Key Points

To address the challenge of preventing fatal carotid blowout syndrome in patients undergoing repeat reirradiation for locally recurrent nasopharyngeal carcinoma.
Evaluated clinical options and complication risks for patients presenting with locally recurrent head and neck cancer following prior radiotherapy.
Carotid blowout syndrome occurs in fewer than 10% of patients receiving reirradiation.
The syndrome is fatal in more than 50% of cases, highlighting the need for accurate risk prediction and preventive surgical strategies.

Implication

Highlights the fatal risk of carotid blowout syndrome during reirradiation for recurrent head and neck cancer, indicating the critical need for preventive intervention.

Abstract

Local recurrence of head and neck cancer after radiotherapy remains a major therapeutic challenge1. Salvage surgery or chemotherapy are standard options but often limited by anatomy or patient condition, leaving re-irradiation as the only feasible choice in selected cases2. However, re-irradiation carries a substantial risk of carotid blowout syndrome (CBOS), occurring in fewer than 10% of cases but fatal in more than half3-5. Accurate prediction and prevention of CBOS are crucial.
