Abstract: Objective

To establish protein fingerprinting model for the diagnosis of leukemia through determining 4 typical types of leukemia.

Methods

A total of 16 acute myeloblastic leukemia M2a samples, 18 chronic myelocytic leukemia samples, 14 acute lymphoblastic leukemia samples and 16 acute myeloblastic leukemia M3 samples were determined by protein fingerprinting technology. The comparison of biomarkers was performed by Biomarker Wizard and Biomarker Patterns 5.0 to establish a diagnosis tree model.

Results

The diagnosis tree model combined with 3 biomarkers ( m/z: 3 376, 8 055 and 9 421) could detect 75% acute myeloblastic leukemia M2a (12/16),100.0% chronic myelocytic leukemia (18/18), 71.4% acute lymphoblastic leukemia (10/14) and 87.5% acute myeloblastic leukemia M3 (12/14).

Conclusions

The protein fingerprinting model established by 3 protein features maybe a novel method for diagnosing 4 types of leukemia.
