The 2026 CACA-SIS Anti-Cancer Summit, jointly hosted by China Anti-Cancer Association (CACA), Senologic International Society (SIS), and the World Association for Integrative Oncology (WAIO), concluded successfully on the evening of March 21, 2026. The summit attracted viewers from countries including China, the United States, France, Germany, the United Kingdom, the Netherlands, Italy, Turkey, Russia, and Palestine, with a total online viewership reaching 10.31 million.

The summit was co-chaired by Prof. Yinf Wang, Vice President of CACA, and Prof. Tolga Ozmen, Vice President for North America of SIS.Opening remarks were delivered by Prof. Daiming Fan, President of CACA, and Prof. Carole Mathelin, President of SIS. Keynote presentations were given by Prof. Elizabeth Berger from Yale Cancer Center in the United States and Prof. Keda Yu, Director of the Breast Surgery Department at Fudan University Shanghai Cancer Center.

Opening Addresses, Launching an Academic Feast

At the start of the conference, Prof. Fan, President of CACA, AOS, and WAIO, delivered the opening address. On behalf of the organizers, Prof. Fan extended a warm welcome to global participants. He emphasized that, with the deepening concept of integrative oncology, conducting cross-border and interdisciplinary in-depth discussions on specific issues in breast cancer diagnosis and treatment is of great significance for advancing global cancer prevention and control. Prof. Fan introduced the recent developments and achievements of CACA, noting that the association holds hundreds of academic exchange activities across China each year. In particular, the monthly International Anti-Cancer Summit has become an important bridge connecting oncology communities in China and abroad and sharing cutting-edge achievements. Prof. Fan extended a sincere invitation to global colleagues in the field of breast health to gather in Tianjin in May for the 23rd World Breast Health Congress, co-organized by CACA and SIS. Prof. Fan expressed his hope that the partnership between the two associations would continue to grow, contributing further to the cause of global breast health in collaboration with colleagues worldwide.

Subsequently, Prof. Carole Mathelin, President of SIS and Dean of the French National Academy of Surgery, delivered a speech. She highly praised the academic value of the summit and expressed her gratitude to CACA for organizing this event. She noted that sharing experiences and advancing technologies through academic exchange networks would benefit cancer patients globally. Prof. Mathelin introduced cutting-edge developments in European breast surgery concerning axillary lymph node management, including sentinel lymph node biopsy, treatment de-escalation, and surgical exemption strategies. She highlighted that, under the premise of precise patient selection, overtreatment can be avoided without compromising patient survival benefits, showcasing the mainstream concepts and latest research findings in Europe in this field.

Focusing on Frontiers, Experts from China and the U.S. Discuss on the Same Platform

During the keynote session, leading breast cancer experts from China and the United States shared their respective countries’ diagnostic and treatment strategies and future directions.

Prof. Elizabeth Berger from Yale Cancer Center presented a talk titled “To Dissect or Not to Dissect: Management of the Axilla in the United States.” She reviewed the evolution of axillary management in breast cancer in the United States, from traditional dissection to precise approaches. She concluded that reducing axillary surgery has become a mainstream trend, but caution is still needed in cases with high nodal burden or aggressive tumors.

Following this, Prof. Keda Yu, Director of the Breast Surgery Department at Fudan University Shanghai Cancer Center and recipient of the National Science Fund for Excellent Young Scholars and the National Science Fund for Distinguished Young Scholars, delivered a lecture entitled “Axillary Management of Breast Cancer in China: Guidelines, Practices, and Future Directions.” Prof. Yu, referencing the relevant guidelines of the CACA’s Breast Cancer Committee, illustrated the rapid development and distinctive features of breast cancer diagnosis and treatment in China. He showcased domestic innovations in areas such as artificial intelligence prediction models, nano-label precise localization, rapid pathological imaging, and integrated diagnosis and treatment.

Exchanging Views, Building Global Consensus

During the roundtable discussion, participating experts engaged in an in-depth exchange regarding clinical differences in axillary management. On the question of whether elderly patients should be exempted from axillary lymph node dissection, Prof. Berger noted that for patients aged 70 and above meeting specific low-risk criteria, omitting this procedure has been gradually implemented in the United States. Prof. Yu emphasized that Chinese patients tend to have a younger age of onset, necessitating more cautious clinical decisions supported by local data. Prof. Fan concluded that the differences in ethnicity, genetic backgrounds, and clinical practices highlight the importance of conducting international comparative studies. The experts agreed that strengthening multi-center collaboration and leveraging new technologies such as AI and genetic testing are crucial for advancing precision and individualized axillary management.

The successful hosting of this CACA-SIS Anti-Cancer Summit not only established a platform for dialogue between East and West, fully showcasing the latest advancements in breast cancer axillary management in China and the United States, but also marked the entry of the partnership between CACA and SIS into a new phase of deeper and broader cooperation. Moving forward, we will actively integrate into the global cancer governance system, continue to build an academic exchange platform with extensive international influence, and contribute more Chinese wisdom and strength to the cause of human health.
