These newer treatments may have reduced side effects compared to conventional chemotherapy (newer targeted therapies are usually added to traditional chemotherapy). Nat Rev Immunol v12 (3): 191200. The volume of fluid necessary to phenotype the lymphocytes or blasts in serous effusions depends upon the cell count in the specimen. These antigens are protein structures found on or within WBCs. Immunologic monitoring in adults with acute lymphoblastic leukemia. Flow cytometry immunophenotyping may also be used: There are some other uses of this testing that are less common, but they are not addressed in this article. No flow cytometric abnormalities were detected in CD4-positive T-cells from 10 control patients without lymphoproliferative disorders. Abnormal patterns of expression for at least one antigen was found in 91% of RA/RARS cases and in 74% of RAEB. A correlation study of immunophenotypic, cytogenetic, and clinical features of 180 AML patients in China . This case suggested that chromosomal alterations may precede morphological, flow cytometric and clinical changes and accelerate progression of the disease. MedlinePlus Medical Encyclopedia [On-line information]. 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. If the CT scan said that there are no significant abnormalities it means that nothing out of the ordinary was noted. 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 intermediate prognostic risk, with a median time to . The abnormal cells grow, but they do not fight infections or perform other functions like normal WBCs. The lady explained that that meant I didn't have anything preconcerous, but she didn't see to know what it DID mean.
