| Outline of Final Research Achievements |
In radiotherapy for cervical cancer, external beam radiaton therapy and intracavitary brachytherapy are applied in combination, but there were no established methods to evaluate the therapeutic effectiveness comprehensively. In this research, a comprehensive method to evaluate not only the 3-dimensional distributions of physical dose but also biological effectiveness dose (BED) was established. This analysis showed that the 3-dimensional evaluation of BED in the combination of central-shielding pelvis irradiation and intracavitary brachytherapy implemented in Japan was feasible and that this treatment method is effective in treating the primary disease while avoiding normal tissue complications. This research was introduced in the ICRP Report 89, which was published by the International Commission on Radiation Units & Measurements in 2016 to standardize the brachytherapy for cervical cancer globally, and contributed to establishment of comprehensive evaluation method in radiotherapy.
