The aim of this study was to improve the performance status of prostate cancer patients during high-dose-rate interstitial brachytherapy (HDR-ISBT). To this end, we have developed a new ambulatory implant technique.
Ten prostate cancer patients were treated with HDR-ISBT as monotherapy from October 2003 until March 2004. We utilized a new removable template, a flexible applicator with a nonmetallic bead and button stopper, and an inner catheter connecting the applicator and the transfer tube of the brachytherapy unit. We shortened the connector end of the flexible applicator to enable the patient to sit down and walk freely during the treatment time.
All 10 patients could walk without any support. No problem in the application was observed.
Our new ambulatory implant technique for HDR-ISBT was able to improve the performance status of prostate cancer patients.
本研究旨在改善前列腺癌患者在高剂量率组织间近距离放疗（HDR-ISBT）期间的身体机能状态。为此，我们开发了一种新的门诊植入技术。
2003年10月至2004年3月，10例前列腺癌患者接受了HDR-ISBT单一疗法治疗。我们使用了一种新型可移除模板、带有非金属珠和纽扣塞的柔性施源器，以及连接施源器与近距离放疗设备传输管的内导管。我们缩短了柔性施源器的连接端，以使患者在治疗期间能够自由坐下和行走。
所有10例患者均可无需任何支撑行走。未观察到应用过程中的问题。
我们新的HDR-ISBT门诊植入技术能够改善前列腺癌患者的身体机能状态。
