Inclusion and exclusion criteria were applied, which resulted in 50 articles being included in this review. A search strategy was defined and a literature search was carried out in Medline. This review aimed to establish the evidence for using prostate FMs in terms of feasibility, implantation procedures, types of FMs used, FM migration, imaging modalities used and the clinical impact of FMs. A variety of FMs are available and they can be used in a number of ways. They require surgical implantation and provide a surrogate for the position of the prostate gland. Fiducial markers (FMs) for prostate IGRT have been in use since the 1990s. Prostate radiotherapy positioned using skin marks or bony anatomy may be adequate for delivering a relatively homogeneous whole-pelvic radiotherapy dose, but these surrogates are not reliable when using reduced margins, dose escalation or hypofractionated stereotactic radiotherapy.

Image-guided radiotherapy (IGRT) is an essential tool in the accurate delivery of modern radiotherapy techniques.
