尹烨详解癌症新疗法：为什么日本癌症医疗技术更厉害？|《封面》对话

Core Viewpoint - Japan is the only country currently possessing the BNCT (Boron Neutron Capture Therapy) technology for cancer treatment, which has shown promising results in clinical applications, particularly for head and neck tumors [1][2]. Group 1: Technology Development - The BNCT technology was first discovered in the 1930s by French researchers, with unsuccessful attempts made by Americans in the 1950s, but Japan continued its research and development [2]. - Japan began preclinical studies in 2000, started clinical trials in 2016, and received approval for the technology in March 2020, quickly integrating it into their healthcare system by June 2020 [1][2]. Group 2: Clinical Applications and Efficacy - The initial approved indications for BNCT include head and neck tumors, with ongoing research to expand its use to breast cancer, pancreatic cancer, and other types [1][4]. - Among over 800 cases treated in Japan, the three-year survival rate for certain tumors has reached 60-70%, indicating significant potential despite current limitations in applicable indications [1][4]. Group 3: Equipment and Accessibility - Currently, there are only two clinical BNCT devices in Japan, one in Fukushima and one in Osaka, with the Osaka center not yet accepting international patients due to high domestic demand [3]. - The technology's expansion and accessibility in other countries, including China, is being considered, as there is a growing interest in the treatment [3].
