Salvage surgery for recurrence of laryngeal and hypopharyngeal squamous cell carcinoma: A retrospective study from 2005 to 2013

Salvage surgery for laryngeal or hypopharyngeal cancer is difficult, and survival is not good. Laryngeal primary and recurrence location, moderate tumor volume and extension (< T4), prior chemotherapy and neck dissection during salvage surgery were associated with better overall and disease-free survival, which should enable better patient selection.
