Abstract
Observational data suggests transoral surgery may offer benefit in swallowing over chemoradiotherapy. In this preliminary, non-randomized study, patients with stage III and IVA oropharyngeal carcinoma treated with transoral laser microsurgery (TLM) were assessed pretreatment and 3 months after treatment using the MD Anderson Dysphagia Inventory (MDADI), the Performance Status Scale (PSS), and a timed Water Swallow Test (WST). Comparisons were made with a historical chemoradiotherapy (CRT) cohort. Based on patients with measurements at both times, the decrease in score between baseline and 3 months was greater for CRT patients (n = 26-28) than for TLM (n = 20-21) patients for each of MDADI, PSS, and WST. A repeated measures analysis that looked at all 3 scores simultaneously and allowed for missing values gave mostly similar results (except for MDADI). TLM was associated with good early swallowing outcomes at 3 months and may offer a benefit over CRT. The results should be viewed as preliminary data, providing useful reference for any proposed controlled trial.
