Outline of Research at the Start

唾液腺高悪性度転化癌は、通常型の低悪性度の唾液腺癌を発生母地として、その一部が高悪性度の未分化癌への転化をきたす予後不良の病態である。しかし、コンセンサスの得られた明確な診断基準は確立されておらず、標準的治療法も確立されていない。本研究では、蓄積した約50例の高悪性度転化癌の標本を用いて、病理組織学的、免疫組織化学的アプローチ、コピー数解析および網羅的遺伝子解析などの多面的な解析から、高悪性度転化癌の診断基準の確立、腫瘍発生機序の解明、免疫逃避分子機構の解明を目指す。本研究により得られた知見は、高悪性度転化癌の新たな治療戦略につながることが期待され、臨床的に意義深いものとなると考えられる。

Outline of Final Research Achievements

High-grade transformation of the salivary gland carcinoma (HGT) is a HG-carcinoma arising in low-grade salivary gland cancer. 50 cases of HGT were histologically re-evaluated, and immunohistochemical staining for driver gene variant and proliferation markers performed. DNA was separately extracted from LG and HG components, and mutation analysis, copy number analysis, and methylation analysis were performed. Immunohistochemical markers of immune microenvironment were stained. At this stage, it has been found that certain gene deletions are frequently observed in HGT. Additionally, similar copy number abnormalities are noted in the LG component of HGT, suggesting that there are genetic characteristics that lead to transformation at the LG stage.

Academic Significance and Societal Importance of the Research Achievements

これまで高悪性度転化癌の発生機序は解明されておらず、標準的治療法も確立されていなかった。本研究で、高悪性度転化を来す可能性を示唆する遺伝子異常の特徴が特定された。低悪性度の癌であっても、これらの特徴を調べることにより、高悪性度転化を来す可能性を知ることができ、治療の選択や切除後のフォローの方針の決定に寄与することができる。また、これらの遺伝子異常に対する治療法の開発が進むことによって、高悪性度転化に特徴的な治療戦略につながる可能性も考えられる。さらに、免疫チェックポイントマーカーの発現が高悪性度成分のみでみられる症例もあり、免疫チェックポイント阻害剤を用いた治療が期待される。
