Functional and quality-of-life outcomes of transoral robotic surgery for carcinoma of unknown primary.

OBJECTIVES/HYPOTHESIS To determine speech, eating, aesthetics, social disruption, and overall quality-of-life outcomes over a year period in patients who underwent transoral robotic surgery as part of carcinoma of unknown primary diagnosis and treatment. STUDY DESIGN Observational prospective study. METHODS Twenty-two patients who underwent transoral robotic surgery for the management of carcinoma of unknown primary were included. Patients prospectively completed the Head and Neck Cancer Inventory during a preoperative visit, and at 3-week, 3-month, 6-month, and 12-month postoperative visits. Patients' demographic, pathological, and follow-up information were also collected. RESULTS The mean follow-up time was 19.8 months. There were overall declines in all quality of life scores during treatment period, which was followed by a continuous recovery. The scores immediately after transoral robotic surgery (3 weeks) were significantly higher than the scores after conclusion of adjuvant therapy (3 months) in multiple domains (P < .05) and the 6-month scores in speech (P = .02) and eating (P = .008) domains. All scores, except for eating (P = .01) returned to pretreatment levels at 1 year. Patients with detected primaries displayed similar quality-of-life scores compared to patients with occult primaries. Human papillomavirus status and type of adjuvant treatment had no significant impact on quality of life. CONCLUSIONS Transoral robotic surgery is a promising, minimally invasive procedure for the surgical management of carcinoma of unknown primary. Patients maintain high functional and quality-of-life status at 1 year after surgery.
