Tolerability,Toxicity,and Temporal Implications of Transoral Robotic Surgery (TORS) on Adjuvant Radiation Therapy in Carcinoma of the Head and Neck

Abstract

Objectives:

Overall treatment package time (from surgery to radiotherapy [RT] completion) > 100 days can portend poor outcomes in head and neck cancer. Faster postoperative recovery seen with transoral robotic surgery may decrease treatment duration and toxicity for adjuvant RT and chemoradiation.

Methods:

We retrospectively reviewed all patients treated with transoral robotic surgery (n = 124) and adjuvant RT and chemoradiation (n = 33) at our institution for head and neck cancer from April 2007 to December 2011 to determine treatment duration, acute toxicity, and long-term percutaneous gastric tube rates.

Results:

The median overall treatment time was 86 days and from surgery to RT start was 41 days; median RT duration was 44 days. No wound breakdown or infection occurred during or after RT. Two-year actuarial locoregional control, distant metastasis–free survival, and overall survival rates were 93%, 96%, and 97%, respectively.

Conclusions:

Adjuvant RT after transoral robotic surgery for head and neck cancer can be completed safely and in a timely fashion. Longer follow-up and a larger cohort will be needed to determine if this regimen is more effective than traditional surgery followed by adjuvant RT.
