ABSTRACT
OBJECTIVES:
Carotid blowout syndrome (CBS) is a rare, life-threatening complication for patients with head and neck cancer (HNC). The primary objective was to identify factors associated with survival following CBS. MATERIALS ANDMETHODS:
A retrospective analysis of HNC patients treated at a single tertiary care hospital with CBS between 2016 and 2020 was performed. A multivariate Cox proportional-hazards model identified independent predictors of survival. A p value of <0.05 was considered significant. Kaplan-Meier survival analysis was performed.RESULTS:
45 patients were identified. The majority were male (80.0%) with a mean age of 64 years at time of blowout. Oropharynx was the most common primary site (48.9%) and 73.3% of patients had stage IV disease. 35 (77.7%) patients had active tumor at time of CBS. 93.3% of patients previously received RT with a mean total dose of 62.5 ± 14.8 Gy. Threatened/type I, impending/type II, and acute/type III CBS occurred in 6.7%, 62.2%, and 31.1% of cases, respectively. Patients underwent either embolization (80.0%) or endovascular stent placement (20.0%). The 30-day and 1-year OS rates were 70.1% and 32.0%, respectively. Primary oropharyngeal tumors (adjusted hazard ratio [aHR], 4.31 [1.30-15.15 95% confidence interval]), active tumor at time of CBS (aHR 8.21 [2.10-54.95]), ICA or CCA rupture (aHR 5.81 [1.63-21.50]), and acute/type III CBS (aHR 2.98 [1.08-7.98]) were independent predictors of survival.CONCLUSION:
Primary oropharyngeal tumors, active tumor at time of CBS, ICA or CCA rupture, and acute/type III hemorrhage were independent predictors of survival. Multidisciplinary management and prompt, protocol-directed intervention may improve outcomes following CBS.Palabras clave
