For the radical treatment of tongue cancer, interstitial brachytherapy (ISBT) is often applied, because it is excellent in a concentration of the radiation dose.
In our institute patients with tongue cancer have been treated by the high dose rate (HDR) ISBT with a remote afterloading system (RALS), and the local control rates are 92% in T1 (< 2 cm) cases and 84% in T2 (< 4 cm) cases. And, we can prevent the osteoradionecrosis in the mandible as a late complication by using a newly invented protection device.
In this lecture, the adequate imaging modality for tongue cancer and the technique and the treatment result of the RALS-HDR-ISBT and the radiation protection device of tongue cancer will be presented.
