In this study, nutrition intervention was performed in one group of nasopharyngeal carcinoma patients with no nutritional risk during the periperiod of radiotherapy , and the other group with no additional intervention when without nutritional risks, for evaluating the value of overall nutritional management in the periperiod radiotherapy.
This study will present an advanced equipment of tumor nutrition diagnosis and assesment for nasopharyngeal cancer(NPC) radiotherapy patients in nutritional risk screening, evaluation, diagnosis and directing nutritional intervention, aiming to explore the advantages of the whole nutritional management in acute radiation reaction rate, completion rate of radiotherapy, nutritional status, and quality of life for NPC patients.
