<p>The ratio of extracellular mass to body cell mass (<sc>ecm/bcm</sc>
), determined by bioelectrical impedance analysis, has been found to be a potentially useful indicator of nutrition status. Subjective global assessment (<sc>sga</sc>
) is a subjective method of evaluating nutrition status in head-and-neck cancer. The present study was conducted to investigate the association between <sc>ecm/bcm</sc>
and <sc>sga</sc>
in head-and-neck cancer.</p>
</sec>
<sec><title>Methods</title>
<p>Patients were classified as either well-nourished or malnourished by <sc>sga</sc>
