概括
混合性肝细胞癌与胆管癌 (HCC-CCA) 是侵略性的,并且很难在LT前检测到. 与HCC患者相比,HCC-CCA患者在肝移植 (LT) 后的生存率更差,复发率更高. 改进的诊断对于改善患者的治疗结果至关重要.
科学领域:
- 肝胆道手术 肝胆道手术
- 移植瘤学 移植瘤学
- 胃肠病学 胃肠病学
背景情况:
- 混合肝细胞癌与胆管癌 (HCC-CCA) 是一种罕见但具有攻击性的初级肝癌.
- 不侵入性地区分HCC-CCA和纯肝细胞癌 (HCC) 是一个挑战.
- 对于偶然诊断的HCC-CCA来说,了解肝移植 (LT) 后的结果至关重要.
研究的目的:
- 为了比较偶然诊断的HCC-CCA患者与LT后纯HCC患者的结果.
- 为了识别LT前和扩散性病理学特征的差异.
- 评估HCC-CCA对LT后的整体和无复发生存时间的影响.
主要方法:
- 从2008年6月9日到2023年6月9日,对1898名为HCC接受LT治疗的患者进行了回顾性审查 (n=493).
- 19名偶然诊断的HCC-CCA患者的HCC患者的倾向性得分匹配.
- 独立分析使用前LT (匹配1) 和扩散病理学 (匹配2) 特性.
主要成果:
- 在HCC-CCA患者中,在Milan或UCSF标准之外的患者更常见 (p=0.01).
- HCC-CCA患者接受了更多的新辅助微波切除 (p=0.02).
- 在两个匹配的队列中,HCC-CCA患者的整体和无复发生存率显著降低 (p<0.001).
结论:
- 在LT之后,HCC-CCA表现出与高复发率相关的侵略性表型.
- 目前的非侵入性方法不足以区分HCC-CCA和HCC.
- 开发新的查工具和生物标志物对于及时诊断和改善LT后管理至关重要.

Sign Test for Matched Pairs
428
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

Wilcoxon Signed-Ranks Test for Matched Pairs
507
The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Liver Histology
4.5K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

Liver Physiology
3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Liver Regeneration
4.4K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Gross Anatomy of the Liver
2.1K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...
