Abstract:
Objective To investigate the laboratory examination,diagnosis and treatment of 57 cases of Acute Promyelocytic Leukemia.Methods The clinical manifestation,laboratory morphology-immunology-cytogenetics-molecular (MICM) classification,treatment and follow-up were analyzed retrospectively among 57 newly diagnosed cases of acute pmmyelocytic leukemia (APL) patients from January 2011 to December 2013 in Xiangya Hospital,Central South University.Results In 57 patients,the first symptom was given priority to with bleeding (73.7％),fever (26.3％),and the organ infiltration accounted for 29.8％.The phenotype of CD13 + CD33 + CD34-HLD-RA-was 59.6％ in 57 patients,CD13 + CD33 +CD34 + HLD-RA + was 8.8％,and the remaining 18 cases were not classic phenotypes.The positive percentage of PML/RARa was 93.0％ by fluorescence in situ hybridization (FISH),and the remaining 4 cases were other rare abnormal.Except one case gave up the treatment,the other 56 cases of APL patients reached 100％ complete remission rate under early screening and diagnosis,relatively standardized and effective treatment.Conclusions Hemorrhage is the most common clinical symptoms of M3.MICM classification,especially the FISH technology,is the main laboratory basis for diagnosis of M3.After the treatment of early specifications currently,M3 can almost be cured.
