Tumor Heterogeneity in Diffuse Large B-cell Lymphoma in Relation to CNS Involvement and Cell-free...
LymphomaLarge B-Cell1 moreThe aim of the project is to clarify whether DLBCL exhibits mutational diversity among different lymph node tumors in one and the same patient. It is desired to find out whether a possible difference between lymph node tumors / tumors can explain why patients who initially (at diagnosis) have the same prognosis, sometimes have a completely different course, eg with rapid recurrence of the disease after treatment. A possible difference could also perhaps shed light on why disease in specific places spreads more frequently to the brain - and therefore have an impact on when one chooses to give preventive treatment against spread to the brain. Monitoring of circulating cell-free DNA (ctDNA) is a new, potential, non-invasive tool for measuring the full spectrum of genetic variations / mutations and is to be investigated in our study as a possible non-invasive assessment of diversity / heterogeneity.

Early On-therapy PET at First-line Treatment in Diffuse Large B-cell Lymphoma Stage IIB-IV
Diffuse Large-Cell LymphomaEarly identification of refractory lymphoma patients provides a basis for stratification between responders to standard approaches and non-responders who may benefit from an early change to an alternative treatment strategy.Metabolic or molecular imaging with fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG-PET) has emerged as a powerful imaging modality for diagnosis, staging, and therapy monitoring of a variety of cancers. The primary hypothesis of the present study is that early response can be pinpointed by PET reflecting both tumor burden and activity, as a surrogate for final outcome. An increasing number of studies have suggested the potential role of 18F-FDG PET in the staging and monitoring of lymphomas. The optimal timing of PET scans and the potential role of quantitative PET using SUV to assess response to chemotherapy remain to be defined. Confirmation of very early 18F-FDG-PET as a significant predictor of treatment response in a homogenous group of aggressive lymphoma patients would potentially change the prognosis of the patient by allowing earlier use of alternative therapies and discontinuation of therapy that will not lead to a significant tumour response.
FLT-PET/CT vs FDG-PET/CT for Therapy Monitoring of Diffuse Large B-cell Lymphoma
LymphomaLymphoma2 moreA research study of a new method of visualizing internal organs called 18F-FLT PET/CT that yields better tracking of cancer treatment progress. PET/CT stands for positron emission tomography with low dose computed tomography and has been used for many years. 18F-FLT PET/CT uses a new tracer, fluorothymidine, which is taken up by cells that are actively proliferating or dividing such as cancer cells. We hope to learn whether this tracer is superior to the conventional tracer for monitoring treatment of diffuse large B-cell lymphoma (DLBCL).

Follow-up Study of SyB L-0501 in Combination With Rituximab to Treat DLBCL
Diffuse Large B Cell LymphomaThis study is a follow-up study to update the survival time data (overall survival, progression-free survival, and duration of response) of the subjects who received SyB L-0501 at least once in Phase III Study of SyB L-0501 in combination with rituximab to treat recurrent/relapsed diffuse large B-cell lymphoma study (2017002) by reviewing their follow-up information following the study completion of Study 2017002. In this study, the follow-up information gathered until the end of the investigation period is reviewed after obtaining informed consent from the subjects or their legal representatives. Accordingly, no intervention, such as administration of the investigational product or examination, will be performed. Investigative methods The investigator or subinvestigator gives an explanation to a subject or his/her legal representative to obtain written informed consent to provision of information pertaining to this study. After obtaining informed consent, the investigator or subinvestigator reviews the follow-up information following the completion of Study 2017002 in source documents regarding the following items: 1. Survival status 2. Aggravation (progression or recurrence) 3. Drugs or procedures used for treatment of DLBCL or prophylaxis against its progression or recurrence 4. Occurrence of other malignant tumors
DLBCL Treatment in Children and Adolescents
Diffuse Large B-cell LymphomaWe compared the efficacy and safety of modified NHL-BFM-90 regimen and R-CHOP/CHOP regimen in pediatric (aged 0-14 years) and adolescent(aged 15-18 years)DLBCL patients in a single institution during a 20-year period. we compared the efficacy and safety of modified NHL-BFM-90 regimen and R-CHOP/CHOP regimen in pediatric (aged 0-14 years) and adolescent(aged 15-18 years)DLBCL patients in a single institution during a 20-year period. To our best knowledge, no reports have been previously published regarding the comparison.
Use of a Patient Preferences Shared Decision-Making Encounter Tool in Clinical Practice for Patients...
Diffuse Large B Cell LymphomaFollicular LymphomaThe goal of this project is to test the feasibility of a Patient Preferences in Shared Decision-Making encounter tool (PPSDM) in the clinical context of Diffuse Large B-Cell Lymphoma (DLBCL) and Follicular Lymphoma (FL). This project will evaluate the feasibility of a shared decision-making (SDM) model that employs an "encounter tool"1 to facilitate SDM at the point of a treatment decision for patients with DLBCL and FL.
Study for Late Assessment of the Safety and Efficacy of Biosimilar Rituximab
Diffuse Large B Cell LymphomaThe 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.
