EUS-guided fiducial placement for GI malignancies: a systematic review and meta-analysis

Image-guided radiotherapy (IGRT) allows the delivery of radiation with high precision to a target lesion while minimizing toxicity to surrounding tissues. Endoscopic ultrasound (EUS) provides excellent visualization of GI tumors and consequently is being used for fiducial placement with increased frequency. Our goal was to perform a systematic review and meta-analysis of studies evaluating the technical aspects, safety and efficacy of EUS fiducial placement for IGRT in GI malignancies.
