Gan No Rinsho. 1989 Feb;35(3):355-9.
Three cases of a bile duct carcinoma were treatment with radiotherapy, using intracatheterized 198Au grains. The intracatheter 198Au grains, placed in an inner tube, were inserted into a percutaneous transhepatic catheter. The number of 198Au grains used depended upon the length of the tumor. Tips of plastic were placed between the grains to improve the spatial and temporal dose allocation. The number of grains used can be changed quite easily, according to the length of the tumor, and the period of insertion in our cases was shorter than for a 192Ir wire. These three patients also received external irradiation and, since completion of treatment, two have continued to do well for the past 5 months. There have been no systemic or local complication.
三例胆管癌患者接受了放疗，采用经皮肝穿刺导管内植入198金颗粒的方法。将置于内管中的198金颗粒经皮肝穿刺导管插入。所用198金颗粒的数量取决于肿瘤的长度。在颗粒之间放置塑料尖端以改善空间和时间剂量分布。根据肿瘤长度，所用颗粒数量可轻松改变，且在我们的病例中，植入时间比192铱丝短。这三名患者还接受了外照射，自治疗结束以来，其中两名患者在过去5个月里情况良好。未出现全身或局部并发症。
