Single-Cell Map of Immune and Lymphoma Cells in B-cell Non-Hodgkin's Lymphoma

CompletedNA

Sponsor: Institut Claudius Regaud

Conditions: Diffuse Large B-cell Lymphoma

Interventions: Patient with histologically confirmed diffuse large B-cell lymphoma with a planned first line treatment by R-CHOP.

Countries: France

This trial is a translational, prospective, open-label, monocentric research. The study will be conducted in a population of 60 patients with diffuse large B-cell lymphoma (DLBCL) for whom first-line treatment with R-CHOP is planned as part of their standard of care. SIMILY program aims at identifying biomarkers and/or molecular signatures related to immuno-phenotypic and -genotypic characteristics of the tumor and immune microenvironment, at the time of diagnosis, during R-CHOP, and at 24 months or time of progression. Each patient will be followed during 2 years.
