Outline of Final Research Achievements

The screening test that use artificial brains to analyze metabolites such as polyamines and acetylated polyamines measured using LC-MS to predict cancer risk are already in practical use. In this study, an immunochromatographic assay targeting metabolites specifically elevated in cancer was established. The immunochromatography kit we have developed correlates well with LC-MS measurements, and we believe it is sufficiently robust for clinical use. If a cutoff value that balances sensitivity and specificity is established through repeated clinical trials, it is expected to be possible to use the kit as a zero-level screening test.

Academic Significance and Societal Importance of the Research Achievements

ポリアミンやアセチル化した代謝物質などを人工頭脳で解析し、癌のリスクを予測するスクリーニング検査はすでに実用化されている。特に重要と考えられる代謝物を標的としたイムノクロマトアッセイが確立できた。今回開発したイムノクロモトキットは、LC-MSの測定値と相関性を示した。臨床試験などを繰り返し、感度と特異度とのバランスを考えたカットオフ値を設定すれば、0次スクリーニング検査として活用することも可能になると期待される。
低価格で簡便な癌に対するマススクリーニング検査の提供は、疾患の早期診断と早期介入を可能にし、低侵襲治療により早期の社会復帰を目指す未来型医療にイノベーションを起こすと期待される。
