IMMUNOPHENOTYPING IN ACUTE LEUKAEMIA- AN INSTITUTIONAL STUDY
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2018, Vol 5, Issue 7
Abstract
BACKGROUND Leukaemias are biologically a diverse group of disorders with differences in their morphology, antigen expression, chromosomal and molecular abnormalities, response to treatment, and prognosis. The main objective of the study was to compare morphological and flowcytometric diagnosis in patients diagnosed with acute leukaemia. MATERIALS AND METHODS The prospective study was carried out at S.C.B. Medical College and hospital, Cuttack, in department of Pathology and Clinical haematology, for the period of November 2015- November 2017. The findings were based on 100 patients who underwent both flow cytometry and peripheral smear/bone marrow morphology tests for diagnosis of acute leukaemia. RESULTS Using the peripheral smear/bone marrow morphology, 27% patients had ALL-L1, 38% had ALL-L2, 05% had AML-M1, 21% had AML-M2, 06% had AML-M3, 02% had AML-M4, and 01% had AML-M5. Immunophenotyping by flow cytometry confirms 50% patients to be B-ALL, 07% to be T-ALL, 32% AML, 08% APML/AML-M3, and 03% to be MPAL. There was a concordance between the morphological and flowcytometry of 88% in ALL, 91% in AML, 75% in APML, but, no concordance at all for MPAL. CONCLUSION Hence, flowcytometry is mandatory in all cases of acute leukemia, to confirm a definite diagnosis, as treatment nowadays is target oriented.
