We developed logistic NTCP models for severe acute\/late toxicities (grade \u2a7e3) using (i) the pATM-based RadioDtect test, (ii) clinical-dosimetric variables, and (iii) a combined model.

The RadioDtect test alone yielded moderate performance for late toxicity (AUC=0.65) and low discriminatory power for acute toxicity (AUC=0.57). Clinical-dosimetric models for acute toxicity demonstrated substantial predictive value (AUC=0.77), primarily driven by doses to the pharyngeal constrictor muscles and parotid glands. Integrating RadioDtect modestly improved discrimination for acute toxicity (AUC=0.82) but added no clinical utility (NRI=0%). Conversely, for late toxicity, doses showed poor association and discrimination for the occurrence of severe side effects. The biological refined NTCP model showed improved discrimination (AUC=0.76) and meaningful clinical utility (NRI=46.3%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The RadioDtect assay adds limited value for predicting acute toxicity in clinical settings entailing large volumes of organs at risk irradiated at high doses, but enhances NTCP models for late toxicity prediction.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03008916251367592","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T07:13:59Z","timestamp":1757920439000},"page":"420-432","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Predicting severe toxicity after head-and-neck cancer RT: Validation of the synergist role of a biological marker and dosimetry"],"prefix":"10.1177","volume":"111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0807-8323","authenticated-orcid":false,"given":"Sandrine","family":"Pereira","sequence":"first","affiliation":[{"name":"Neolys Diagnostics, Strasbourg-Entzheim, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7849-603X","authenticated-orcid":false,"given":"Tiziana","family":"Rancati","sequence":"additional","affiliation":[{"name":"Data Science Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola Alessandro","family":"Iacovelli","sequence":"additional","affiliation":[{"name":"Radiation Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirlande","family":"Duclos","sequence":"additional","affiliation":[{"name":"Neolys Diagnostics, Strasbourg-Entzheim, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elise","family":"Berthel","sequence":"additional","affiliation":[{"name":"Neolys Diagnostics, Strasbourg-Entzheim, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Deneuve","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Centre Hospitalier Universitaire Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8780-0734","authenticated-orcid":false,"given":"Anna","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Medical Physics Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4742-7672","authenticated-orcid":false,"given":"Domenico Attilio","family":"Romanello","sequence":"additional","affiliation":[{"name":"Radiation Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Fiorino","sequence":"additional","affiliation":[{"name":"Data Science Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Valdagni","sequence":"additional","affiliation":[{"name":"Radiation Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"},{"name":"Prostate Cancer Program, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"},{"name":"Department of Oncology and Hemato-Oncology, Universit\u00e0 degli Studi di Milano, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6495-8574","authenticated-orcid":false,"given":"Ester","family":"Orlandi","sequence":"additional","affiliation":[{"name":"Radiation Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2018.02.007"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.annonc.2020.12.007"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/CCO.0000000000000726"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.oraloncology.2016.06.019"},{"key":"e_1_3_2_6_2","doi-asserted-by":"crossref","unstructured":"Greco E.
