Conclusion:
Post-operative outcomes of salvage surgery for recurrent oropharyngeal squamous-cell carcinoma (OPSCC) were acceptable. Pathologic overall, T- or N-stage and patient comorbidities were the main predictors of patient clinical outcomes.
Objectives:
To evaluate post-operative outcomes of salvage surgery in patients with recurrent OPSCC and to determine their predictive factors.
Materials And Methods:
This study retrospectively reviewed the electronic medical records of all patients who underwent salvage surgery for recurrent OPSCC, between 2000-2013, in our institution. Overall survival (OS) and cause-specific survival (SS) were determined by Kaplan-Meier analysis. Predictive factors of post-operative outcomes were investigated by using univariate and multivariate analyses.
Results:
A total of 34 patients were included in this study. Local and general post-operative complication rates were 26% and 27%, respectively. A high level of comorbidity (Kaplan Feinstein Index: KFI ≥ 2) was the only factor associated with a higher risk of local (p = 0.03) and general (p = 0.04) complications. OS and SS rates at 3 years were 48% and 61%, respectively. In multivariate analysis, pathologic overall stage ≥ III was a significant predictor of OS (p = 0.02) and pathologic T-stage ≥ 3 was a significant predictor of SS (p = 0.01). Mean pre-operative and post-operative DOSS (dysphagia outcome and severity scale) scores were 4.4 and 3.9, respectively.
