Applicability of the general nutritional status score to patients with oral and maxillofacial malignancies.

The general nutritional status (GNS) score was used to assess the nutritional status of 127 consecutive patients with oral and maxillofacial malignancies. Forty-six of our patients (36.2%) were undernourished (group 2), while 81 (63.8%) were in good nutritional condition (group 1). Comparison of nutritional laboratory tests between these two groups showed that the differences in serum albumin, transferrin, and creatinine-height index (CHI) had statistical significance, yielding an excellent correlation between the GNS score and the nutritional laboratory test. Undernourished patients had a significantly higher postoperative complication incidence (48.3%) than well-nourished patients (19.4%) (chi 2 = 6.637; P < 0.01), indicating that the GNS score can be used as a prognostic index.
