BACKGROUND: The purpose of this study was to quantify the association of late lower cranial neuropathy (late LCNP) with swallowing-related quality of life (QOL) and functional status among long-term oropharyngeal cancer (OPC) survivors. METHODS: Eight hundred eighty-nine OPC survivors (median survival time: 7 years) who received primary treatment at a single institution between January 2000 and December 2013 completed a cross-sectional survey (56% response rate) that included the MD Anderson Dysphagia Inventory (MDADI) and self-report of functional status. Late LCNP events ≥3 months after cancer therapy were abstracted from medical records. Multivariate models regressed MDADI scores on late LCNP status adjusting for clinical covariates. RESULTS: Overall, 4.0% (n = 36) of respondents developed late LCNP with median time to onset of 5.25 years post-treatment. LCNP cases reported significantly worse mean composite MDADI (LCNP: 68.0 vs no LCNP: 80.2; P < .001). Late LCNP independently associated with worse mean composite MDADI (β = -6.7, P = .02; 95% confidence interval [CI], -12.0 to -1.3) as well as all MDADI domains after multivariate adjustment. LCNP cases were more likely to have a feeding tube at time of survey (odds ratio [OR] = 20.5; 95% CI, 8.6-48.9), history of aspiration pneumonia (OR = 23.5; 95% CI, 9.6-57.6), and tracheostomy (OR = 26.9; 95% CI, 6.0-121.7). CONCLUSIONS: In this large survey study, OPC survivors with late LCNP reported significantly poorer swallowing-related QOL and had significantly higher likelihood of poor functional status. Further efforts are necessary to optimize swallowing outcomes to improve QOL in this subgroup of survivors.
