Results of Total Laryngectomy as Treatment for Locally Advanced Hypopharyngeal Cancer

Abstract

Introduction and objectivesTotal laryngectomy (TL), with eventual postoperative radiotherapy, has proven to be effective in treating cases of locally advanced hypopharyngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with hypopharyngeal cancer classified T3 and T4. MethodsWe studied 59 patients (33 T3 and 26 T4a) with primary squamous cell carcinoma of the hypopharynx treated with TL from 1998 to 2012. ResultsMean age was 61 years with a male predominance (96.6%). All the patients were smokers and 96% consumed alcohol. Unilateral selective neck dissection (ND) was performed in 12 patients, unilateral radical ND in 11 patients, bilateral selective ND in 20 patients and radical ND plus selective ND in 14 patients. Sixty-six percentage of the patients received postoperative radiotherapy. Lymph node metastases occurred in 81% of the patients and extranodal invasion in 56% of them. Twenty-nine percentage of the patients had loco-regional recurrence, 17% developed distant metastases, and 25% a second primary tumour. The 5-year disease-specific survival was 46%. ConclusionsTL extended to pharynx (with eventual postoperative radiotherapy) offers good oncological results in terms of loco-regional control and survival in locally advanced hypopharyngeal cancer, so organ preservation protocols should achieve similar oncological results to those shown by TL.
