Outcomes of salvage surgery with free flap reconstruction for recurrent oral and oropharyngeal cancer

Objectives/Hypothesis: To evaluate outcomes of salvage surgery with free flap reconstruction for recurrent squamous cell carcinoma of the oropharynx and oral cavity with increased use of chemoradiotherapy. Study Design: Retrospective patient review. Methods: All patients undergoing salvage surgery with free flap reconstruction for oropharynx (n = 36) and oral cavity (n = 36) squamous cell carcinomas between January 2001 and January 2008 were obtained. Mean follow-up was 14 months. Previous chemoradiotherapy was used in 40% and radiotherapy alone in 60%. Results: Complications were more frequent in oropharynx than oral cavity tumors (36% and 14%, respectively; P = .05) requiring more secondary procedures (15 for oropharynx vs. six for oral cavity). Few patients returned to a normal diet (8%), and a majority retained an enterogastric feeding tube (56%). Median survival overall following salvage surgery was 44.8 months for oral cavity and 53.8 months for oropharynx head and neck squamous cell carcinoma. Overall estimated 1-, 2-, and 5-year observed survivals were 98%, 77.2%, and 43.7%, respectively. Twelve patients had a disease-free interval of
