Analysis of nutritional risk factors in esophageal cancer after concurrent chemoradiotherapy / 重庆医学

ABSTRACT

Objective To explore the nutritional increased risk related factors in esophageal cancer patients after chemoradio‐therapy .Methods Sixty‐eight esophageal cancer patients undergoing concurrent chemoradiotherapy were prospectively investiga‐ted .The patient‐generated subjective global assessment(PG‐SGA) was adopted to grade the nutritional risk .All of the patients re‐ceived early nutrition education and short‐term nutrition support for severe malnutrition ,nutritional status was assessed again at the end of radiotherapy .The patients were divided into the mild‐to‐moderate malnutrition group[PG‐SGA(B)group] and the severe malnutrition group [PG‐SGA(C)group] according to the PG‐SGA score on admission .The body mass ,albumin(Alb) ,hemoglobin (Hb) ,white blood cells ,platelets ,neutrophils ,lymphocytes ,monocytes and other objective nutrition indicators were collected before and after chemoradiation .Results There were 24 cases in the PG‐SGA(B) group and 44 cases in the PG‐SGA(C) group;the gen‐der ,age and ethnic had no statistical differences between the two groups(P>0 .05) .Hb(χ2 =2 .710 ,P=0 .009) and Alb(χ2 =3 .743 ,P=0 .000) before chemoradiotherapy had no statistical difference between the two groups(P>0 .05);Hb and Alb after che‐moradiotherapy in the PG‐SGA(B) group were higher than those in the PG‐SGA(C) group .The body mass index(BMI)before and after chemoradiotherapy had statistically significant difference between the two groups (P<0 .05) .The percentage of body mass decrease in the two groups had no statistical significance (P=0 .487) .The PG‐SGA scores after chemoradiotherapy were positively correlated with the change of Hb ,Alb ,BMI parameters and percentage of weight decrease before and after chemoradiotherapy(rs=0 .240 ,0 .249 ,0 .282 ,0 .447 ,P<0 .05) .Conclusion The poor understanding of malnutrition ,the change of Hb ,Alb ,BMI parame‐ters and percentage of body weight decrease before and after chemoradiotherapy are the nutritional increased risk factors in esopha‐geal cancer patients after chemoradiotherapy .
