Surgical treatment for hypopharynx carcinoma: feasibility, mortality, and results

Abstract

This study seeks to evaluate treatment modalities, mortality after surgery, survival, and local control rates for a consecutive cohort of patients with cancer of the hypopharynx treated according to a prospective protocol that favors surgery as an initial approach to the disease. The charts of 228 consecutive patients with previously untreated hypopharyngeal squamous cell carcinoma were reviewed. Outcome measures (overall survival, disease specific survival, and local control) were calculated using the Kaplan-Meier estimator. Of 228 consecutive patients, 136 (59.6%) were found suitable for initial surgical treatment. Of the remaining 92 patients, 18 (7.9%) had nonresectable lymph node metastases, 16 (7.0%) had unresectable primary tumors, 13 (5.7%) refused surgery, and 13 (5.7%) presented distant metastases during initial diagnostic evaluation. Of those who had surgery, 46 had larynx-sparing procedures, 54 had total laryngectomy, and 36 had total laryngo-pharyngectomy. None of the patients who had surgery died postoperatively. Actuarial 5-year overall survival was 27.2% for all 228 patients, 39.5% for the 136 patients with surgical treatment, and 61.1% for the 46 patients who were treated with larynx-sparing procedures.
