MARTIN VILLARES, C. et al. Pretreatment dysphagia in advanced heat and neck cancer patients. Nutr. Hosp. [online]. 2003, vol.18, n.5, pp.238-242. ISSN 1699-5198.

Objetive: To define swallowing dysfunctions in head and neck cancer patients with respect to tumor site. Patients and methods: A consecutive cohort of 52 patients with stage III-IV head and neck cancer without prior tracheotomy or treatment were studied according to tumor site: oral cavity (n = 8), oropharynx (n = 8), hypopharynx (n = 13) and larynx (23). All patients underwent nasoendoscopy prior to treatment. Swallowing function (dysphagia, aspiration and Swallowing Performance Status Seale score) was analyzed with reference to tumor localization using χ2and Fisher exact tests. Results: Laryngeal and hypopharyngeal neoplasms neoplasms showed the most severe pre-treatment swallowing dysfunction (27% pre-treatment vs. 11% post-treatment), and oral and oropharyngeal neoplasms showed the most severe post-treatment swallowing dysfunction (6% pretreatment vs. 68% post-treatment). Aspiration and tumor localization revealed not statistically significant differences between groups. Pre-treatment dysphagia did not correlate with post-treatment dysphagia. Conclusions: Laryngeal and hipopharyngeal neoplasms showed severe pre-treatment swallowing dysfunctiona and oral and oropharyngeal neoplasms showed severe post-treatment swallowing dysfunction.
