CD20 targeted therapy (Rituximab or cetuximab) is often useful in immunosuppressive therapy such as rheumatoid arthritis. Rituximab is also used to treat chronic lymphocytic leukemia (CLL) as it targets the mature B cells.
What is a CD20 treatment?
CD20 targeted therapy (Rituximab or cetuximab) is often useful in immunosuppressive therapy such as rheumatoid arthritis. Rituximab is also used to treat chronic lymphocytic leukemia (CLL) as it targets the mature B cells.
What is the role of CD20 in cancer?
Anti-CD20 monoclonal antibodies selectively deplete CD20+ B and CD20+ T cells and efficiently suppress inflammatory disease activity. These monotherapies prevent relapses, reduce new or active magnetic resonance imaging brain lesions, and lessen disability progression in patients with relapsing multiple sclerosis.
What happens when CD20 is positive?
CD20 mAbs can induce tumor killing in several ways. A. Direct binding of CD20 mAbs initiate the crosslinking of multiple CD20 molecules, resulting in cell-death via induction of non-classical apoptosis; B. Activation of complement result in complement-dependent cytotoxicity; C.
What drug is a CD20 marker?
The first hypothesis is that normal circulating CD20 positive T cells may undergo neoplastic transformation6, the second is that CD20 positive cells may react with normal B cells distributed among neoplastic T cells, and the third is that CD20 may be a marker of normal T cell activation16,17.
What cancers are CD20 positive?
CD20 is the target of the monoclonal antibodies rituximab, ocrelizumab, obinutuzumab, ofatumumab, ibritumomab tiuxetan, tositumomab, and ublituximab, which are all active agents in the treatment of all B cell lymphomas, leukemias, and B cell-mediated autoimmune diseases.
What is CD20 positive in tumor cells?
A protein found on B cells (a type of white blood cell). It may be found in higher than normal amounts in patients with certain types of B-cell lymphomas and leukemias. Measuring the amount of CD20 antigen on blood cells may help to diagnose cancer or plan cancer treatment.
What is CD20 negative cancer?
The positivity for CD20 in this tumour represents an aberrant immunophenotype, but it is not a B cell lymphoma, as shown by the negative immunoglobulin heavy chain gene rearrangement, and the absence of other B cell markers, such as CD79a and PAX5.
Is CD20 positive bad?
CD20 negative B cell non-Hodgkin lymphoma (NHL) is rare and accounts for approximately 1-2% of B cell lymphomas. CD20- negative NHL is frequently associated with extranodal involvement, atypical morphology, aggressive clinical behaviour, resistance to standard chemotherapy and poor prognosis.
What is normal range of CD20?
It may be found in higher-than-normal amounts in patients with certain types of B-cell lymphomas and leukemias. Measuring the amount of CD20 in blood cells may help to diagnose cancer or plan cancer treatment. CD20 is a type of tumor marker.
How to interpret CD20 results?
Reference ranges for CD10, CD19, and CD20 were found to be 1–3 (median 1%), 6–23 (median 14%), and 6–23 (median 14%), respectively (Table 2).
Where is CD20 found?
Interpretation. The presence of CD20+ B cells with corresponding absence of CD19 staining in individuals not receiving anti-CD20 monoclonal antibody treatment or with clinical features of variable primary humoral immunodeficiency may suggest an underlying CD19 deficiency, which should be further evaluated.
What is the test for CD20?
CD20 is a CD marker—a molecule on the cell surface that can be used to identify and type a particular cell in the body. CD20 is found on the surface of B cells, but let's back up and make this easier to understand.
What diseases are associated with CD20?
The CD20 flow cytometry assay quantitatively measures therapeutic B-cell depletion for patients on monoclonal anti-CD20 therapy such as Rituximab. Anti-CD20 therapies are used to treat patients with various types of B cell lymphoma, leukemia, and immune disorders.
Is Hodgkin's lymphoma CD20 positive?
CD20 is expressed in a vast majority of mature B-cell neoplasms and some cases of B-lymphoblastic leukemia/lymphomas, plasma-cell myelomas, Hodgkin lymphomas, T-cell neoplasms, and AMLs.
