Methods: Clinical and radiomic data from 161 patients were retrospectively collected from a single center. Radiomic features were obtained from contrast-enhanced magnetic resonance imaging (MRI) T1-weighted (T1W), T2-weighted (T2W), and diffusion-weighted (DWI) sequences. After data cleaning, feature engineering, and scaling, survival prediction models were created using the CatBoost algorithm with different data combinations (clinical, clinical + T1W, clinical + T2W, clinical + DWI). The performance of the models was evaluated using test accuracy, precision, recall, F1-score, ROC curve, and Bland\u2013Altman analysis. Results: Models using both clinical and radiomic features showed significant improvements in accuracy and F1-score compared to models based solely on clinical data. In particular, the CatBoost_CLI + T2W_DMFS model achieved the best performance, with a test accuracy of 92.31% and an F1-score of 88.62 for distant metastasis-free survival prediction. ROC and Bland\u2013Altman analyses further demonstrated that this model has high discriminative power and prediction consistency. Conclusions: The CatBoost algorithm shows high accuracy and reliability for survival prediction in locally advanced cervical cancer when clinical and radiomic features are combined. The addition of radiomics data significantly improves model performance.<\/jats:p>","DOI":"10.3390\/curroncol32110602","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T05:48:46Z","timestamp":1761716926000},"page":"602","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Machine Learning-Based Prognostic Modelling Using MRI Radiomic Data in Cervical Cancer Treated with Definitive Chemoradiotherapy and Brachytherapy"],"prefix":"10.3390","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7928-6264","authenticated-orcid":false,"given":"Kamuran","family":"Ibis","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4848-5201","authenticated-orcid":false,"given":"Mustafa","family":"Durmaz","sequence":"additional","affiliation":[{"name":"Department of Radiology, Istanbul Faculty of Medicine, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5676-0293","authenticated-orcid":false,"given":"Deniz","family":"Yanik","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9846-5660","authenticated-orcid":false,"given":"Irem","family":"Bunul","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Erzurum City Hospital, 25240 Erzurum, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4773-3652","authenticated-orcid":false,"given":"Mustafa","family":"Denizli","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5007-7765","authenticated-orcid":false,"given":"Erkin","family":"Akyuz","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9455-6962","authenticated-orcid":false,"given":"Bayarmaa","family":"Khishigsuren","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1686-7114","authenticated-orcid":false,"given":"Ayca Iribas","family":"Celik","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9018-4736","authenticated-orcid":false,"given":"Merve Gulbiz Dagoglu","family":"Kartal","sequence":"additional","affiliation":[{"name":"Department of Radiology, Istanbul Faculty of Medicine, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6984-3466","authenticated-orcid":false,"given":"Nezihe Seden","family":"Kucucuk","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0563-5964","authenticated-orcid":false,"given":"Inci Kizildag","family":"Yirgin","sequence":"additional","affiliation":[{"name":"Department of Radiology, Institute of Oncology, Istanbul University, 34093 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9407-1728","authenticated-orcid":false,"given":"Murat","family":"Emec","sequence":"additional","affiliation":[{"name":"Computer Science Application and Research Centre, Istanbul University, 34116 Istanbul, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"74","author":"Bary","year":"2024","journal-title":"CA Cancer J.
