Objective To evaluate the long-term effects on swallowing function of concomitant continuous infusion hydroxyurea and hyperfractionated radiation therapy used to treat advanced head and neck carcinoma.
Design A prospective evaluation of swallowing function was performed on an inception cohort by analyzing posttreatment videoflouroscopic swallow function studies using radiological descriptors for pharyngeal transport abnormalities and temporal measures of structural movements, as well as by conducting patient interviews to assess alimentation, more than 1 year after tumor treatment (range, 52-124 weeks; median, 70 weeks).
Setting Academic tertiary care referral medical center.
Patients Ten patients, aged 44 to 71 years, with stage III and IV squamous cell carcinoma of the oral cavity, oropharynx, or hypopharynx.
Main Outcome Measure Radiographic and temporal swallow abnormalities, as well as functional status, were documented and compared with published norms and results of earlier swallowing studies when possible.
Results Pharyngeal transport dysfunction and anterior segment abnormalities, manifested by epiglottic dysmotility, vallecular residue, laryngeal penetration, or aspiration, were evident in all 10 patients. Posterior segment abnormalities, such as pharyngeal stasis, constrictor dysmotility and piriform residue were documented in 8 patients. Three patients developed late aspiration, and the majority of patients showed persistent or worsened delay in laryngeal movement compared with their earlier posttreatment evaluations. Also, 3 patients developed a hypopharyngeal stricture, and 6 patients continued to require gastrostomy tube supplementation beyond 1 year. There was no association between site of primary, duration to swallowing evaluation, and severity of dysfunction.
Conclusion Prolonged and debilitating functional swallowing abnormalities may occur after this aggressive concomitant chemotherapy and radiotherapy regimen.
