Patients with locally advanced hypopharyngeal carcinoma. Results over a 30-year period

© 2018 Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello Introduction and objectives: The treatment of locally advanced carcinomas of the hypopharynx may include surgery or several combinations of radiotherapy and chemotherapy as organ preservation strategies. The objective of the present study is to analyze the results of locally advanced hypopharyngeal carcinoma patients treated in a single centre over a 30-year period. Methods: Retrospective chart review of 278 patients with T3-T4 hypopharyngeal carcinomas treated between 1985 and 2015 at a tertiary institution. Results: As much as 15.5% of the patients received only palliative treatment. Surgery, usually followed by radiotherapy or chemoradiotherapy was offered to 38.1% of the patients, and radiotherapy or chemoradiotherapy alone was offered to the remaining 46.6% of the patients. Cause-specific survival at 5 years was 39.7% (95% CI 33.7-45.7) for the whole sample. Surgery achieved better local control of the disease, but these figures did not translate into an increase of cause-specific survival for T3 tumours. Five-year survival free of laryngeal dysfunction for patients who received conservative treatment was 36.4%. In a multivariate analysis, only T4 local extension, N2-3 category, and posterior hypopharyngeal wall location related significantly with cause-specific survival. Conclusions: There were no significant differences in cause-specific survival related to treatment modality for T3 carcinomas. On the other hand, surgery achieved a significant increase in cause-specific survival for T4 hypopharyngeal carcinomas.
