Abstract

Objectives: To investigate the effect of external beam radiotherapy (EBRT) for head and neck cancer (HNC) the intimal-medial thickness (IMT) and the lumen of the carotid artery.

Methods: Patients with HNC and an indication for EBRT were enrolled. A carotid artery color Doppler examination was performed before and 6 and 12 months after EBRT.

Results: From 2008 to 2011, 50 patients were enrolled. The mean carotid IMT was 0.9 vs. 1.02 mm before and 6 months after EBRT, respectively (p = 0.0001). The common carotid artery lumen was narrowed without statistical significance, 6 months after EBRT (p = 0.3). 1 year from EBRT, the IMT increase and the lumen reduction were statistically significant (p = 0.001, p = 0.01, respectively). Neurological events (stroke or TIA) were not observed.

Conclusions: Our data showed a significant IMT increase 6 months from EBRT without a corresponding narrowing of the common carotid lumen while a significant increase 12 months after EBRT.
