Malignant tumor (cancer) is a common and frequently occurring disease. It seriously threatens human health and life, and has been a difficult problem all over the world. Surgery, radiotherapy and chemotherapy are the main means to treat cancer. The cure rate of various treatment methods in the world is 55%, of which 70% of patients have received radiotherapy to varying degrees. The mechanism of the interaction between conventional rays and substances determines that its impact on the surface of the body is stronger than that on the deep layer. Therefore, during treatment, conventional rays will cause obvious toxic and side effects on the normal tissues around the tumor, and even some serious complications.
During the interaction between ions and substances, the energy loss is concentrated in the range of millimeter at the end of the range. Radiotherapy using this characteristic of ions can adjust the ion energy to make the position of Bragg peak fall on the focus, so as to ensure the maximum killing of tumors and less damage to healthy tissues. Therefore, ion therapy is one of the ideal radiotherapy methods in the 21st century. The research of ion beam cancer treatment has become a frontier research hotspot in the field of radiotherapy. As an emerging technology industry encouraged by the state, ion therapy technology is being promoted by major domestic hospitals and local governments, forming a rare upsurge of ion beam therapy. In order to further and better promote the development of domestic ion therapy technology and the promotion of relevant equipment in China, let the masses understand relevant technologies and benefit patients.
In August 2020, the Institute of modern physics of the Chinese Academy of Sciences and the people's Government of Putian jointly founded Putian Lanhai Nuclear Medicine Research Center (hereinafter referred to as 'Lanhai research center') in Mazu health city, Meizhou Bay North Bank Economic Development Zone, Putian, the beautiful hometown of Mazu. The Lanhai Research Center will carry out technical research and equipment development related to nuclear medicine with the strong accumulation of ion therapy technology of the Institute of modern physics of the Chinese Academy of Sciences. Focusing on ion therapy and cutting-edge technology, with the support of the Institute of modern physics of the Chinese Academy of Sciences and the Putian Municipal People's government, the blue sea research center successfully held the first blue sea ion therapy cutting-edge forum academic seminar in the north bank economic development zone of Meizhou Bay, Putian from March 27 to 28, 2021. The second academic seminar of Lanhai ion therapy frontier forum was held in Putian from April 29 to May 1, 2022, focusing on expert reports and discussions to provide sufficient time for all parties to exchange and discuss. Shenzhen ruikang'an Technology Development Co., Ltd. actively participated in discussing the frontier development of particle therapy with guest teachers and sharing new technologies, methods and equipment of particle therapy.
On the morning of April 30, the second academic seminar of Lanhai ion therapy frontier Forum opened on the north bank. Su Yongge, director of the Standing Committee of Putian Municipal People's Congress and leader of the special leading group for the development and investment promotion of Putian life and health industry, Cai Guoping, deputy director and deputy leader, Lin Xiulan, Yu Xiaodong, Wang Guobin, Huang Fuquan and Cai Songqing, leaders of the north bank economic Development Zone, relevant medical experts, scholars and all members of Lanhai nuclear medical center attended. Xu Benhua, vice president of the Union Hospital Affiliated to Fujian Medical University, presided over the opening ceremony.
