Fonatsch C, Gudat H, Lengfelder E, Wandt H, Silling-Engelhardt G, Ludwig WD, Thiel E, Freund M, Bodenstein H, Schwieder G, et al. -T-cell receptor gene rearrangement to examine clonality of T cells in cases showing phenotypically aberrant T-cell population. A normal cell will display a pattern of antigens that correlates with the type and maturity of the cell. Furthermore, abnormal T-cell populations can be detected by using a panel of antibodies; . In patients with RAEB-t and CMML no CD34+ B-cell precursors could be detected. The blood of an older child or adult normally contains some mature B cells, but circulating immature B cells are not normally present. Now, if an adult has a small number of mature B cells but also has a large number of immature B cells which are positive for CD19 (remember, CD19 is a B-cell marker) and also positive for both CD34 and CD20 (which identifies those cells are both immature and abnormal), then the personhasan immature B-cell leukemia known as B-lymphoblastic leukemia. These plasma cells are negative for CD19. FOIA doi: 10.1371/journal.pone.0158827.

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. Trisomy 12 is the second most frequent aberration detected by fluorescence in situ hybridization at the time of diagnosis (10-25%), and it confers an . Flow cytometry immunophenotyping may be useful in helping to diagnose, classify, treat and determine prognosis of these blood cell cancers. ( 2011). Comparing cases with immunophenotypic dissimilarities to those with cytogenetic differences, no distinct patterns of association were identified. Your health care practitioner will consider the flow cytometry immunophenotyping results together with your clinical history, physical examination, signs and symptoms, as well as all laboratory tests to help make a diagnosis. The results of flow cytometry or immunocytochemistry should always be interpreted along with the available medical history, clinical signs, imaging findings, and pathologic results of individual cases. Careers. Sometimes pieces of the abnormal myeloma protein are filtered through the kidney into the urine. The results from your immunophenotyping are compared to the pattern of antigens for normal cells as well as to patterns that are associated with abnormal cells (e.g., cells present with leukemias and lymphomas). The prognostic value of immunophenotyping in AML is controversial [ 3]. The above negative findings can be attributed to low leukemia burden in the BMA. 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. Abnormal patterns of expression for at least one antigen was found in 91% of RA/RARS cases and in 74% of RAEB. 122 cases were also subjected to karyotype analysis by Gbanding technology and abnormal karyotypes were detected in 69 out of 122 patients.
