR T cell therapy, 7 days post CAR T cell infusion, and 3 months post CAR T cell infusion. Abnormalities in these cardiac investigations will be used to demonstrate cardiac injury and identify which patients are most at risk of developing cardiac injury related to CAR T cell therapy.
This retrospective study aimed to investigate the combined prognostic values of intratumoral metabolic heterogeneity (MH), disseminate feature (Dmax) and total metabolic tumor volume (TMTV) by 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography ([18F]FDG PET/CT), and establish novel nomograms to improve prognosis prediction in diffuse large B-cell lymphoma (DLBCL)
This study enrolled patients with relapsed or refractory diffuse large B cell lymphoma treated with polatuzumab vedotin-based chemoimmunotherapies. Patients were allowed to use chemotherapy regimens other than Rituximab and Bendamustine and transplantation following polatuzumab vedotin was also allowed.
Background: Burkitt Lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) are aggressive B cell lymphomas. Frontline treatment does not always work. Researchers want to see if a combination of drugs can help. Objective: To learn if it is safe to give people with certain cancers copanlisib together with rituximab and combination chemotherapy (DA-EPOCH-R). Eligibility: People ages 18 and older with relapsed and/or refractory highly aggressive B-cell lymphomas such as BL and certain types of DLBCL. Design: Participants will be screened with: Medical history Physical exam Bone marrow aspiration and biopsy. A needle will be put into their hipbone. Marrow will be removed. Imaging scans of the chest, abdomen, pelvis, and/or brain Tumor biopsy (if needed) Blood and urine tests Heart function tests Treatment will be given in 21-day cycles for up to 6 cycles. Participants will get copanlisib by intravenous (IV) infusion. They will also get a group of medicines called DA-EPOCH-R, as follows. They will get rituximab by IV infusion. Doxorubicin, etoposide, and vincristine will be mixed together in an IV bag and given by continuous IV infusion over 4 days. They will get cyclophosphamide by IV infusion. They will take prednisone by mouth. Participants will have frequent study visits. At these visits, they will repeat some screening tests. They may give tissue, saliva, and cheek swab samples. They will have at least one spinal tap. For this, a needle will be inserted into the spinal canal. Fluid will be removed. Participants will have a visit 30 days after treatment ends. They will have follow-up visits for at least 5 years.
The RTXM83-AC-01-11 study evaluated efficacy and safety outcomes in relation to the use of Vivaxxia during 6 treatment cycles (at the investigator's discretion, up to 8 treatment cycles could be administered), followed by 9 months of follow-up. , this follow-up time being sufficient for the analysis of non-inferiority in relation to the reference medicine. However, data on late events of efficacy and safety are of great value to contribute to a robust clinical response and to strengthen confidence in the use of biosimilar medicines. For this reason, Libbs Farmacêutica proposes this retrospective observational study to collect data on late outcomes of the pivotal study that directed the approval of the biosimilar rituximab (Vivaxxia) from the research participants from Brazil. The present retrospective observational study LB2002 will sub-analyze selected results of efficacy and safety from study RTXM83-AC-01-11 in participants over 18 years of age randomized in Brazil, totaling 28 participants, in addition to evaluating late efficacy and safety outcomes. Information on subsequent treatment / protocol should also be collected for participants who have progressive or recurrent disease, instituted by research centers under these conditions. The proposal is to compare descriptively the selected outcomes of efficacy and safety of these participants with the same outcomes selected for the global population in the RTXM83-AC-01-11 study, and also provide late safety and effective data important for anti-neoplastic processes.
The development of new diagnostic tools and targeted therapy have significantly improved the management of non-Hodgkin's malignant lymphomas and thus their long-term prognosis. However, in the study of improved patient management, survival is not the only measurable indicator and preservation of quality of life is an essential component. In addition, there is little existing data regarding the determinants of quality of life in patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) in the general population in France.
This prospective observational study aims to evaluate the robustness and persistence of immune responses to vaccination, define factors associated with impaired immune responses and assess the incidence of COVID-19 infections in vaccinated individuals. To do this, we will collect peripheral blood from patients with lymphoid cancers before and after their COVID-19 vaccination. The blood will be explored in the laboratory for antibodies to SARS-CoV-2 and T-cell responses to the spike protein. Detailed clinical information will also be collated on about their cancer and treatment.
