Transoral robotic surgery for residual and recurrent oropharyngeal cancers: Exploratory study of surgical innovation using the IDEAL framework for early‐phase surgical studies.

Abstract: Background: The purpose of this study was to identify the role of transoral robotic surgery (TORS) in the management of residual and recurrent oropharyngeal cancer. Methods: IDEAL (Idea, Development, Exploration, Assessment, Long‐term Follow‐up) 2a framework. Results: Of 26 patients assessed for TORS, 21 underwent the procedure, 5 underwent open resection (4 due to unsuitable anatomy/tumor extent and 1 on the basis of patient choice). Three patients underwent intraoperative ultrasound‐assisted robotic resection, and 3 received robotic‐assisted free flap inset. A technical refinement for TORS of residual and recurrent oropharyngeal cancer of the tongue base is described. Actuarial plots showed estimated overall survival of 48.2%, local control of 76.6%, and disease‐specific survival of 77.1% at 42.6 months. Conclusion: TORS is a valid management option for residual and recurrent oropharyngeal cancer. Oncologic outcomes are comparable to open surgery and transoral laser microsurgery, with the added advantages of en bloc resections, facility for intraoperative ultrasound imaging, and inset of free flaps without mandibular split.
