Metabolic abnormalities associated with weight loss during chemoirradiation of head-and-neck cancer

Conclusions: Weight loss during cisplatin-containing chemo-RT was found to be associated with reduced kidney function. These findings do not establish cause-effect relationships; however, they highlight the importance of intensive supportive measures of nutrition and hydration beyond standard hydration during cisplatin administration. These intensive measures should be enacted before a 10% weight loss is reached.
