Highlights • Baseline shifts in the direction of the heart are significantly related to overall survival.• There is an increased risk with increasing shifts towards the heart.• Shifts away from the heart reduce the risk, suggesting survival can be improved.• We recommend stricter heart dose constraints for lung SABR treatment planning.

图像引导后基线向心脏转移对肺 SABR 患者生存率的影响

亮点 • 基线向心脏方向的偏移与总生存率显着相关。• 随着向心脏偏移的增加，风险增加。• 远离心脏的偏移降低风险，表明可以提高生存率。• 我们建议更严格肺 SABR 治疗计划的心脏剂量限制。
