Sometimes lymphomas also involve the blood and/or bone marrow. Accessed December 2014. As mentioned, the immunophenotypic panels used evolved during the study, and not all antigens were studied in the entire MDS patient group . If no abnormalities are detected by the initial panel, no further flow cytometric assessment will be performed unless otherwise indicated by specific features of the clinical presentation or prior laboratory results. Smaller volumes can be used if there is a high cell count. 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. This test was developed using an analyte specific reagent. doi: 10.1371/journal.pone.0158827. Rarely, no overt immunophenotypic abnormality will be present at diagnosis, and in these cases, the sensitivity of flow cytometric evaluation for minimal residual disease may be greatly reduced. 2. Khalidi HS, Medeiros LJ, Chang KL, Brynes RK, Slovak ML, Arber DA. Morphologic evaluation and flow cytometric immunophenotypic analysis revealed no evidence of plasma cell neoplasm involving the BM. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. An internal organ may or may not be a little bigger or a little smaller than normal but this is insignificant and no cause for worry. Flow cytometric immunophenotyping is a valuable addition to morphology in the diagnosis of MDS in adults.7 Abnormalities detected by flow cytometry in myelomonocytic, . Leukemias and lymphomas are caused by an abnormal white blood cell that begins to divide uncontrollably, making numerous copies of itself (clones). 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. I got thre results today, which were "no significant abnormalities". Careers.

The dysplastic features are not unique for AML-MRC, but can be also detected in other hematopoietic diseases, such as MDS (Wu et al., 2013). For solid tissue specimens, order LLPT / Leukemia/Lymphoma Immunophenotyping, Flow Cytometry, Tissue. In agreement with previous studies, no immunophenotypic features (other than monocytic differentiation) predicted the presence of an 11q23 rearrangement. 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. MDS is distinguished from other disease processes by a pattern of multiple myeloid immunophenotypic abnormalities (3-6). 1. Cheriyedath, Susha.

Sometimes, a tissue sample, such as from a lymph node, is obtained using a biopsy or fine needle aspiration (FNA) procedure. The triage panel also includes antibodies to assess the number of CD3-positive T cells and CD16-positive/CD3-negative natural killer (NK) cells present. Cheriyedath, Susha. 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. The referring physician or pathologist will be contacted to confirm the addition of any of these tests. A blood sample is obtained by inserting a needle into a vein. With the exception of the MB2 B-cell-associated antigen, no B- and T-cell differentiation antigen was detected in case 1. 122 cases were also subjected to karyotype analysis by Gbanding technology and abnormal karyotypes were detected in 69 out of 122 patients.

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. The above negative findings can be attributed to low leukemia burden in the BMA. 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.
