Prognostic Molecular Markers in Patients With Myelodysplastic Syndrome

Prognostic Molecular Markers Determined by Using Gene Expression Profiling in Patients With Myelodysplastic Syndrome

In the era of hypomethylating agent in MDS treatment, the investigators aimed to investigate the prognostic impact of mutations in spliceosome machinery genes (SRSF2, U2AF1, and ZRSR2) on the outcomes of 1st line decitabine treatment in MDS.

A number of studies have tried to investigate clinical impact of mutations in spliceosomal machinery genes in MDS but they failed to demonstrate a consistent prognostic relevance. Moreover, the clinical impact of these mutations on the outcomes of hypomethylating agent treatment in MDS has never been explored yet. The investigators investigated the prognostic impact of mutations in spliceosome machinery genes (SRSF2, U2AF1, and ZRSR2) on the outcomes of 1st line decitabine treatment in MDS.

Inclusion Criteria:

• de novo MDS patients were included in the study who had received 1st line decitabine treatment and had adequate genomic DNA from pretreated bone marrow samples

Exclusion Criteria:

• therapy-related MDS
