This study was aimed to investigate the efficacy of moderate intensity regimen, CHG (homoharringtonine, cytarabine and granulocyte colony-stimulating factor (G-CSF)) on the patients with high-risk MDS or MDS-transformed acute myeloid leukemia. 30 newly diagnosed adult patients with high-risk MDS or MDS-transformed AML were enrolled in this clinical trial to(More)
To identify the molecular signatures that predict responses to decitabine (DAC), we examined baseline gene mutations (28 target genes) in 109 myelodysplastic syndrome (MDS) patients at diagnosis. We determined that TP53 mutations predicted complete response (CR), as 10 of 15 patients (66·7%) who possessed TP53 mutations achieved a CR. Univariate and(More)
Abnormal immunophenotypes of hematopoietic cells can be detected by flow cytometry (FCM) to assist the diagnosis of myelodysplastic syndromes (MDS). We previously established a FCM scoring system for the diagnosis of low-grade MDS. In this study, additional valuable antigens were involved in an updated FCM scoring system (u-FCMSS) for all MDS subtypes. The(More)
Novel sequencing designs are necessary to supplement the recognized knowledge of myelodysplastic syndrome (MDS)-related genomic alterations. In this study, we sequenced 28 target genes in 320 Chinese MDS patients but obtained 77.2% of recall factors and 82.8% of genetic abnormalities (including karyotype abnormalities). In addition to known relationships(More)
The progressive mechanism underlying myelodysplastic syndrome remains unknown. Here we identify ROBO1 and ROBO2 as novel progression-related somatic mutations using whole-exome and targeted sequencing in 6 of 16 (37.5%) paired MDS patients with disease progression. Further deep sequencing detects 20 (10.4%) patients with ROBO mutations in a cohort of 193(More)
Decitabine treatment improves immunological recognition that increases expression of cancer-testis antigens (CTAs) against solid tumors. The mechanisms of decitabine enhancement of immunogenicity when used for patients with myelodysplastic syndromes (MDS) remain unclear. In the present study, we found relatively low baseline expression of MAGE-A1, MAGE-A3,(More)
Decitabine is an effective therapy for patients with lower risk myelodysplastic syndrome (MDS). However, the mechanisms of decitabine's therapeutic effect are not well established. Forty-four lower risk MDS patients received decitabine therapy. 59.1% patients achieved treatment response, and 53.8% patients who were RBC/platelet-dependent cast off the(More)
Clinical application of flow cytometry in multiple myeloma (MM) can be found in various dimensions, such as in differential diagnosis of malignant plasma cell disorder from reactive plasmacytosis, identification of the progression risk in MM, and in the detection of minimal residual disease. Flow cytometry-based clonality assessment with immuno-phenotyping(More)
To investigate the tumoricidal activity of dendritic cell (DC) stimulated by interferon-gamma (IFN-gamma) against freshly isolated myeloid leukemia cells and its mechanism, the peripheral blood monocytes collected from healthy donors were cocultured with interleukin-4 and granulocyte-macrophage colony-stimulating factor in medium to induce DC for 7 days.(More)
This study was aimed to explore the significance of the bone marrow biopsy for the diagnosis of multiple myeloma. Bone marrow smears and bone marrow biopsy originated from 279 cases of multiple myeloma were detected and compared in term of bone marrow hyperplasia, bone marrow plasma cell infiltration, proliferation mode, pathological changes in the bone(More)
