Abstract

Purpose

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.

Materials and methods

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.

Results

All 10 patients could walk without any support. No problem in the application was observed.

Conclusion

Our new ambulatory implant technique for HDR-ISBT was able to improve the performance status of prostate cancer patients.
