主 题:Endoscopic ultrasound Pancreatic cancer Fiducial marker Image-guided radiotherapy Systematic review Meta-analysis
摘 要:BACKGROUND Pancreatic cancer(PC)mortality remains high despite advances in *** chemoradiotherapy offers modest survival benefit over monotherapy with *** markers serve as needed landmarks for imageguided radiotherapy(IGRT).Traditionally,these markers were placed surgically or percutaneously with limitations of *** ultrasound-guided placement overcomes these *** To evaluate the safety,efficacy,and feasibility of endoscopic ultrasound(EUS)-guided fiducial placement for PC undergoing *** Articles were searched in MEDLINE,PubMed,and Ovid *** was conducted by fixed and random effects *** was assessed using Cochran’s Q test based upon inverse variance *** Initial search identified 1024 reference articles for EUS-guided fiducial placement in *** these,261 relevant articles were *** was extracted from 11 studies(n=820)meeting inclusion *** proportion of successful placement was 96.27%(95%CI:95.35-97.81)with fiducial migration rates low at 4.33%(95%CI:2.45-6.71).Adverse event rates remained low,with overall pooled proportion of 4.85%(95%CI:3.04-7.03).CONCLUSION EUS-guided placement of fiducial markers for IGRT of PC is safe,feasible,and *** ability to target deep structures under direct visualization while remaining minimally invasive are added ***,the ability to perform fine needle aspiration or celiac plexus neurolysis add value and increase patient-care *** EUS-guided fiducial placement improves outcomes in IGRT or offers any mortality benefits over traditional placement remains unknown and future studies are needed.
