[Impact of Mutation on Treatment Response and Survival of Patients with Acute Myeloid Leukemia].

Objective: To investigate the expression of mutation in acute myeloid leukemia (AML) and analyze its clinical characteristics and prognosis.

Methods: A retrospective study was conducted in 212 patients with AML who were newly diagnosed in the Second Hospital of Shanxi Medical University from January 1th 2018 to June 30th 2021, including 22 patients with mutations as mutation group and 190 patients with wild type ［66 cases of them were screened by propensity score matching (PSM), as control group］. The early efficacy and survival between the two groups were compared.

The clinical characteristics and prognosis of Chinese acute myeloid leukemia patients with CSF3R mutations.

Introduction: The colony-stimulating factor 3 receptor (CSF3R) controls the proliferation of myeloid progenitors and differentiation into neutrophils. However, the clinical features and prognostic significance of CSF3R mutations in primary acute myeloid leukemia (AML) patients are still unclear.

Methods: 158 newly diagnosed AML patients were retrospectively evaluated in our study.

[Quantitative Analysis on Immunophenotype of CD34 Myeloid Precursor Cells in Myelodysplastic Syndrome and Its Correlation with Clinical Features].

Objective: To investigate the quantitative expression of immunophenotype of CD34 myeloid precursor cells in myelodysplastic syndrome (MDS) patients and its correlation with clinical characteristics, and understand the effect of quantitative expression of CD7 and CD117 on the prognosis of low-risk MDS patients.

Methods: Multi-parameter flow cytometry (FCM) was used to detect the proportion and mean fluorescence intensity (MFI) of each antigen of bone marrow CD34 myeloid precursor cells in 79 MDS patients. The correlation between the expression level of each immune marker and clinical characteristics was compared.

Droplet digital PCR for BCR/ABL(P210) detection of chronic myeloid leukemia: A high sensitive method of the minimal residual disease and disease progression.

Objective: This study intended to establish a droplet digital PCR (dd-PCR) for monitoring minimal residual disease (MRD) in patients with BCR/ABL (P210)-positive chronic myeloid leukemia (CML), thereby achieving deep-level monitoring of tumor load and determining the efficacy for guided clinically individualized treatment.

Methods: Using dd-PCR and RT-qPCR, two cell suspensions were obtained from K562 cells and normal peripheral blood mononuclear cells by gradient dilution and were measured at the cellular level. At peripheral blood (PB) level, 61 cases with CML-chronic phase (CML-CP) were obtained after tyrosine kinase inhibitor (TKI) treatment and regular follow-ups.
