Background
For primary organ preservation, concurrent chemoradiotherapy (CCRT) is performed for advanced squamous cell carcinoma of the head and neck (SCCHN). In this organ-preservation setting with CCRT, surgery is reserved as a salvage treatment in cases of locoregional failure after CCRT. The purpose of the study was to review our experience with salvage surgery after CCRT for patients with SCCHN and to evaluate the effectiveness and prognostic factors affecting survival.
Methods
The records of patients with stage II-IVB SCC of the larynx, oropharynx, or hypopharynx treated with salvage surgery after CCRT between 1998 and 2012 were reviewed.
Results
A total of 645 patients with previously untreated, resectable SCC of the larynx, oropharynx, or hypopharynx received CCRT. Salvage surgery was performed for 78 of 225 patients with residual or recurrent tumors. The 5-year overall survival (OS) and disease-specific survival rates for patients who received salvage surgery were 61.0 and 65.5 %, respectively. Stage IV, poorly differentiated, synchronous double cancer, and surgical complications were significant predictors of unfavorable OS on multivariate analysis. Postoperative complications were observed in 30 patients (38.5 %).
Conclusions
Salvage surgery is the best therapeutic option for failure after CCRT for SCCHN because of its good survival rate, although a high surgical complication rate is seen. Patients with initial stage IV tumors, poorly differentiated SCC, or synchronous double cancer are considered for further adjuvant treatment.
