Transoral robotic surgery for early T classification hypopharyngeal cancer.

BACKGROUND For hypopharyngeal cancer, transoral robotic surgery (TORS) has been reported as a new organ preserving treatment but outcomes are rarely reported. METHODS From 2010 to 2013, 10 patients with early T classification pyriform sinus cancer were selected to receive TORS and conventional neck dissection. The clinical parameters, including rates of adjuvant radiotherapy, survivals, as well as organ and function preservation, were retrospectively analyzed. RESULTS TORS was successful in all 10 patients, and 5 patients received adjuvant radiotherapy. After mean follow-up of 26 months, 1 patient died of distant metastasis and 1 patient died of other malignancy. There was no local recurrence and larynxes were all preserved. Eight surviving patients who were followed up continuously could receive oral intake and had a serviceable voice without tracheostomy or feeding tubes. CONCLUSION TORS is a feasible transoral approach for selected patients with early T classification hypopharyngeal cancer. The reported oncologic/functional outcomes are satisfactory. © 2015 Wiley Periodicals, Inc. Head Neck 38: 857-862, 2016.
