Background:
This systematic review aggregates the data of studies that include site-specific analyses of patients undergoing salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma.
Methods:
The primary outcomes are disease-free, disease-specific, and overall survival (DFS, DSS, and OS, respectively). Secondary outcomes include complications and postoperative feeding requirements.
Results:
Fifteen studies met the inclusion criteria with a total of 442 patients. Two-year DFS is reported from 30.0 to 50.0% and 5-year DFS ranges from 15.0 to 57.1%. Five-year DSS ranges from 28.0 to 57.1%. Two-year OS ranges from 38.8 to 52.0% and 5-year OS ranges from 15.5 to 57.1%. Complications include pharyngocutaneous fistula (0.0-71.4%), carotid artery rupture (2.9-13.3%), and stomal stenosis (4.2-20.0%). Complete oral feeding achieved following surgery ranges from 61.9 to 100.0%, while complete gastrostomy tube dependence ranges from 0.0 to 28.6%.
Conclusions:
Salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma has a relatively high complication rate and should be offered to patients with the understanding of a guarded prognosis.
