| Outline of Final Research Achievements |
Treatment of breast cancer is carried out considering the occurrence of metastasis in lymph nodes. Extracting the lymph nodes for examining the metastasis causes side effects such as edema. For minimizing the invasiveness, sentinel lymph node biopsy is conducted. The sentinel lymph node refers to the first lymph node which receives lymphatic flow from the primary tumor. This lymph node is selectively extracted, and other nodes are preserved. In this study, we developed a magnetic probe system for identifying the sentinel lymph node by introducing magnetic fluid into the lymphatic system and by detecting the magnetic fluids accumulating in the sentinel lymph node. The system does not contain radioisotope, and the handheld detector is compact. Clinical trials were performed using the developed system. The results showed the advantages of this system over the existing techniques.
