Median time to PORT was 8.57\u2009weeks (interquartile range, 2.86). Random forest modeling identified postoperative length of stay (LOS), margin status, concurrent systemic therapy, and readmission within 60\u2009days as the variables contributing most to prediction of PORT timing. Univariate analysis identified postoperative LOS as the only significant predictor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Earlier multidisciplinary coordination may improve PORT timeliness in integrated health systems.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/hed.70480","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T02:01:00Z","timestamp":1789610460000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Demographic and Clinicopathological Factors Associated With Delayed Postoperative Radiotherapy in Patients With Resected Oral Cavity Cancer"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-7807-9114","authenticated-orcid":false,"given":"Kasey","family":"Bowyer","sequence":"first","affiliation":[{"name":"Kaiser Permanente Bernard J.
