Forty-five patients with various
malignancies of the gastrointestinal tract had their nutritional status assessed pre-operatively to determine the prevalence of
malnutrition and to establish the correlation of
malnutrition with post-operative outcome. Ten nutritional parameters were assessed. Based on these markers, we found a significant degree of
malnutrition. Half of the study population developed some form of post-operative complication and nearly one quarter died. Of the ten nutritional markers studied, only serum
transferrin had predictive value in determining post-operative outcome. The mean level of serum
transferrin for patients with major complications was 162.0 mg/dl as compared with 221.2 mg/dl for those with none or minor complications. Patients with a serum
transferrin level below the reference range of 200 mg/dl had most of the major life threatening complications and deaths. The other nutritional markers studied did not correlate well with post-operative outcome. We feel that serum
transferrin is a useful nutritional marker to predict post-operative outcome and also to monitor the effect of
nutritional support. However, based on a preliminary study,
nutritional support may be required for periods longer than two weeks to show significant improvement in
protein-calorie malnutrition. We will consider giving adequate support for a longer period on a further study using serum
transferrin as a marker to determine its value in monitoring any reversal of
malnutrition.
