  1. 1. CLINICAL PATHOLOGY UPDATE on SURAMADE ISurabaya, 15th Juliy 2011 YETTI HERNANINGSIH, dr., SpPK Clinical Pathology Department Dr. Soetomo Hospital Surabaya
  2. 2. (Gorczyca W, Emmons FM, 2008) 2
  3. 3. Flow cytometric immunophenotyping is important for the Distinction between ALL and AML, identification of B-cell or T-cell lineage Assessing response to treatment, including the detection of MRD Detection aberrant expression 3
  4. 4. SAMPLE STAINING 1.SURFACE ANTIGEN 2.INTRACELLULAR ANTIGEN (TdT, cCD3, cCD22, MPO) 3.DNA CONTENT 4
  5. 5. 5
  6. 6. 6(Gorczyca W, Emmons FM, 2008)
  7. 7. Immunophenotyping of AML(Campana & Behm,2000) 7

  10. 10. Figure 6.22 Schematic illustration of antigen expression during normal T-cell and NK-cellmaturation. Note that, although the common lymphoid stem cell presumably arises in the bone marrow, most T-cell maturation occurs in the thymus. As with the B cells (Fig. 6.12), T-cell activation occurs after exposure to antigen.(Courtesy Dr. Dan Sabath.) 10 (Tkachuk DC, Hirschmann JV, 2007)

  12. 12. (Concise Manual of Hematology and Oncology, 2008) 12
  13. 13. Biphenotypic Acute Leukemia If > 2 points is scored for both myeloid and one of the lymphoid lineages the case is classified as biphenotypic 13
  14. 14. Undifferentiated Acute Leukemias Rare subgroup of acute leukemias which cannot be further classified using the above mentioned criteria. Usually CD34+, HLA-DR+, CD38+, and CD7+. 14
  15. 15. ABERRANTImmature B cell Abberant : co express an antigen of different lineage e.g. CD 65 (myeloid antigen) expressed on an immature B cell (CD19+, CD34+, cyCD22+, cyCD79a+, TdT+) 15
  16. 16. How to store and send sample for Immunophenotyping • Bone marrow (BM) aspirate orSpecimen Whole blood (WB) with EDTA • No blood clot or hemolysisStorage and • At room temperature (never be Transport transported on dry ice) • 24 hours, send to lab as soon as Stability possible 16
  17. 17. How to store and send sample for ImmunophenotypingHemogram • Should be accompanied (if present)Schedule • Every working day Report • 1 working days issues 17
  18. 18. Panel of antibodies recommended by European Group for theImmunoloogical Characterization of aleukemia (EGIL) fordiagnosis and classificatin of acute leukemia (1995) (Courtesy Sayed DM) 18
  19. 19. Application of Immunophenotyping at Dr. Soetomo Hospital CD7 FITC/CD33 PE/CD45 PerCPHLA-DR FITC/CD13 PE/CD45 PerCP CD19 FITC/CD10 PE/CD45 PerCP CD3 FITC/CD34 PE/CD45 PerCP CD5 FITC/CD20 PE/CD45 PerCP 19
