行进中国｜精准定位让癌细胞无处遁形

Core Viewpoint - The article highlights the advancements in nuclear medicine, particularly the use of targeted radioligand therapy, which combines targeted molecules with therapeutic radioactive isotopes to effectively treat malignant tumors while minimizing damage to surrounding healthy tissues [1][4][5]. Group 1: Technology and Treatment - Radioligand therapy is described as a "tumor-targeting missile" that directly attacks cancer cells with minimal harm to healthy tissues [4]. - Lutetium-177 (Lu-177) is a key component of this therapy, capable of emitting beta particles that effectively destroy cancer cells by cutting their DNA chains [4]. - The therapy's precision is enhanced by the use of targeting ligands that guide the radioactive isotopes to the tumor sites, allowing for accurate diagnosis and treatment through PET/CT scanning [4][5]. Group 2: Clinical Applications and Achievements - The medical center has successfully treated various cancers, including lung, breast, and prostate cancers, utilizing integrated nuclear medicine techniques [5]. - In 2021, the center became the first in the country to apply actinium-225 for treatment, attracting patients nationwide [5]. - A recent collaboration with Sichuan Kelun-Botai Biopharmaceutical Co., Ltd. has led to the approval of the TBM-001 project for clinical research, marking a step towards independent development and domestic production of radiopharmaceuticals [5]. Group 3: Future Developments and Industry Growth - The city of Luzhou is positioning nuclear medicine as a key area for development, focusing on the innovation and industrial application of radioactive drug technology [7]. - The construction of the Southwest Medical University Affiliated Hospital Nuclear Medicine Center is underway, expected to be completed by 2026, which will include various specialized units [7]. - The center aims to advance its research in nuclear medicine and strive towards becoming an internationally leading institution in the field [7].
