Background and Aim of Study: There are two different phases of untreated chronic myeloid leukemia – chronic phase, and blast crisis – according to the World Health Organization classification of Hematolymphoid tumors. The blast cells in the chronic myeloid leukemia blast crisis can express myeloid, lymphoid, bi-phenotypic, monocytic, megakaryocytic, and erythroid phenotypes. The immunophenotype of blast population determines how chronic myeloid leukemia – blast crisis patients respond to treatment, hence flowcytometric examination is required. The aim of the study: to assess immunophenotyping outcomes of flowcytometry performed on the chronic myeloid leukemia – blast crisis. Material and Methods: A five-year retrospective descriptive analysis was carried out in Pathology Department at King George’s Medical University Lucknow, India (2017-2021). The patient’s peripheral blood and bone marrow aspirate samples were analyzed. Clinical, hematological, and immunophenotypic data were retrieved. The flow cytometry samples were prepared using the standardized “lyse-stain-wash” method. Results: A total of 43 cases of chronic myeloid leukemia – blast crisis were retrieved from the departmental archive in 5 years. The mean age of study population was 39.62±14.86 years. There were 24 males and 19 females. 27 patients were diagnosed with myeloid blast crisis, 14 cases of B-lymphoid blast crisis and 2 cases of mixed phenotypic acute leukemia. Conclusions: Identification of the blast lineage of patients with chronic myeloid leukemia – blast crisis is crucial since the existence of atypical blast phenotypes influences the disease treatment and prognosis. |
