Outline of Final Research Achievements

The aims of this study were to reveal the nutritional status of patients after head and neck tumor treatment by using the Mini Nutritional Assessment-Short Form (MNA-SF) and to analyze the factors affecting nutritional status in patients with head and neck tumor. Forty-six participants (average age 74.7 years) were selected from patients who visited the maxillofacial prosthetics clinic of Tokyo Medical and Dental University Hospital Faculty of Dentistry in Japan. Nutritional status was evaluated using the MNA-SF. Multiple regression analysis was used to identify predictors affecting MNA-SF score. The candidate explanatory variables were age, sex, maxillofacial prosthesis use, number of residual teeth, resection side, neck dissection, and treatment option. The results showed that approximately half of the patients were at risk of malnutrition, and a regression equation for MNA-SF score was developed using two predictors: maxillofacial prosthesis use and neck dissection.
