Abstract
INTRODUCTION Prognosis of patients with myelodysplastic syndrome (MDS), particularly the group with lower-risk disease (LR-MDS) is very heterogeneous. Several studies have described the prognostic value of recurrent somatic mutations in MDS including all risk categories. Recently, the incorporation of genomic data to clinical parameters defined the new Molecular International Prognostic Scoring System (IPSS-M). MATERIALS AND METHODS In this study, we evaluated the impact of molecular profile in a series of 181 patients with LR-MDS and non-proliferative chronic myelomonocytic leukemia. RESULTS Epigenetic regulators (TET2, ASXL1) and splicing (SF3B1) were the most recurrent mutated pathways. In univariate analysis, RUNX1 or TP53 mutations correlated with lower median overall survival (OS). In contrast, SF3B1 mutation was associated with prolonged median OS [95 months (95% IC, 32-157) vs. 33 months (95% CI, 19-46) in unmutated patients (P < 0.01)]. In a multivariate Cox regression model, RUNX1 mutations independently associated with shorter OS, while SF3B1 mutation retained its favorable impact on outcome (HR: 0.24, 95% CI, 0.1-0.5; P = 0.001). In addition, TP53 or RUNX1 mutations were identified as predictive covariates for the probability of leukemic progression (P < 0.001). CONCLUSION Incorporation of molecular testing in LR-MDS identified a subset of patients with expected poorer outcome, either due to lower survival or probability of leukemic progression.

Abstract
BACKGROUND The implication of mutational variant allelic frequency (VAF) has been increasingly considered in the prognostic interpretation of molecular data in myeloid malignancies. However, the impact of VAF on outcomes of myelodysplastic syndromes (MDS) has not been extensively explored. METHODS Targeted next-generation sequencing was performed in 350 newly diagnosed MDS cases. The associations of mutational VAF of each gene with overall survival (OS) and leukemia-free survival (LFS) were examined by multivariate Cox regression after univariate analysis. RESULTS Shorter OS was independently associated with DNMT3A VAF (HR 1.020 per 1% VAF increase; 95% CI 1.005-1.035; p = 0.011) and TP53 VAF (HR 1.014 per 1% VAF increase; 95% CI 1.006-1.022; p = 0.001). LFS analyses revealed that TET2 VAF (HR 1.013 per 1% VAF increase; 95% CI 1.005-1.022; p = 0.003) and TP53 VAF (HR 1.012 per 1% VAF increase; 95% CI 1.004-1.021; p = 0.005) were independently associated with faster leukemic transformation. Furthermore, we established nomograms to predict OS and LFS, respectively, by integrating independent mutational predictors into the revised International Prognostic Scoring System. CONCLUSION Our study highlights that VAF of certain genes should be incorporated into routine clinical prognostication of survival and leukemic transformation of MDS.
