Drs. Lillian Siu and Melvin Chua discuss scientific innovations, disruptive technologies, and novel ways to practice oncology that were featured at the 2023 ASCO Breakthrough meeting in Yokohama, Japan, including CRISPR and gene editing, CAR T-cell and adoptive cell therapies, as well as emerging AI applications that are poised to revolutionize cancer care.   TRANSCRIPT Dr. Melvin Chua: Hello, I'm Dr. Melvin Chua, your guest host of the ASCO Daily News Podcast today. I'm a radiation oncologist and I currently practice in the Division of Radiation Oncology at the National Cancer Center in Singapore. I also served as the chair-elect of the ASCO Breakthrough Program Committee, and, on today's episode, we'll be discussing key takeaways from this year's Breakthrough meeting. The global meeting in Yokohama, Japan, brought together world-renowned experts, clinicians, med-tech, pioneers, and novel drug developers to discuss scientific innovations and disruptive technologies that are transforming cancer care today. I'm joined by Dr. Lillian Siu, the chair of the Breakthrough Program Committee. Dr. Siu is a senior medical oncologist at the Princess Margaret Cancer Centre and a professor of medicine at the University of Toronto.     You’ll find our full disclosures in the transcript of this episode, and disclosures of all guests on the podcast are available at asco.org/DNpod.    Lillian, it's great to be speaking with you today.    Dr. Lillian Siu: Thanks, Dr. Chua. I'm happy to be here.    Dr. Melvin Chua: We were just at ASCO Breakthrough, and it showcased some incredible scientific innovations, and really showed us how technology innovations in precision oncology, biotech, and artificial intelligence are transforming cancer care. What are your thoughts?    Dr. Lillian Siu: Yeah, it was a really exciting meeting, Melvin. The theme of this year's Breakthrough meeting was “Shining a Light on Advances in Cancer Care.” And our Opening Session featured an illuminating keynote address by the renowned thought leader and tech trailblazer, Dr. Hiroshi or “Mickey” Mikitani, the founder and CEO of Rakuten and Rakuten Medical. In his address that was titled, “Innovative Technology and Oncology,” he spoke so passionately about innovation and really seeing around the corner to predict what is coming and taking risks. And I think that's what medicine is about, not just what we have in front of us, but to predict and forecast what's coming. I totally was inspired by his address, and I think a lot of the audience felt the same way. He also spoke to us a bit about his company's development in photoimmunotherapy using novel technology and light therapy in head and neck cancer. And I think that's also an area of new technology that we should watch in the next few years.    Dr. Melvin Chua: I totally agree with you, Lillian. And one of the quotes that he spoke about really spoke to my heart. He spoke about the 2 choices: whether to do or not to do and not to do is not an option. So, I think that was a very compelling message to a lot of our audience at the meeting.    So, on this same note, innovation is a driving force in oncology, and we saw countless examples of this throughout the Breakthrough meeting. Were there any sessions that really stood out for you?    Dr. Lillian Siu: There were so many exciting sessions. First of all, there is the “Drugging the Undruggable” session. This is a really important session because in the past we felt that certain cancer targets such as KRAS, MYC, etc., are not druggable. KRAS G12C is the poster child in this area. So, during this session we heard about many ways that we are now looking to target these so-called undruggable molecules in the cancer cell. And we talked about molecular glues, we talked about degraders, and really novel ways that are not yet reaching the clinic, called “cyclic pe
