Outline of Final Research Achievements

Triple Negative Breast Cancer Is known to have very poor prognosis. We have conducted neoadjuvant platinum-based chemotherapy for over 40 patients and median follow-up period is now over 4 years. We have excellent prognosis for patients we treated, and we are analyzing immunological biomarker in conjunction with pharmacokinetics of platinum.

Academic Significance and Societal Importance of the Research Achievements

トリプルネガティブ乳癌は組織学的高悪性度で早期再発が多く予後不良で、明確な治療標的薬もなく治療に難渋する。更に術前化学療法で病理学的完全反応(pCR)に至らない場合は極めて予後不良である。京都大学にてCDDP含有術前化学療法を行った症例におけるEvent-free survivalは、pCR有無に関わらず同等であり、pCRによって大きな差が認められた非CDDP症例と対照的であった。non pCR症例においてもCDDPが何らかの再発抑制効果持続(NK活性)に寄与していいる可能性が示唆された。今後は免疫チェックポイント阻害剤などとの併用で更なる治療成績向上につなげていきたい。
