Conclusion:
In LANC patients whose carotid artery invasion was <270º, HT combined with CCRT and EGFR inhibitor after induction chemotherapy had mild and tolerable side effects, better PFS and DMFS, with no massive hemorrhage. In patients ≥270º, diabetes with poor control or re-radiotherapy led to a higher risk of massive hemorrhage after radiotherapy.
