CNS Prophylaxis in Diffuse Large B-cell Lymphoma

Diffuse Large B-cell Lymphoma

Comparison of cumulative incidence of CNS relapses in patients with diffuse large B-cell lymphoma with intermediate or high risk of CNS relapse treated with CNS prophylaxis: either with 2 doses of intravenous methotrexate 3g/m2 i.v.(arm A) or 6 doses of intrathecal methotrexate 12mg (arm B) and in patients with low risk of CNS relapse without CNS prophylaxis (arm C).

Real Time Molecular Characterization of Diffuse Large B Cell Lymphoma (DLBCL)

Diffuse Large B Cell Lymphoma

The trial will enroll 194 previously untreated DLBCL patients over 20 months, with the objective to send to the local investigator an extensive molecular tumor characterization by D38 in at least 80% of enrolled patients. The feasibility and efficiency will be demonstrated by deploying and operating a nation-wide network of dedicated multidisciplinary platforms.

Coproporphyrine Isomers and Methotrexate Elimination

Central Nervous System NeoplasmsLymphoma4 more

High dose methotrexate (MTX) is responsible of severe toxicity in patients in whom elimination from plasma is delayed. Factors responsible for MTX accumulation are partly known but some patients still experience toxicity despite adequate measures being taken. Our hypothesis is that renal tubular secretion may be impaired in these patients. This study aims at evaluating the performance of the UCP ratio (urinary ratio of coproporphyrins), a putative biomarker of tubular secretion, in predicting delayed MTX elimination.

Real-world Resource Use and Costs of CAR-T Therapies in Diffuse Large B-cell Lymphoma (DLBCL)

Diffuse Large B-cell Lymphoma (DLBCL)

A retrospective, non-interventional cohort study was used to address the study objectives. This study aimed to provide a better understanding of real-world healthcare resource utilization (HRU) and healthcare reimbursement costs associated with CAR-T therapy among patients with r/r Diffuse Large B-cell Lymphoma (DLBCL).

Utility Study in Diffuse Large B-Cell Lymphoma (DLBCL)

Diffuse Large B-Cell Lymphoma

This study is a prospective, cross-sectional survey to be administered to real patients in remission from DLBCL using a 15-minute postal or online survey. The project is designed to describe the impact of DLBCL remission on health utility and quality of life. Data collection will occur over a 4-month period.

BMS_PD-L1_onco : Assessment of the PD-L1 Protein as a Biomarker in Oncology and Hematology

Diffuse Large B-cell LymphomaHodgkin Lymphoma2 more

Diffuse large B-cell lymphomas (DLBCLs) represent 25 to 30% of adult non-Hodgkin lymphomas in western countries. DLBCLs are aggressive cancer but potentially curable with multi-agent chemotherapy. Whereas R-CHOP regimen has led to a marked improvement in survival, this disease remains a biologically heterogeneous entity. New therapeutic strategies are required including identification of patients' subgroups with different prognostic. This project is based on BMS_LyTrans and Goelams 075 clinical trial. A study of whole blood transcriptome in 75 DLBCL patients and in 87 controls showed that PD-L1 (CD274) gene was overexpressed in DLBCL patients. Preliminary results demonstrated that PD-L1 is detected in plasma of DLBCL patients with a significantly higher concentration than in controls. This protein was selected as a potential biomarker because of its established role in anti-tumoral immunity. Interaction between PD-L1 and its receptor PD-1 is known to inhibit activation of immune responses by inducing T-lymphocytes anergy and/or apoptosis. Moreover, a direct involvement of PD-L1 in the protection of cancer cells from lysis by activated T lymphocytes has been demonstrated. PD-L1 expression has been described in several solid tumours, including ovary cancer, breast cancer, colon cancer, renal cell carcinoma, non-small cell lung carcinoma and in hematological malignancies such as T-NHL, MM and Hodgkin's lymphoma. Furthermore the expression of PD-L1 by tumour cells is associated with poor prognosis. The blockade of PD-L1/PD-1 axis may represent a novel therapeutic approach in aggressive cancers. These first results incite to identify the cells releasing soluble PD-L1 and to investigate its role in the anti-tumoral immunity in DLBCL patients. The aim of this study is to identify cells producing soluble PD-L1 in DLBCL patients at diagnosis in comparison to others tumours known to express PD-L1 (metastatic breast cancer, Hodgkin's lymphoma, non-small cell lung cancer).

Multicenter Prospective Registry Study of Diffuse Large B Cell Lymphoma

Diffuse Large B Cell LymphomaNeutropenia1 more

This study was designed to review clincal outcomes of Diffuse Large B Cell Lymphoma (DLBCL) treated with R-CHOP chemotherapy in the era of pegylated-filgrastim. The investigators will prospectively collect clinical data and treatment outcome of patients with DLBCL who use prophylactic pegylated-filgrastim.

Evaluation of Prime-boost Anti-pneumococcal Vaccination in Patients With Diffuse Large B Cell Lymphoma...

Pneumococcal InfectionsLymphoma2 more

Pneumococcal infections remain frequent and potentially fatal. To prevent them, two anti-pneumococcal vaccines exist: a 13-valent conjugate vaccine (Prevenar®) and a 23-valent polysaccharide vaccine (Pneumovax®). For their utilization, several studies approved a prime-boost strategy. It consist two administer Pneumovax® at least two months later than Prevenar®. Patients with diffuse large B-cell Lymphoma (DLBCL) have a higher-risk to develop a pneumococcal infection. The main reason is immunosuppression, induced by rituximab (B cell depletion), chemotherapy and lymphoma. Patients are treated by immunochemotherapy, combining rituximab (anti-CD20 monoclonal antibody) and conventional chemotherapy (CHOP). However, those patients have a low rate of vaccination (about 15%).
