title: Functional outcomes after organ preservation treatment in head and neck cancer: a critical review of the literature.
abstract: The use of radiation therapy and/or chemotherapy in advanced head and neck cancer is increasing in popularity, driven by the notion that sparing the organs of speech and swallowing from surgical resection will also spare function. This critical review of the literature considered functional outcomes after organ preservation to assess the impact of such treatment on speech, swallowing and quality of life in patients with head and neck cancer. Literature searches were conducted on several library databases. A total of 50 relevant articles were identified and found to meet the inclusion criteria specified a priori. The majority of reports suggested that organ preservation techniques have the potential to result in swallowing disorders, often related to dysmotility of the oropharyngeal and laryngeal structures, and resulting in frequent episodes of aspiration. This may lead to the need for enteral feeding in the short term for some patients while, in others, this need is life long. Speech does not appear to be affected to the same degree as swallowing. These results suggest that organ preservation does not translate into function preservation for all patients with head and neck cancer.
