At the invitation of the N.N. Petrov National Medical Research Center of Oncology, Professor Zhang Lian, Secretary-General of the International Society of Minimally Invasive and Noninvasive Medicine and President of Chongqing Haifu Hospital, attended the 11th White Nights International Oncology Forum in St. Petersburg, Russia, from July 2 to 5, 2025.

Prof. Zhang delivered a keynote presentation on "Clinical Application of Focused Ultrasound Ablation in Bone and Soft Tissue Tumors", highlighting breakthrough clinical achievements and long-term practice. His talk drew wide attention and sparked active discussion — especially from pediatric oncology experts in Russia.

With over 3,000 global participants and 500+ expert speakers, the White Nights Forum is one of the largest academic oncology events in Europe. This year's theme, "Integrating Medical Strength, Sharing Cutting-Edge Results," echoes the spirit of international collaboration.

Prof. Zhang's participation has laid a solid foundation for future Sino-Russian cooperation in noninvasive cancer treatment, and marked another milestone in the global influence of China's original HIFU technology.
