Transcriptomic analysis of neutrophil apoptosis induced by diffuse large B-cell lymphoma unveils a potential role in neutropenia.

Background: Diffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma that arises from malignant transformation of B lymphocytes. Outcome of patients with DLBCL has been significantly improved by rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy, which is regarded "gold standard" of DLBCL therapy. It is unfortunate that febrile neutropenia, a decrease of the neutrophil count in the blood accompanying fever, is one of the most common complications that DLBCL patients receiving R-CHOP regimen experience.
