Brachytherapy in the treatment of prostate cancer is an accepted modality. A considerable experience has been accrued using Iridium interstitial therapy. The major problem associated with this choice is that of radioprotection. We describe the first clinical use of the MicroSelectron, a remote afterloading device, in prostate brachytherapy. Twenty-six patients have now been treated using this system. Approximately 55 treatment interruptions with an average 5 hr increase in overall treatment time occurs. The initial problems associated with instituting remote afterloading to prostate brachytherapy and their solutions are discussed.
近距离放射治疗是治疗前列腺癌的一种公认的方式。使用铱间质治疗已经积累了相当多的经验。与这种选择相关的主要问题是放射防护问题。我们描述了微型后装设备MicroSelectron在前列腺近距离放射治疗中的首次临床应用。目前已有26例患者使用该系统进行了治疗。出现了大约55次治疗中断，总体治疗时间平均增加了5小时。文中讨论了在前列腺近距离放射治疗中采用遥控后装技术最初出现的问题及其解决方法。
