概括
放射性成像低估了等待肝移植 (LT) 的三分之一患者的肝癌 (HCC) 负担. 这种不一致性增加了LT HCC后的复发和死亡率,需要改进监测和治疗策略.
科学领域:
- 肝胆道手术是肝胆道的手术.
- 移植手术 移植手术 移植手术
- 医学成像医学成像
背景情况:
- 增强对比度的横截面成像对于诊断,分期和管理肝细胞癌 (HCC),指导肝移植 (LT) 资格至关重要.
- 放射性 - 组织病理学不一致性可能导致不准确的分期,并对LT后患者的结果产生负面影响.
研究的目的:
- 为了评估经过LT的HCC患者的放射性-病原性异常.
- 评估这种不一致对LT后结果的影响,包括HCC复发和死亡率.
- 分析六个月等待政策对不一致率的影响.
主要方法:
- 对从已故捐赠者获得LT的成年HCC患者的联合国器官共享器官采购和移植网络 (UNOS-OPTN) 数据库的分析 (2012年4月至2017年12月).
- 比较LT前成像与解释性遗传病理学,以确定不一致.
- 卡普兰-梅尔和考克斯回归分析,以评估异常对3年HCC复发和死亡率的影响.
主要成果:
- 66.7%的患者在成像和探测两方面都符合米兰标准; 33.3%的患者在成像方面达到标准,但在探测方面超过了标准.
- 与增加不和相关的因素包括男性性别,较高的瘤负担,双边分布,较大的瘤大小和升高的AFP.
- 不一致性 (米兰以外的组织病理) 显著增加了LT后的死亡率 (adj HR 1.86) 和复发 (adj HR 1.32).
- 六个月的等待政策增加了不一致性 (OR 1.19),但没有影响LT后的结果.
结论:
- 目前仅基于成像的HCC分期低估了三分之一患者的瘤负担.
- 放射性 - 组织病理学不一致性与较高的LT后HCC复发率和死亡率有关.
- 加强监测和积极的局部区域治疗 (LRT) 对于被选中的患者来说是必要的,以改善结果.
