Transrectal implantation and stability of gold markers in prostate bed for salvage radiotherapy of macroscopic recurrences

Highlights • Transrectal implantation of gold markers in the prostatic bed is possible. • Salvage focal dose irradiation of macroscopic relapse after prostatectomy is feasible. • Gold markers are stable in prostate bed for salvage focal irradiation. • The distance variation between two gold markers could be considered as non-relevant. • Development of new approaches of focal irradiation into the macroscopic relapse after prostatectomy.
