Effects of postoperative external beam irradiation after carotid artery stripping of nodal metastasis.

Overview

PURPOSE: The objective of this study was to determine the effects of postoperative external beam irradiation (PEBI) on patients after stripping the carotid vessel of nodal metastasis. PATIENTS AND METHODS: Of 245 patients who underwent radical neck dissection for cancer of the upper aerodigestive tract between 1981 and 1995, 13 patients with nodal metastasis adherent to the carotid artery (NMCA) received a full course of PEBI after the tumor was peeled off the carotid vessel. Patterns of treatment failure, survival, and serious morbidity were evaluated. RESULTS: At the time of last follow-up (range, 3 to 125 months), fewer than half of the patients (46%) were free of disease, and two patients (15%) had developed distant metastases. The estimated 2-year survival rate was 23%. There were no intraoperative, postoperative, or post-radiation therapy complications. CONCLUSION: PEBI after carotid artery stripping of tumor can achieve locoregional disease control in select patients without an increased risk of vessel rupture. However, if the prognosis for patients with NMCA is to improve, other effective management strategies need to be investigated.
