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.
Diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI) is a subtype of the Diffuse large B-cell lymphomas and a rare form of the Epstein–Barr virus-associated lymphoproliferative diseases, i.e. conditions in which lymphocytes infected with the Epstein-Barr virus (EBV) proliferate excessively in one or more tissues.
It has a 5-year overall survival rate of 40–55%, although the PCDLBCL-O variant has a better prognosis than cases in which the legs are involved. [ 5 ] Most lymphomas begin in a lymph node , mucosa-associated lymphoid tissue , the spleen , or another lymphoid tissue within the lymphatic system and then may spread to the skin.
A study of DLBCL cell lines indicated that 14-3-3ζ proteins may play a role in mediating resistance of DLBCL cells to CHOP. 14-3-3 proteins exert anti-apoptotic activity by interfering with the function of BH3-only proteins and has been validated as a potential molecular target for anticancer therapeutic development in other types of cancers.
Individuals with FA-DLBCL are typically males (~70% of cases) aged 25–96 years (~75% of cases are >50 years old). [6] They present with abnormalities associated with a long-standing (1–20 years [6]): a) cardiac myxoma (i.e. a myxoid tumor of primitive connective tissue in the heart's atrium); b) subdural hematoma (i.e. a collection of blood between the inner layer of the dura mater and the ...
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 ...

Epstein–Barr virus positive diffuse large B-cell lymphoma, not otherwise specified (EBV+ DLBCL, NOS) is a form of diffuse large B-cell lymphomas (DLBCL) accounting for around 10-15% of DLBCL cases. DLBCL are lymphomas in which B-cell lymphocytes proliferate excessively, invade multiple tissues, and often causes life-threatening tissue damage.
