Conclusion: Surgical treatment of carotid invasion may give an improved 2-year survival in selected patients without significant morbidity.
Objective: To evaluate survival outcomes in patients with head and neck squamous cell carcinomas invading the carotid artery.
Patients and methods: At the time of carotid invasion, 23 patients underwent surgery (n=11), chemoradiotherapy (n=6), or palliation (n=6). Surgical methods included carotid resection and ligation (n=5), carotid resection and reconstruction with saphenous vein (n=4), and peeling (n=2). Survival outcomes among different treatments were compared.
Results: None of the 11 surgical patients experienced perioperative mortality or major neurologic complications. Three of these patients survived, but two had recurrent disease at last follow-up; their 2-year overall survival and disease-free survival rates were 24.5% and 18.2%, respectively. In contrast, all patients treated with chemoradiation or palliation died within 15 months. Median survival time was 16.5 months in the surgery group, 11.5 months in the chemoradiation group, and 3 months in the palliation group (p=0.025).
