Dysphagia after chemoradiation: analysis by modified barium swallow.

Objectives: We sought to describe the findings of modified barium swallow study after chemoradiation in patients with head and neck cancer and to correlate these findings with clinical variables, including gastrostomy tube dependence and clinical pneumonia.

Methods: We retrospectively reviewed 49 patients at a tertiary care center who underwent modified barium swallow study for dysphagia after chemoradiation.

Results: Patients with nonlaryngeal lesions had increased cricopharyngeal impairment (27.8% versus 0.0%; p = .04). Patients who underwent concomitant chemotherapy had increased epiglottic changes relative to those who had radiotherapy alone (66.7% versus 30.8%; p = .05). Clinical pneumonia developed in 31.9% of the patients, and 79.6% required gastrostomy tube placement for a mean duration of 18.1 months.

Conclusions: Chemoradiation effects deglutition at multiple levels. A large percentage of patients will develop pneumonia and feeding tube dependence. This study is among the largest to correlate the results of modified barium swallow studies to clinical variables in this patient population. This study highlights the significant incidence of gastrostomy tube dependence and pneumonia in these patients.
