Overview

Monocytopenia is a common finding in patients with myelodysplastic syndrome (MDS), but although monocytes may exhibit prognostic significance in MDS due to their role in innate immunity, they have not been incorporated in any prognostic scoring system for MDS. In this study, we analyzed national registry data from 1719 adults with MDS. Monocytopenia was present in 29.5% of the patients and was correlated with the presence of excess blasts and higher revised international prognostic scoring system categories. Univariate analysis showed that monocytopenia was prognostic of a lower overall survival [(OS), 32.0 versus 65.0 months, p < 0.001], while it retained its prognostic significance in a multivariate model comprising anemia, neutropenia and thrombocytopenia [hazard ratio (HR) for OS, 1.320, p < 0.001]. Moreover, it was prognostic of a lower leukemia free survival (LFS) both in univariate analysis and in a multivariate model comprising cytopenias, bone marrow blasts, and cytogenetic risk (HR for LFS 1.27, p = 0.031). The findings regarding OS and LFR were exclusive or more pronounced in lower risk patients, respectively. Moreover, monocytopenia could divide the low and intermediate risk groups of IPSS-R in prognostically distinct subgroups. Our results redefine the prognostic role of monocytes in MDS and set the basis for further studies to validate our results and expand our knowledge on the prognostic significance of monocytopenia in MDS.
