Outline of Final Research Achievements

In this study, we tried to reveal mechanism of onset of thymic epithelial tumors with special reference to possible viral involvement using comprehensive mRNA expression profiling of 770 immune-related genes.
Contrary to our expectation, no direct involvement of viral infection could be detected. However, we found that PRAME (Preferentially expressed antigen in melanoma) was specifically expressed in thymic squamous cell carcinoma, whereas thymomas displayed negative expression or focal and weak expression.
These results identified PRAME as a novel diagnostic marker differentiating thymic squamous cell carcinoma from thymoma.

Academic Significance and Societal Importance of the Research Achievements

胸腺上皮性腫瘍の発症にウィルスが関与していることの証明は当初の期待とは異なり、本研究では直接的な証明はできなかった。
しかしながらPRAMEが胸腺癌特異的マーカーであり、免疫組織化学染色で既知の鑑別マーカーであるCD5やCD117と組み合わせることで胸腺癌のより正確な診断に有用であることが証明された。
胸腺癌と胸腺腫の鑑別診断は時に困難であることが知られており、PRAMEの免疫染色により鑑別診断制度を高め、ひいては治療選択に貢献できる可能性が本研究から示唆された。今後症例を蓄積しPRAMEのマーカーとしての有効性を検証していく必要がある。
