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.
EBV+ DLBCL, NOS was previously named Epstein–Barr virus-positive DLBCL of the elderly, by the WHO in 2008; because it appeared to be limited to people over the age of 50. [ 3 ] [ 4 ] : 369–370 [ 5 ] The name was changed to EBV+ DLBCL, NOS by the WHO in 2016, after the disease was described in much younger adults and children.
Diffuse large B-cell lymphoma, not otherwise specified; About 40–50% of lymphomas in adults Variable, most resemble B cells of large germinal centers, diffuse growth pattern Variable expression of CD10 and surface Ig Five-year survival rate 60% [36] Occurs in all ages, but most commonly in older adults, may occur outside lymph nodes, aggressive
Non-Hodgkin’s lymphoma (NHL) is one of the most common forms of blood cancer.1 The American Cancer Society estimates that about 81,560 people in the U.S. will be diagnosed with NHL and about ...

Median survival is 10 to 18 months in immunocompetent patients, and less in those with AIDS. The addition of IV methotrexate and folinic acid (leucovorin) may extend survival to a median of 3.5 years. If radiation is added to methotrexate, median survival time may increase beyond 4 years.
A review of 105 PEL cases reported median survival times, 1-year, 3-year, and 5-year survival rates of 4.8 months, 30%, 18%, and 17%, respectively. In this study, patients with advanced Ann Arbor Stage III or IV disease had a particularly poor survival rate at 1 year of 25%; this compared to a rate of 42% for patients with stage I or II disease ...
ABC subtype DLBCL, characterized by gene alterations (at CDKN2A) affecting NF-κB signaling, is associated with worse survival outcomes and increased CNS tropism. [14] Additionally, double-hit or triple-hit lymphomas, defined by chromosomal translocations involving MYC , BCL2 , and/or BCL6 oncogenes , confer higher risks of CNS recurrence. [ 13 ]
