Outline of Research at the Start

現在のがん治療はいまだ多くの領域で臓器特異的であり、腫瘍の性質ではなく発生部位で治療法が決まっている。このため、腫瘍の悪性度や遺伝子変異に基づいた個別化治療が期待されている。
そこで本研究では、Actionable変異数が口腔癌の病態や予後を規定する因子となり得るかを明らかにするために、Actionable変異数の異なる検体を用いて、実臨床での予後を確認する。さらに、Actionable変異というゲノムレベルの変化とCD44v, xCT, ALDHなど生物学的な治療抵抗性分子の発現を統合することにより、治療開始前に再発・転移や化学放射線療法の有効性を予測できる個別化治療法の確立を目指す。

Outline of Final Research Achievements

We examined the correlation between the number of actionable mutations, malignancy, and survival rate based on gene panel tests of oral cancer specimens that were operated on in our department. The presence or absence of actionable mutations tended to correlate with survival rates. However, there was no significant difference observed. We confirmed a correlation between actionable mutations and WPOI/tumor budding, which indicates malignancy. In addition, we observed a tendency that there is no correlation between the number of cancer gene mutations and age, alcohol consumption, or smoking. Our data suggests that the number of actionable mutations may serve as a basis for individualized treatments for oral cancer.

Academic Significance and Societal Importance of the Research Achievements

Actionable変異の数は口腔癌の悪性度との相関を認め、今後有益な予測因子となる可能性がある。全エクソン検査と異なり、簡便な癌遺伝子パネル検査で予後を推定できるため、臨床応用が容易であり、これらの方法を導入することにより、初期治療から個別化治療を目指すことができる可能性がある。
