These newer treatments may have reduced side effects compared to conventional chemotherapy (newer targeted therapies are usually added to traditional chemotherapy). Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. Craig, F. and Foon, K. (2008 April 15). Immunophenotyping has become extremely important not only in diagnosis and subclassification of AML but also in the detection of the minimal residual disease.

Flow cytometry immunophenotyping may be ordered when you have an increased number of lymphocytes (or sometimes an increase in another type of white blood cell, WBC), anemia, a decreased platelet count, or immature WBCs that are not normally seen in the blood. The volume of fluid necessary to phenotype the lymphocytes or blasts in serous effusions depends upon the cell count in the specimen. Acute myeloid leukemias (AMLs) are hematologic malignancies with varied molecular and immunophenotypic profiles, making them difficult to diagnose and classify.

Both mature and immature B cells are normally positive for the CD19 marker. This technique helps in prognostication and is also used to differentiate between neoplastic and reactive expansions of lymphocytes. Information about the potential relationship between genetic abnormalities and immunophenotypic markers is currently limited to the association found between t(11;14 . Second, unusual expression of surface antigens in ANKL cells was a prominent feature. J Immunol. When cell counts drop below 5 cells/mcL, the immunophenotypic analysis may not be successful.

Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. Smaller volumes can be used if there is a high cell count. Background Myeloid Sarcoma with monocytic differentiation is rare and quite likely is missed by surgical pathologists. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. This process is widely used to diagnose different types of lymphoma and leukemia by comparing normal cells and cancer cells. Most of the antigens that flow cytometry immunophenotyping detects are identified by a CD (clusters of differentiation or cluster designation) number. Methods: Morphologic evaluation, flow cytometry immunophenotypic studies . Flow cytometry immunophenotyping may be performed on blood, bone marrow, or other samples to provide this additional information. What is Immunophenotyping?. Body fluid samples are obtained through collection of the fluid in a container or by inserting a needle into the body cavity and aspirating a portion of the fluid with a syringe.
