We examined absolute monocyte counts in the peripheral blood at the time of diagnosis in 1949 patients with a bone marrow blast count\u2009&lt;\u20095%, a condition we call MDS\u2009&lt;\u2009EB1 (MDS with a blast percentage lower than that of MDS with excess blasts 1, according to the WHO classification). Monocytosis (&gt;\u2009600\/\u00b5l) was associated with higher median hemoglobin, WBC, and ANC, and more favorable karyotype (<jats:italic>p<\/jats:italic>\u2009=\u2009.001). Nevertheless, monocytosis was associated with shorter overall survival (OS) (108 vs. 126\u00a0months, <jats:italic>p<\/jats:italic>\u2009=\u2009.002) and earlier transformation into AML (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). In patients with sideroblastic phenotype, the percentage of ring sideroblasts significantly correlated with the monocyte count (<jats:italic>p<\/jats:italic>\u2009=\u2009.005), and OS was significantly shorter when monocytosis was documented (88 vs. 132\u00a0months, <jats:italic>p<\/jats:italic>\u2009=\u2009.004). The survival disadvantage of patients with MDS\u2009&lt;\u2009EB1 and peripheral blood monocytosis suggests that these patients suffer from a CMML-like disease. Even though they are generally classified as MDS with persistent monocytosis, such patients should be considered candidates for therapeutic options employed in CMML.<\/jats:p>","DOI":"10.1007\/s00277-022-05043-y","type":"journal-article","created":{"date-parts":[[2022,11,21]],"date-time":"2022-11-21T06:09:01Z","timestamp":1669010941000},"page":"99-106","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Monocytosis at the time of diagnosis has a negative prognostic impact in myelodysplastic syndromes with less than 5% bone marrow blasts"],"prefix":"10.1007","volume":"102","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7642-6751","authenticated-orcid":false,"given":"A.","family":"Kasprzak","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Assadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Nachtkamp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Rudelius","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Haas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Giagounidis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"G\u00f6tze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Gattermann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"Germing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,11,21]]},"reference":[{"issue":"12","key":"5043_CR1","doi-asserted-by":"publisher","first-page":"2454","DOI":"10.1182\/blood-2012-03-420489","volume":"120","author":"PL Greenberg","year":"2012","unstructured":"Greenberg PL et al (2012) Revised international prognostic scoring system for myelodysplastic syndromes.
