Abstract

Background: The purpose of this study was to present our evaluation of the outcome of oropharyngeal cancer managed with neoadjuvant chemotherapy and transoral surgery (TOS) with neck dissection as definitive treatment.

Methods: This is a case series of 17 patients with advanced oropharyngeal cancer who were treated with neoadjuvant chemotherapy followed by TOS. The treatment details and oncologic outcome are reported. The volumetric response of the tumor to neoadjuvant chemotherapy is evaluated and validated by histopathology.

Results: Seventeen patients with TNM stages III and IV oropharyngeal cancer constitute this series for survival analysis. On a median and mean follow-up of 31 and 40 months, respectively, 16 of the 17 patients were alive without recurrence. Disease-specific survival (DSS) and overall survival (OS) at 3 years were 94.1%.

Conclusion: Adjuvant chemotherapy followed by TOS and neck dissection is a feasible and efficacious novel therapeutic approach for definitive management of moderately advanced oropharyngeal cancer, reserving radiotherapy (RT) for salvage or adverse features. © 2016 Wiley Periodicals, Inc.
