Abstract: PURPOSE: To evaluate the potential nutrition risk and analyze relative factors in patients with oral and maxillofacial cancer, and explore the treatment method of nutrition risk. METHODS: Eighty eight patients with oral and maxillofacial cancer were included in the present study. Their age, height, weight, clinical classification, level of hemoglobin、albumin and prealbumin,present treatment were recorded and patients' body weight index (BMI) was calculated and scored based on a table of nutrition risk evaluation. The data were analyzed using SPSS 17.0 software package. RESULTS: In 88 cases of patients with oral and maxillofacial cancer, 18 patients had malnutrition (BMI<18.5 kg/m²), accounting for 20.45%; 49 patients had nutrition risk (NRS2000≥3 points), accounting for 55.68%. CONCLUSIONS: Patients with oral and maxillofacial cancer had high nutrition risk. The older the age, the higher the nutrition risk will be. Anemia, low albumin and low prealbumin will increase the incidence of nutrition risks.
