Outline of Final Research Achievements

We conducted comprehensive metabolite analysis of serum samples obtained from 66 breast cancer patients who had neoadjuvant chemotherapy, using capillary electrophoresis time-of-flight-mass spectrometry (CE-TOF-MS). 16 luminal, 33 HER2, and 17 tiple negative breast cancer were included. Pathological complete response (pCR) was found in 30 cases. One metabolite, 3-Indoxylsulfate was tended to be lower concentrations in pCR patients compared with non-pCR patients.

乳がん患者におけるメタボローム解析

Academic Significance and Societal Importance of the Research Achievements

メタボローム解析によって得られた効果予測マーカーを臨床情報と合わせて解析することにより、定量的かつ客観的な指標で癌を特徴化することができれば、化学療法の個別化や、さらには予後予測などへの活用も期待できる。医療の標準化で陥りやすい過剰医療を防ぎ、個別医療化に向けたマーカーを同時に探す研究例は、学術的な成果だけでなく、医療経済的なインパクトが高い。
