A Systematic Review and Meta-Analysis of Liver Tumor Position Variability during SBRT using Various Motion Management and IGRT Strategies
CONCLUSION: Our meta-analysis suggested that weighted-mean PTV margin of 6mm might be appropriate for BH. For AC and FB, asymmetric PTV margins (weighted-mean margin = 4mm (AP), 6mm (SI/LR)) might be appropriate. For FB, if larger (> ITV margin) intra-fraction variability observed, the additional intra- and inter-fraction variability should be accounted in the PTV margin.PMID:34843841 | DOI:10.1016/j.radonc.2021.11.022
