Abstract
INTRODUCTION: Malnutrition is common among patients undergoing surgery for cancer. ONS is usually prescribed but more evidence for the intervention is needed. This study aimed to assess ONS effect on body weight, energy, protein and micronutrients intake. METHODS: Newly diagnosed adult colorectal cancer patients (N=30) at risk for malnutrition and scheduled for surgery were randomized into two groups. The ONS group consumed two packs/day of ONS in addition to their usual diet, 7-14 days preoperatively and continued postoperatively when oral feeding resumed. The control group continued with their diet without ONS. Both groups received dietary counselling. Diet and ONS consumption, antropometric parameters, patient-generated subjective global assessment score, hand grip strength, serum albumin and transthyretin were determined at baseline, a day before surgery, and postoperative day seven. Repeated measures ANOVA were employed to look at changes within and between groups. RESULTS: ONS group showed less weight loss postoperatively (ONS group - 0.0±0.7 kg, control group -3.1±0.6 kg (p<0.05). Preoperatively, the energy intake increased in the ONS group (576±108 kcal/day, p<0.05) whereas the control group showed a decline (-188±106 kcal/day, p<0.05). Postoperatively, the decline in energy intake continued in both groups (ONS group -276±194 kcal/day, p>0.05; control group -585±187 kcal/day, p<0.05). Similar trend in protein intake was observed. DISCUSSION: ONS supplementation reduced weight loss and optimized nutrients intake preoperatively before the onset of surgical trauma. However, a more comprehensive study is required to confirm the findings.
