Outline of Final Research Achievements

In the present study, an attempt was made to clarify the hypothesis that chemotherapy changes gene expression of taste receptors in the tongue to induce dysgeusia in patients with head and neck cancer. The present study enrolled 21 patients who received chemoradiotherapy for head and neck cancer. The mRNA levels of taste receptor subunits: T1R1, T1R2, T1R3 and T2R5 were measured in the scrapings of lingual mucosa obtained with a small spatula. In 17 patients with mild/moderate stomatitis, mRNA levels of T1R3 were significantly and transiently decreased, while those of T2R5 mRNA significantly and transiently increased after chemotherapy. There was a negative significant correlation between the perception thresholds of umami or sweet tastes and lingual mRNA levels of T1R3 in patients with mild/moderate stomatitis after chemotherapy. Lingual mRNA levels of T2R5 were significantly increased in patients who complained of phantogeusia after chemotherapy.
