Pfeffer 1, Marcel Fang1, Yael Misrati 1, Noam Weizman1, Jon Feldman 1† and Aron Popovtzer 1†  \nAbstract  \nBackground Adaptive radiation therapy (ART) offers a dynamic approach to address structural and spatial changes that occur during radiotherapy (RT) for locally advanced head and neck cancers. The integration of daily ART  \nwith Cone-Beam CT (CBCT) imaging presents a solution to enhance the therapeutic ratio by addressing inter-fractional changes.  \nMethods We evaluated the initial clinical experience of daily ART for patients with head and neck cancer using an online adaptive platform with intelligence-assisted workflows on daily CBCT. Treatment included auto-contour and structure deformation of Organs at Risk (OARs) and target structures, with adjustments by the treating physician. Two plans were generated: one based on the initial CT simulation with the edited structures (scheduled) and a reoptimized plan (adaptive) . Both plans were evaluated and the superior one approved and delivered. Clinical and dosimetric outcomes were reviewed.  \nResults Twenty two patients with head and neck cancers (7 Nasopharynx, 6 Oropharynx, 1 oral cavity, 8 larynx) stages I-IVA were treated with daily ART. 770 adaptive and scheduled radiotherapy plans were generated. 703 (91 . 3%) adaptive plans were chosen. Median time to deliver ART was 20 minutes (range: 18-23) . Adaptive compared to scheduled plans demonstrated improved mean V95 values for the PTV70, PTV59 . 5, and PTV56 by 1. 2%, 7. 2%, and 6. 0% respectively and a mean 1.4% lower maximum dose in PTV70 . Fourteen of 17 OARs demonstrated improved dosimetry with adaptation, with select OARs reaching statistical significance. At a median follow up of 14.1 months, local control was 95. 5%, two patients developed metastatic disease and four patients died. 9. 1% of patients had acute grade 3 dysphagia and 13. 6% had grade 2 chronic xerostomia.  \n†Principal Investigators: equal contribution  \n*Correspondence:  \nPhilip Blumenfeld [philipb@hadassah.org.il](philipb@hadassah.org.il)  \n1 Department of Radiation Oncology, Sharett Institute of Oncology, Hadassah Medical Center and Faculty of Medicine, Hebrew University of Jerusalem, POB 12272, 9112002 Jerusalem, Israel  \n2 Department of Radiation Oncology, Thomas Jefferson University Hospital, Philadelphia, PA, USA  \n© The Author(s) 2024, corrected publication 2024.
