| Outline of Final Research Achievements |
Low dose-rate brachtytherapy is a definitive radiotherapy for early stage oral cancer. Au-198 grains are often used for the therapy; however, their supply has been insufficient since The Great East Japan Earthquake. The objective of this study was to examine whether Au-198 grains could be replaced by I-125 seeds usually used for the prostate cancer treatment. For this purpose, three dimensional absorption dose distribution was simulated and temporo-spatial kinetics of G2 arrest was analyzed. When applied to mold therapy using transient treatment instead of eternal implant, we tentatively propose that Au-198 grains could be replaced by I-125 seeds when ten times more number of I-125 seeds are used compared with that of Au-198 grains.
