Impact of Oral Nutrition Supplements in Gastrointestinal Cancer Patients: A Randomized Controlled Trial

<b>Background</b>: Malnutrition is a significant national health problem in countries with low and intermediate incomes and was announced in the United Nations' 2030 Agenda for Sustainable Development Goals. Chemotherapy may have adverse effects on nutritional health issues and quality of life experience, particularly in patients with gastrointestinal (GIT) cancer. Our research's objective was to determine the beneficial effects of oral nutrition supplements on nutritional status assessed by maintenance of whole-body composition and patient-generated subjective global assessment (PG-SGA) in all GIT cancer patients treated with chemotherapy medications. <b>Methods</b>: Among the patients, the nutrition support (NS) group (<i>n</i> = 75) received 500 kcal daily of a balanced oral nutrition supplement formula for 12 weeks, while the control (C) group (n = 75) did not. Anthropometric measures, whole-body composition, nutritional status biomarkers, and the PG-SGA questionnaire were assessed. Additionally, this study analyzed whole-body composition, skeletal mass, fat mass, laboratory data, the complete lipid profile, albumin, total protein, adverse effects, and therapy delays. <b>Results:</b> After 12 weeks, the NS group showed a significant increase in body weight, with a mean difference of 1.27 ± 3.39, while the C group showed a mean difference of only 0.15 ± 0.42. Moreover, fat mass increased in the NS group, showing a mean difference of 0.55 ± 3.69, while the C group showed a fat mass loss with a mean difference of -0.21 ± 2.93. The fat mass index (FMI) indicated statistical significance between the two groups. There was a statistically significant difference in the lean mass index between the two groups, favoring a steady increase in the NS group. The NS group showed improvements in the PG-SGA and nutritional biochemical markers, such as albumin. The initial findings from our study include data from a total of 150 patients, including 75 patients in the NS group and 75 patients in the C group. These results are consistent with earlier research. <b>Conclusions:</b> Early oral nutrition supplements for GIT cancer may enhance nutritional outcomes and reduce the delay of disease-related therapy. Additionally, they may help maintain body composition.
