Abstract
We reviewed the swallowing function of 64 patients after surgery with advanced oropharyngeal cancer at our hospital between 2007 and 2016. There were 57 men and 7 women, aged 44-88 years (median: 63). The observation period was 12-96 months (median: 24 months), p16 positive in 46 cases and p16 negative in 18 cases, and the clinical stage was as follows: Stage Ⅲ, 14 cases; Stage ⅣA, 48 cases; Stage ⅣB, 2 cases. There were 30 cases with postoperative radiation therapy (PORT). We assessed the swallowing function using the Functional Oral Intake Scale (FOIS) score. High age, p16 negative, resection including root of tongue and PORT were independent factors in poor swallowing function with multivariate analysis and cases with PORT showed no improvement in FOIS score at 12 months.
