Abstract
Objective To evaluate the risks of malnutrition and nutritional status of patients with esophageal cancer during radiotherapy , so as to explore nursing countermeasures to improve their nutritional status.Methods 60 inpatients with esophageal cancer receiving routine radiotherapy from June 2012 to April 2013 were investigated with anthropometric indicators and laboratory data for weekly nutritional evaluation on admission, during radiotherapy, and after radiotherapy.Meanwhile, the patients were conducted with Nutritional Risk Screening （ NRS2002 ） per week .Results NRS2002 score showed that the malnutrition risk values of patients with esophageal cancer gradually increased after radiotherapy .The score was （2.06 ±177;1.22） after 2 weeks of radiotherapy, suggesting that the difference was statistically significant （t=-2.457, P<0.05）. After the radiotherapy , the scores of body mass index （ BMI ） , triceps skinfold （ TSF ） , arm circumference （AC）, total protein （TP）, albumin （ALB） and total lymphocyte count （TLC） were （20.21 ±177;2.69）kg/m2, （7.27 ±177;3.20）mm, （24.71 ±177;2.68）cm, （65.50 ±177;5.25）g/L, （38.48 ±177;5.00）g/L and （6.55 ±177;3.42） ±215; 109/L, respectively, compared with those of admission , they decreased gradually in the subsequent weekly examinations and had statistical significance （ t=3.204,2.777, 3.053,7.174,5.685,12.508, respectively;P<0.05）.After 2 weeks of radiotherapy, the incidence of malnutrition increased compared to that of admission, and the scores of TSF, TP and TLC were 95.00%, 11.67% and 98.33% respectively, which showed the statistically significant difference （χ2 =11.800, 7.792, 73.024, respectively; P <0.05 ）. Conclusions Patients with esophageal cancer gradually have higher risk of malnutrition and worse nutritional status during radiotherapy and their incidence of malnutrition increased after 2 weeks of radiotherapy .
