Implant geometry and detection rates of prostate fiducial markers after transrectal ultrasound-guided perineal implantation for image-guided 6D-tracking in robotic stereotactic body radiotherapy.

ABSTRACT:

Purpose

Fiducial markers (FM) are essential in prostate robotic stereotactic body radiotherapy (SBRT). Accuray® (Madison, WI, USA) provides an implantation guideline for reliable detection. We report on complication rates and analyze how the geometrical implantation quality correlated with subsequent detection rates. We also investigated whether factors such as single vs. double FM, body mass index (BMI), prostatic gland volume, and implantation-to-treatment interval were predictive for geometry and detection quality.

Methods

A retrospective analysis of 64 patients receiving transrectal ultrasound (TRUS)-guided transperineal implantation of ≥ 3 prostate FM and robotic SBRT between January 2011 and May 2021 was performed. Adverse events (AE) were classified according to the S
