概括
将α-fetoprotein (AFP) 值降至10 ng/mL,可显著提高肝细胞癌 (HCC) 查在各种肝病 (包括MASLD和ALD) 的敏感性,同时保持高特异性.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 在瘤学瘤学.
- 生物标志物研究 生物标志物研究
背景情况:
- 血清α-fetoprotein (AFP) 对于肝细胞癌 (HCC) 查至关重要.
- 与酒精相关的肝病 (ALD) 和与代谢功能障碍相关的脂肪性肝病 (MASLD) 的增加率影响了AFP检测HCC的测试特征.
- 目前的AFP查门可能需要在不同肝硬化患者群体中重新评估.
研究的目的:
- 评估HCC诊断时AFP水平的趋势.
- 为了估计AFP在肝硬化患者中对HCC查的测试性能.
- 评估降低AFP值对不同肝病病因学查敏感性和特异性的影响.
主要方法:
- 使用退伍军人卫生管理局 (VHA) 数据 (2001-2021) 分析AFP趋势和诊断性能.
- 在不同的AFP值 (≥20 ng/mL和≥10 ng/mL) 上评估HCC查测试特征.
- 使用联合国器官共享网络 (UNOS) 数据验证发现.
主要成果:
- 在HCC诊断时的中位数AFP随着时间的推移而下降,并因肝病病因而异,在活跃HCV中最高.
- 将AFP值从≥20 ng/mL降低到≥10 ng/mL,可以显著提高整体HCC查敏感度 (31.7%至41.9%在VHA中).
- 这种降低值提高了所有病因 (活跃HCV,治愈HCV,ALD,MASLD) 的敏感性,特异性损失最小.
结论:
- 在患有MASLD,ALD和治愈的HCV肝硬化患者中,建议将AFP查值降至≥10ng/mL,以检测HCC.
- 这种调整显著提高了查灵敏度.
- 保持高特异性,确保在这些人群中可靠的HCC查.

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...
