Association of nutritional status and functional capacity in gastrointestinal cancer patients

To determine the nutritional status and its association with functional capacity in patients with digestive tract cancer.

We retrospectively studied all adult patients hospitalized who were diagnosed as having a cancer of the digestive tract. Nutritional status and functional capacity were assessed. Descriptive statistic and odds ratio were used to determine the association in SPSS 14.0.

57 patients were included, 96% had weight loss. Using subjective global assessment (SGA) as a method of screening, 82.5% of the patients were found malnutrition and by biochemical and immunological test 82% and 65% respectively. Functional capacity was assessed by Karnofsky index, finding that 75.5% of the patients have some activity limitation. Results show an association between malnutrition by SGA and limitation in functional capacity (c2 = 1.56; p = 0.212; OR: 2.46; 95% confidence interval [95% CI]: 0.581-10.465). In addition, we observe an association between the total lymphocyte count and limitation in functional capacity (χ2 = 6.94; p = 0.008; OR: 5.23; 95% CI: 1.441-19.025).

Malnutrition in patients with digestive tract cancer was associated with limitation in functional capacity.
