OBJECTIVES/HYPOTHESIS Head and neck squamous cell carcinoma (HNSCC) has a high tendency for regional lymphatic spreading. Nevertheless, isolated regional lymph node recurrences are rare, and only limited data regarding its management are available. The aim of this study was to describe treatment modalities and outcomes, and to identify prognostic factors. Study Design Retrospective cohort study. METHODS The records of all patients (n = 498) with tumor persistence or recurrence after curatively intended treatment for HNSCC were retrospectively reviewed. Patients with synchronous secondary tumors at initial presentation, tumor persistence, local or locoregional recurrence, and systemic metastases were excluded. RESULTS A total of 76 patients were included. The rate of occult additional metastasis in radiologically uninvolved neck compartments during salvage neck dissection was 25%. The salvaged patients showed a 37.5% 5-year recurrence-free survival (RFS). Multivariate analysis revealed initial stage IVA-B (hazard ratio [HR]: 4.16, P < .01), extracapsular spread (HR: 3.71, P = .04), higher involved/total lymph node ratio (HR: 6.79, P < .01), and soft-tissue infiltration (HR: 3.27, P < .01) as independent adverse prognostic factors for RFS. Moreover, univariate data analysis identified recurrent stage rcN2-3; clinical involvement of the neck levels IV, V and/or VI; and smoking as adverse risk factors for RFS. CONCLUSIONS This study identifies initial stage IVA-B, extracapsular spread, higher involved/total lymph node ratio, and soft-tissue infiltration as independent adverse prognostic factors for RFS following isolated regional recurrences. The incidence of occult additional metastasis of radiologically uninvolved levels during salvage neck dissections was high (25%). Therefore, superselective or selective neck dissection would not have been the adequate type of salvage surgery. LEVEL OF EVIDENCE 4 Laryngoscope, 2020.
