To evaluate the effectiveness of selective neck dissection in patients with nodal metastases from head and neck squamous cell carcinoma.Historical cohort study.Academic medical center.A chart review was performed on 156 subjects with clinically positive regional nodal metastases managed initially with surgery, including neck dissection. Sixty-nine subjects underwent selective neck dissection (less than 5 levels), and the majority received postoperative radiotherapy (80%). Primary outcomes included Kaplan-Meier three-year ipsilateral regional control and five-year overall survival. Cox proportional univariate and multivariate analyses were performed to determine those factors associated with outcome.There were two ipsilateral regional recurrences among those undergoing selective neck dissection, yielding a regional control rate of 95.9 percent. Among those undergoing comprehensive neck dissection, nine ipsilateral regional recurrences occurred, yielding a control rate of 86.0 percent (P = 0.053). No selective neck dissection recurrences occurred in a preserved level. Selective neck dissection, as compared to comprehensive neck dissection, was not adversely associated with regional recurrence, survival, or distant metastasis, even after adjusting for possible confounders (hazard ratio 0.21, P = 0.055).These results demonstrate high rates of regional disease control (96%) following selective neck dissection and radiotherapy in patients with positive neck node metastases. In this population, performing selective neck dissection with adjuvant radiotherapy for the majority of patients is supported as an effective treatment approach.
