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 (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.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
Diffuse large B-cell lymphoma (DLBCL) is a type of high-grade NHL which is the most common type of NHL worldwide at affecting 30–40 percent of all NHL cases. [4] It is more prevalent in elderly patients with a median age of 70 years. Patients most often present with a rapidly growing tumor mass in single or multiple, nodal or extranodal sites.
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 most common chemotherapy used for B-cell non-Hodgkin lymphoma is R-CHOP, which is a regimen of four drugs (cyclophosphamide, doxorubicin, vincristine, and prednisone) plus rituximab. [ 33 ] R-CHP with polatuzumab vedotin , an antibody-drug conjugate, was included as a category 1 preferred regimen for first-line DLBCL by the National ...
Plasmablastic lymphoma lesions are most commonly rapidly growing, soft tissue masses [5] that may be ulcerating, bleeding, and/or painful. [6] In a recent (2020) review of published cases, individuals presenting with PBD were typically middle-aged or elderly (range 1–88 years; median age 58 tears) males (~73% of cases). [7]
