RESUMO
OBJECTIVE: Salvage surgery has a higher complication rate compared to primary surgical treatment. We evaluated clinical outcome of salvage neck dissections in relation to initial treatment modality, extent of surgery and patient-related factors. DESIGN: Single institution consecutive case series. SETTING: Tertiary Head and Neck Cancer Centre. PARTICIPANTS: In all, 87 patients with head and neck squamous cell carcinoma, who underwent salvage neck dissection after initial radiotherapy (n = 30), radiotherapy with carboplatin/5-fluorouracil (n = 43) or radiotherapy with cetuximab (n = 14). MAIN OUTCOME MEASURES: Incidence of complications, disease-specific survival. RESULTS: Complications occurred in 28% of the patients. Multivariate analysis identified extent of neck dissection as the only independent predictor of surgical complications (P = 0.010). Surgical complication rate was 16% after radiotherapy with systemic treatment, and 47% after radiotherapy alone (P = 0.171). The 5-year disease-specific survival was 55%, independent of complications, initial treatment, extent of surgery and patient-related factors. CONCLUSION: The only predictor for surgical complications was extent of surgery. Survival was not influenced by complications.
