Abstract:
Objective:To investigate the clinical significance of the detection of cell surface marker and chromosome in diagnosis,treatment and prognosis of leukemia. Methods:Morphologic typing and immunophenotyping were carried out in 22 untreated patients with leukemia respectively with FAB criteria and monoclonal antibodies(McAb) which were used to label cell surface marker. Chromosomal specimens were prepared by 48-hour culture method. Chromosome was analysed by G-banding technique. Results:All the 22 cases were diagnosed as leukemia by combined detection of morphology and immunology. Among them there were 8 acute lymphocytic leukemia(ALL) in which 2 cases expressed myeloid lineage-associated antigens(My+ ALL),9 acute meylocytic leukemia(AML) and 3 chronic lymphocytic leukemia(CLL). In addition,2 cases were diagnosed as acute undifferentiated leukemia(AUL). Chromosomal karyotype analysis was carried out in 17 cases,among which chromosomal abnormalities were found in 11 cases in which 2 cases with complex chromosomal deformity had non-remission(NR). With the exception of the 2 cases aforementioned,others had complete remission(CR). Conclusion:The proper detection of cell surface marker and chromosome on limited condition is helpful for the diagnosis of leukemia,which would provide an experimental evidence for personalized treatment and prognosis.
