Tracheostomy dependence following "organ preservation" (chemo)radiation protocol for laryngeal and hypopharyngeal cancers.

BACKGROUND: Patients receiving primary (chemo)radiotherapy for laryngeal or hypopharyngeal cancer risk developing severe laryngeal dysfunction and becoming tracheostomy dependent, detracting from the benefits of organ preservation. We aim to describe the airway outcomes for this cohort and identify risk factors for developing tracheostomy dependence. METHODS: Patients with laryngeal or hypopharyngeal cancer who were recommended for and underwent primary (chemo)radiotherapy over a 6-year period were identified from a tertiary hospital Head and Neck cancer database. Patient, tumor, and treatment details were collected and analyzed. RESULTS: Of 166 patients, 18.7% (N = 31) required tracheostomy insertion. Advanced tumor classification was the only significant predictor (p < 0.00001). Successful decannulation was observed in 12.9% (N = 4). Decannulation was observably less successful with advanced tumors, bilateral vocal cord immobility, tracheostomies inserted under emergency conditions. CONCLUSION: We quantified tracheostomy insertion rates and dependence in patients undergoing "organ-preserving" (chemo)radiotherapy, to assist in the pre-treatment counseling of patients opting for this approach.
