description Objective: Determine prevalence of viable malignancy in patients undergoing neck dissection (ND) for residual neck disease following concomitant chemotherapy and irradiation (chemo/xrt) for upper aerodigestive squamous carcinoma. To determine survival in groups with a neck complete response to those who had residual disease requiring neck dissection. Study Design: Retrospective chart review. Methods: Retrospective chart review of 230 patients who underwent definitive chemo/xrt for primary squamous cell carcinoma cancer (SCCa) of the head and neck from 2005 to 2009 in one institution. Results: Thirty‐nine (17%) patients underwent ND for residual neck mass within 4 months posttreatment. Forty‐nine percent (19/39) were pathologically positive for malignancy and 51% (20/39) were negative. The probability of a +ND based on original N‐stage was not statistically significant (P = .368). Primary site did not yield significant probability of having +ND, except in the oral cavity (P = .02). Patients had similar overall 5‐year survival, among those with a delayed complete response in the neck (66%), ND for residual disease (71%), or those with initial complete response (71%). Lower initial N‐stage demonstrated improved survival in all outcome groups. Tonsil SCCa patients who underwent ND had improved survival compared to those with delayed complete response (87.5 vs. 75.8%), both of which had increased survival compared to initial complete responders (65%). Conclusions: This study supports the use of ND in the postchemo/xrt positive neck regardless of primary site or initial N‐stage. ND in this setting conveys survival equal to patients with complete response in the neck after chemo/xrt. These survivorship implications of postchemo/xrt neck dissection extend to all sites, including tonsils.
