概括
长期肝移植 (LT) 幸存者面临更高的死亡风险,特别是癌症和心血管疾病. 改善癌症查和心血管预防等策略可以提高移植后的生存率.
科学领域:
- 肝病学和移植外科手术
- 临床结果研究研究
背景情况:
- 肝移植 (LT) 后的长期结果 (>5年) 尚未得到充分证实.
- 了解5年后的生存率对于优化患者护理和资源配置至关重要.
研究的目的:
- 评估肝移植接受者在移植后至少存活五年的长期结果.
- 为了确定这种特定患者队列中死亡率的预测因素.
主要方法:
- 从三个大批量LT中心 (美国,英国,西班牙) 收集的前性数据的多中心追溯分析.
- 纳入标准:从计划开始到2010年12月31日接受LT的成年患者,在LT后至少有5年的生存期.
- 主要结局:患者存活;分析死亡原因和预测因素.
主要成果:
- 分析了3682名长期幸存者 (LT后≥5年),平均随访时间为10年.
- 49.4%的长期幸存者在随访期间死亡; 80.2%的这些死亡是过早的.
- 与一般人口相比,年龄标准化的死亡率在男性中高出3倍,在女性中高出5倍. 预测因素包括接受者/捐赠者的年龄较大,恶性瘤,心血管疾病和透析.
结论:
- 肝移植接受者存活超过5年的死亡率明显高于普通人群,主要是由于恶性瘤和心血管疾病.
- 实施诸如非侵入性癌症查,降低免疫抑制和密集心血管预防等策略可能会改善长期生存率.
- 需要进一步的研究来完善长期肝移植幸存者的管理协议.

Kidney Transplant I: Introduction
29
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Tissue Transplantation
396
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
