| Abstract: Malignant tumors represent one of the most severe global threats to human health, and their clinical treatment continues to pose significant challenges. To break through key technological barriers and promote the development of domestic high-end medical equipment, the Institute of Modern Physics, Chinese Academy of Sciences, has successfully developed China’s first heavy-ion therapy system with independent intellectual property rights, which has been officially implemented at Wuwei Tumor Hospital in Gansu Province. The deployment of this system offers a new precision treatment option for cancer patients both in China and internationally. This paper begins by outlining the development process of the heavy-ion therapy center at Wuwei Tumor Hospital, its overall profile, and disciplinary strengths. It systematically analyzes the dual advantages of heavy-ion therapy in terms of physical dose distribution and biological effects. The study highlights the treatment outcomes achieved with this system over the past five years and its notable efficacy in specific types of tumors. Research indicates that carbon ion therapy offers ten significant advantages over conventional radiotherapy. In comparison with international systems, China’s heavy-ion therapy system demonstrates unique technical features—the "Diamond Carbon Ion" approach—and achieves superior overall survival rates compared to foreign counterparts. Finally, the paper also introduces several innovative technologies developed by the hospital in clinical applications of heavy-ion therapy, providing valuable practical experience for the broader adoption of this technology and offering new hope and improved quality of life for cancer patients. |
