The treatment plans included three hybrid applicator types: tandem and ovoids combined with interstitial needles, tandem and ring combined with interstitial needles, and tandem and cylinder combined with interstitial needles. The model was validated on the testing dataset using mean absolute error (MAE) for voxel-wise dose evaluation and on the clinical evaluation dataset using dice similarity coefficient (DSC) and dose statistic differences.\n                    <jats:italic>Main results.<\/jats:italic>\n                    The model achieved a voxel-wise MAE of 0.45 \u00b1 0.27 Gy and showed no statistically significant differences (\n                    <jats:italic>p<\/jats:italic>\n                    &gt; 0.05) in all key dose-volume histogram parameters when compared to clinical plans. The DSC values ranged from 0.74 to 0.77. Small dosimetric differences between the optimized and manually generated plans were observed for the high-risk clinical target volume (HR-CTV) D98%, HR-CTV D90%, and bladder D2cc.\n                    <jats:italic>Significance.<\/jats:italic>\n                    The developed dose prediction model demonstrates significant potential for application in hybrid applicator brachytherapy. This model can provide guidance for dose delivery during dwell time optimization. As a reference for optimization, it has the potential to streamline the planning process, reduce planning time, and improve consistency in adaptive workflows.\n                  <\/jats:p>","DOI":"10.1088\/1361-6560\/ae7cd4","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T07:13:59Z","timestamp":1782890039000},"page":"135008","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Deep learning-based dose prediction to enhance planning efficiency in cervical brachytherapy with hybrid applicators"],"prefix":"10.1088","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0523-352X","authenticated-orcid":true,"given":"Sangutid","family":"Thongsawad","sequence":"first","affiliation":[{"name":"Chulabhorn Hospital"},{"name":"Chulabhorn Royal Academy"},{"name":"Personalized Radiotherapy and Imaging in Medicine (PRIME) Research Center, Chulabhorn Royal Academy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nawarat","family":"Rinjan","sequence":"additional","affiliation":[{"name":"Chulabhorn Royal Academy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekkasit","family":"Tharavichitkul","sequence":"additional","affiliation":[{"name":"Chiang Mai University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1802-9720","authenticated-orcid":true,"given":"Chirasak","family":"Khamfongkhruea","sequence":"additional","affiliation":[{"name":"Chulabhorn Hospital"},{"name":"Chulabhorn Royal Academy"},{"name":"Personalized Radiotherapy and Imaging in Medicine (PRIME) Research Center, Chulabhorn Royal Academy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chirapha","family":"Tannanonta","sequence":"additional","affiliation":[{"name":"Chulabhorn Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thananya","family":"Chanpanya","sequence":"additional","affiliation":[{"name":"Chulabhorn Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,7,1]]},"reference":[{"key":"pmbae7cd4bib1","doi-asserted-by":"publisher","first-page":"660","DOI":"10.6004\/jnccn.2020.0027","type":"journal-article","article-title":"NCCN guidelines insights: cervical cancer, version 1.2020: featured updates to the NCCN guidelines","volume":"18","author":"Abu-rustum","year":"2020","journal-title":"J.
