BACKGROUND: Planned neck dissection after chemoradiotherapy (CRT) has remained controversial in advanced oro- and hypopharyngeal squamous cell carcinoma (OHSCC) patients. We evaluated the survival contribution of neck dissection (ND) in OHSCC patients with residual nodal disease following CRT. METHODS: We retrospectively evaluated 84 OHSCC patients with N2-3 disease treated at Aichi Cancer Center Hospital between 1995 and 2006. ND after CRT was performed for residual neck disease in 36 patients, but not in 48 patients to achieve a complete response. These two groups were analyzed in terms of both overall survival (OS) and regional control (RC), and surgical complications were evaluated. RESULTS: The 5-year OS was 76.7 % [95 % confidence interval (CI) 58.8-87.6] for the ND group and 73.9 % (58.6-84.3) for the non-ND group (P = 0.883). The 5-year RC was 91.6 % (76.1-97.2) for the ND group and 81.1 % (65.4-90.2) for the non-ND group (P = 0.252). Stratified by primary tumor site, the 5-year RC was 96.3 % (76.5-99.5) for the ND group, and 78.6 % (58.0-89.9) for the non-ND group (P = 0.072) in oropharyngeal squamous cell carcinoma patients, and 77.8 % (36.5-93.9) for the ND group and 85.9 % (54.0-96.3) for the non-ND group (P = 0.541) in hypopharyngeal squamous cell carcinoma patients. In addition, the complications after ND were tolerable. CONCLUSIONS: We demonstrated that ND was feasible, safe, and correlated with clinical outcomes in OHSCC patients with residual nodal disease after CRT.
