Functional outcomes in head and neck cancer.

For advanced head and neck cancer (HNC) patients, the effects of disease and the side effects of aggressive treatments have the potential to severely affect function and quality of life. More recent treatment strategies offer patients many options and have increased rates of locoregional control. However, they have not eliminated either acute treatment side effects or the spectrum of negative late sequelae, such as eating and speech dysfunction, residual pain, and troublesome dryness of the mouth. Understanding this broad spectrum of side effects and how patients experience them as well as the functional and quality of life implications is important to treatment evaluation and patient decision making. The heterogeneity of HNC patients (in terms of tumor site), the diversity of surgical techniques and chemoradiotherapy regimens, together with individual patient differences in response to these variables, make it particularly difficult to describe precise outcomes attached to various treatment options. However, in the context of this caveat, there are increasing data documenting the impact of various treatment modalities on physical, functional, and QOL outcomes. This article presents some of these data with a focus on the performance and functional results of radiation therapy, surgery, or concomitant chemoradiation therapy.
