Application of Whole-course Standardized Nutrition Management During Peri-radiotherapy in Patients With Nasopharyngeal Carcinoma After Radiotherapy: a Multicenter Randomized Controlled Clinical Study

Application of Whole-course Standardized Nutrition Management During Peri-radiotherapy in Patients With Nasopharyngeal Carcinoma After Radiotherapy: a Multicenter Randomized Controlled Clinical Study

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.

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.

Inclusion Criteria:

• Patients with nasopharyngeal carcinoma confirmed by histopathology
• Newly diagnosed patients without distant metastasis
• Age >18
• KPS ≥ 70
• Nasopharyngeal radiotherapy alone or concurrent chemoradiotherapy was planned to be received, andIMRT was used for radiotherapy
• The patient's blood counts，the lung, liver and renal functions were tolerant to radiotherapy/chemoradiotherapy（ WBC ≥ 4.0*109/L, NE ≥ 2.0*109/L, PLT 100*109/L and Hb≥ 10g/L. AST and ALT ≤ 2.5 *the upper limit（UL） ,TBIL≤1.2*the UL, CRE≤1.2* the UL, and ALP≤5* the UL）. And the ECG should be normal
• Good nutritional status,BMI:18~23Kg/ m2, PG-SGA ≤1,NRS 2002<3score
• No other previous neoplastic diseases, except for cured cervical carcinoma in situ skin basal carcinoma
