AI halved OAR contouring time but serial organs still required careful review
AI reduced six-OAR contouring workflow from about 20 to 9.5 minutes, while spinal cord and brainstem differences remained clinically relevant.

BNCT achieved high response but limited local control in recurrent oral cancer re-irradiation
Accelerator-based BNCT produced an 80% response and 51.1% two-year survival, but two-year local control was 31.8% with substantial toxicity.
Flap-sparing postoperative RT showed no intraflap recurrences in oral cavity cancer
Among 34 postoperative oral cavity cases, local failures occurred at or near the flap-native interface, with no recurrence inside the flap.
Extratumoral perineural invasion predicted worse outcomes after postoperative oral cavity radiotherapy
Extratumoral perineural invasion predicted poorer survival, while microscopic versus macroscopic extranodal extension did not meaningfully separate outcomes.
MRI deep learning identified oral tongue cancers associated with postoperative radiotherapy benefit
An MRI and pathology-based model identified a poor-risk oral tongue cancer group in which postoperative radiotherapy was associated with improved survival.
Smaller base-of-tongue volume was associated with prolonged feeding-tube dependence
Smaller base-of-tongue volume was associated with prolonged feeding-tube dependence after radiotherapy for oral cavity squamous cell carcinoma.
Postoperative radiotherapy provided better quality of life and value in oral cavity cancer
Postoperative conventional radiotherapy caused fewer head-and-neck symptoms and dominated preoperative accelerated radiotherapy in the five-year cost-utility analysis.
