This study examines the immunohistologic profiles of a large series of histologically proven benign and malignant lymphoproliferative processes in order to define immunophenotypic criteria useful in the diagnosis of non-Hodgkin's lymphoma. 1. al. In general, these criteria involved identification of abnormal expression or loss of antigens in B- and T-lineage populations. While some antigens are found only on one type of cell, others are found on different types. Or it can be the result of a specific treatment. While hundreds of antigens have been identified and have a unique CD number, only a small number of these are routinely used. Several studies have identified a relationship between AML prognosis and antigens such as CD7, CD9, CD11b, CD13, CD14, CD15, CD33, CD34, and CD56, though some other studies report conflicting results. 2010 Sep;34(9):1235-1238. doi: 10.1016/j.leukres.2010.03.020, Immunophenotypic features by multiparameter, Shi M, Ternus JA, Ketterling RP, et al: Immunophenotypic and laboratory features of t(11;14)(q13;q32)-positive plasma cell neoplasms.

Immunophenotyping, a common application in flow cytometry, allows multiple cell surface markers to be simultaneously characterized on a per-cell basis.Immunophenotyping can be difficult by flow cytometry, however, when only a small number of cells are available. Last, the positive rate of Ki-67 expression in ANKL cells was generally high.

This form enables patients to ask specific questions about lab tests. More practically, and although the relationships demonstrated only represent a fraction of homogeneous immunophenotypic subgroups, identification of such immunophenotypic features should prompt careful karyotypic examination, eventually using molecular biology analysis on non-growing cells. The testing process begins with a screening panel. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis.

Leuk Res. This technique involves immunostaining of smears of fluids from body cavities or aspirates of tissues. Sometimes, however, the cancer cells adapt to evade the therapy by not expressing anymore an antigen that they expressed earlier, which might have been targeted by a monoclonal antibody or other therapy, like CAR T-cells. Immunophenotyping is widely used for the following reasons: Two types of tests are used in immunophenotyping: The choice of test is based on the type of sample: Heres a brief overview of the two types of test methods: In flow cytometry, the sample may range from blood, fluids in the body cavity (such as peritoneal or pleural fluids), bone marrow, or solid tissues in liquid media. -MYC break-apart at 8q24, with or without IGH-BCL2 t(14;18) and BCL6 break-apart at 3q27, for suspected high grade B-cell lymphomas, based on morphologic assessment and immunophenotype (usually CD10-positive).
