On April 12, 2025, the “Best of St. Gallen 2025” session, co-hosted by the Breast Cancer Committee of the Chinese Society of Clinical Oncology (CSCO BC) and the St. Gallen International Breast Cancer Conference (SGBCC), was successfully held during the National Breast Cancer Conference in China.

Following the successful “Voice of China” session led by Chinese experts at last month’s SGBCC conference, this marks the first time that the SGBCC has held a dedicated academic session in China. The event signifies a new chapter in bilateral academic exchange, highlighting the growing synergy between Eastern and Western approaches to breast cancer diagnosis and treatment.

Opening Remarks from the Chair: A Shared Vision for Progress

In opening address, Professor Zefei JiangConference Chair, President-Elect of CSCO, and professor at the Chinese PLA General Hospital extended a warm welcome and heartfelt thanks to the experts from SGBCC and all participants attending the session.

Reflecting on the journey since 2011, when Chinese scholars first began participating in the St. Gallen International Breast Cancer Conference, Professor Jiang highlighted the growing depth of collaboration between China and SGBCC. What began as a process of learning and adaptation has evolved into one of mutual inspiration and innovation. China has not only absorbed the essence of SGBCC’s academic insights to enrich its national guidelines but has also increasingly contributed original ideas and evidence-based practices, bringing the wisdom of Chinese oncology to the global stage.

Following the presentations, participating experts engaged in an in-depth discussion on the latest updates and ongoing controversies within the St. Gallen International Consensus on Early Breast Cancer, with a particular focus on how these recommendations can be integrated into clinical practice in China. This dialogue not only deepened academic exchange between Chinese and international experts but also contributed to advancing breast cancer diagnosis and treatment strategies.

East Meets West, Advancing Together

The “Best of SGBCC” session has become a flagship platform for annual dialogue between Chinese and international breast cancer experts. It not only fosters meaningful integration between global clinical consensus and local Chinese practice, but also facilitates in-depth exchange on key topics such as the development of immunotherapy, precision medicine strategies, and standardized application of ADC therapies.

As the mutual exchange mechanism between CSCO BC and SGBCC continues to strengthen, this collaboration will further accelerate the global dissemination of China’s innovations in breast cancer treatment, while supporting the localized adoption of international guidelines. Together, these efforts aim to contribute powerful solutions from the field of breast oncology to the broader vision of a shared global community of health.
