Diffuse large B-cell lymphoma (DLBCL) is a cancer of B cells, a type of lymphocyte that is responsible for producing antibodies.It is the most common form of non-Hodgkin lymphoma among adults, [1] with an annual incidence of 7–8 cases per 100,000 people per year in the US and UK.
CD20. Approximately 95% of B-cell lymphomas express CD20, but CD20 is not critical for B-cell survival. Clonal B-cells spontaneously mutate the idiotypic region of their immunoglobulin. This high mutation rate makes them prone to the selection of B-cells lacking the CD20 antigen following treatment with CD20-targeting monoclonal antibodies.
The B-cell lymphomas are types of lymphoma affecting B cells. Lymphomas are "blood cancers" in the lymph nodes . They develop more frequently in older adults and in immunocompromised individuals.
Diffuse large B-cell lymphoma is the most common of the large-cell lymphomas. MeSH now classifies the phrase "large-cell lymphoma" under "Diffuse large B cell lymphoma". [2] Many other B-cell lymphomas feature large cells: [citation needed] Angiocentric lymphoma; Burkitt's lymphoma; Follicular large-cell lymphoma; Immunoblastic lymphoma
Primary central nervous system lymphoma (PCNSL), also termed primary diffuse large B-cell lymphoma of the central nervous system (DLBCL-CNS), [2] is a primary intracranial tumor appearing mostly in patients with severe immunodeficiency (typically patients with AIDS). It is a subtype and one of the most aggressive of the diffuse large B-cell ...
Among the various forms of B-cell lymphomas, THRLBCL is a rarely occurring subtype of the diffuse large B-cell lymphomas (DLBCL). DLBCL are a large group of lymphomas that account for ~25% of all non-Hodgkin lymphomas worldwide. [1] THRLBCL is distinguished from the other DLBCL subtypes by the predominance of non-malignant T-cell lymphocytes ...
