Prevalence and Predictors of Malnutrition in Nasopharyngeal Carcinoma.

Abstract

We assessed the prevalence and predictors of malnutrition in patients with nasopharyngeal carcinoma. Sixty cases and 123 controls matched for age and gender were included. Bio-data, dietary history, height, weight, body mass index (BMI), ideal body weight, and serum albumin levels were recorded. Pretreatment weight loss of >5% was present in 35% of subjects (P < 0.0001). A BMI of < 18.5 kg/m2 was present in 13.3% (P < 0.001), percent ideal body weight of <90% was present in 30% (P < 0.001), and serum albumin levels <30 g/dL was present in 23.3% (P < 0.001) of cases. Nasopharyngeal carcinoma increased the likelihood of having a BMI < 18.5 kg/m2 (odds ratio, 9.3 (3.4–25.3) P ≤ 0.001). Logistic regression shows that stage IV disease was associated with a decrease in all parameters except protein-calorie intake. Stage IV nasopharyngeal carcinoma is a predictive marker for weight loss and low serum albumin levels. Nutritional management is important for ensuring the patients’ ability to withstand chemoradiation and thus improve survival and quality of life.
