Objective: To study the changes in overall outcome of patients with myelodysplastic syndromes (MDSs) after approval of several treatments.
Patients And Methods: We identified 54,953 MDS cases in the National Cancer Data Base diagnosed from January 1, 2004, through December 31, 2013, using International Classification of Diseases for Oncology, 3rd edition, codes 9980, 9982-9983, 9985-9987, 9989, 9991-9992. Overall survival and different subgroups were studied over 3 periods of diagnoses (2004-2006, 2007-2009, and 2010-2013).
Results: Median age at diagnosis was 76 years. The most common subtype was MDS-unclassifiable, which represented 55.6% of all cases. We found that males, older patients, patients with refractory anemia with excess blasts, Medicare insurance recipients, and those treated at nonacademic centers had the worse survival (P<.001). Overall survival did not improve over time, except in younger patients (<40 years old).
Conclusion: In the past decade, overall outcome of MDS did not improve despite the advent of new therapies. More studies are needed to understand the impact of newly approved treatments on the outcome of patients with MDS.

Background: Patients with secondary acute myeloid leukemia who previously received hypomethylating agents for prior myeloid neoplasms (HMA-sAML) face a dismal prognosis.
Methods: The authors analyze the characteristics, therapeutic approaches, and outcomes of patients with HMA-sAML from the Programa Español para el Tratamiento de Hemopatías Malignas (PETHEMA) registry.
Results: A total of 479 patients were included, mostly from prior myelodysplastic syndrome (84%).

Objective: To explore the mutation of gene in patients with myelodysplastic syndromes (MDS), and explore their correlation with mutations of other genes, clinical features and prognostic of patients.
Methods: High throughput DNA sequencing was used to identify mutations in common blood tumor genes. The mutational characteristics of the gene and the correlation between gene mutations and patients clinical characteristics and prognosis were retrospectively analyzed.

Objective: To explore the characteristics of gene mutation in patients with myelodysplastic syndrome (MDS) and its correlation with clinical features.
Methods: From January 2017 to December 2021, 172 patients with MDS in The First Affiliated Hospital of Bengbu Medical University were analyzed retrospectively. Fourteen high frequency genes related to MDS were detected, and the relationship between gene mutation and clinical characteristics of patients as well as revised International Prognostic Scoring System (IPSS-R) was analyzed.

Various prognostic models have been proposed to improve the accuracy of prognostic assessment for Myelodysplastic syndromes (MDS). Recently, the Molecular International Prognostic Scoring System (IPSS-M) has been developed. Here, we validated the accuracy of IPSS-M in Chinese MDS patients, and proposed a prognostic model more suitable for Chinese patients.

The outcomes of cardiac surgery in patients with hematologic disorders are significantly worse. However, details of the clinical course of each hematologic disease remain unclear. Myelodysplastic syndrome (MDS) presents with progressive pancytopenia that has the risk of infection, hemorrhage, and transformation to acute myelogenous leukemia.
