ビッグデータでがん治療に革命が起こります

The video is a lecture by Dr. Bando from the National Cancer Center Hospital East, presented as part of a live event by the Japanese Cancer Therapy Society. The talk explains how big data and digital transformation (DX) can revolutionize cancer treatment. Dr. Bando begins by introducing the concept of a data-driven society and the importance of medical DX, highlighting Japan’s lag in digitalization compared to other countries. He discusses the potential of linking health data across a person’s lifetime (life-course data) to improve prevention and treatment. He cites Israel’s successful use of linked data during the COVID-19 pandemic, which enabled rapid publication of vaccine effectiveness. The lecture then focuses on the challenges of clinical trials, particularly the ethical issues of placebo-controlled trials when effective treatments are lacking. Dr. Bando proposes using historical placebo data from past trials to replace placebo arms in future trials, a concept he and colleagues have published. He also discusses the future of electronic health records, the use of AI to structure unstructured data, and the potential for decentralized trials. The talk concludes with a discussion on the societal implications of medical DX, including data ownership and the need for public acceptance. The Q&A session addresses questions about regional disparities, the use of real-world data for rare diseases, and the status of blood-based cancer screening tests.
