Gold fiducial marker tracking to optimize radiotherapy for organ-preserving treatment of muscle-invasive bladder cancer

Conclusions This is the first case series of intra-fraction GSM tracking for organ-preserving treatment of muscle-invasive bladder cancer. The data suggest that GSM tracking during radiotherapy for bladder cancer is feasible and associated with minimal intra- and inter-fraction displacement. With prospective investigation, this technique may be used to minimize target volumes and reduce radiation-associated toxicity.
