This study aimed to evaluate the prognostic impact of inflammation, nutritional status, and oxidative stress at diagnosis in patients with low-risk MDS. Methods: A retrospective analysis was conducted on 175 newly diagnosed low-risk MDS patients. Results: A low Prognostic Nutritional Index (PNI) and a high systemic oxidative stress (SOS) score were independently associated with poorer prognosis (PNI: HR 1.598, 95% CI 1.076\u20132.372, p = 0.02; SOS: HR 1.003, 95% CI 1.001\u20131.006, p = 0.002). The optimal PNI cut-off value for predicting mortality was identified as 47.47. Based on this cut-off, 92 patients had a low PNI score, while 83 patients had a high PNI score. The comparison between these groups revealed a statistically significant difference in median overall survival (OS), with 45.5 months for the low-PNI group and 75.1 months for the high-PNI group (p &lt; 0.001). However, PNI was not significantly associated with progression to acute myeloid leukemia (AML) (p = 0.668). In the multivariate OS analysis, several factors were identified as independent predictors of prognosis, including a high Revised International Prognostic Scoring System (R-IPSS) score, low PNI, high SOS score, advanced age, male gender, and transformation to AML. Conclusions: Together, PNI and SOS may serve as simple, accessible tools to improve risk stratification in low-risk MDS patients.<\/jats:p>","DOI":"10.3390\/jcm14134751","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T06:03:13Z","timestamp":1751868193000},"page":"4751","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prognostic Value of Inflammation and Nutrition-Based Scores in Low-Risk Myelodysplastic Syndrome: A Retrospective Cohort Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5419-3221","authenticated-orcid":false,"given":"Tuba","family":"Ersal","sequence":"first","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0014-7398","authenticated-orcid":false,"given":"Vildan","family":"\u00d6zkocaman","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9623-8096","authenticated-orcid":false,"given":"Sinem","family":"\u00c7ubuk\u00e7u","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4168-2821","authenticated-orcid":false,"given":"Tuba","family":"G\u00fcll\u00fc Koca","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4991-9830","authenticated-orcid":false,"given":"Faz\u0131l \u00c7a\u011fr\u0131","family":"Hunutlu","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1250-644X","authenticated-orcid":false,"given":"\u015eeyma","family":"Yavuz","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4389-9936","authenticated-orcid":false,"given":"Ezel","family":"Elg\u00fcn","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00f6khan","family":"Ocako\u011flu","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9710-134X","authenticated-orcid":false,"given":"Fahir","family":"\u00d6zkalemka\u015f","sequence":"additional","affiliation":[{"name":"Division of Hematology, Department of Internal Medicine, Faculty of Medicine, Bursa Uludag University, 16059 Bursa, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,4]]},"reference":[{"key":"ref_1","first-page":"2391","article-title":"The 2016 revision to the World Health Organization classification of myeloid neoplasms and acute leukemia","volume":"127","author":"Arber","year":"2016","journal-title":"Blood J.
