This survey was performed to ascertain how usefully the remote afterloading machine with small radiative sources has been applied. The following results were obtained through questionaires sent to 147 hospitals in Japan: These machines are mainly used for the treatment of uterine cervix cancer, and the three channels of 60Co sources are mostly used with high dose-rate. The frequency of the treatment is 50-200 times per year in 60% of the hospitals. In only 15 hospitals is this machine routinely used for malignant tumors of the nasopharynx, paranasal sinuses, esophagus and bile tract as well as uterine cervix cancer. It is important to develop various kinds of accessories for the remote afterloading machine with high dose rate, in order to its extend the applications.
本次调查旨在确定带有小型放射源的遥控后装治疗机的应用效果。通过向日本147家医院发放调查问卷，得出以下结果：这些机器主要用于子宫颈癌的治疗，60Co源的三通道大多用于高剂量率治疗。60%的医院每年治疗次数为50 - 200次。只有15家医院将该机器常规用于鼻咽癌、鼻窦癌、食管癌、胆管癌以及子宫颈癌的治疗。为了扩大其应用范围，开发各种高剂量率遥控后装治疗机的附件很重要。
