概括
TP53和KRAS突变预测了手术后淋巴结阴性肝内胆管癌 (ICC) 患者的早期和更积极的复发. 这些遗传标记突出了需要向治疗以改善结果的高风险患者.
科学领域:
- 在瘤学瘤学.
- 遗传学 遗传学 是一个
- 手术病理学手术病理学
背景情况:
- 肝脏内胆管癌 (ICC) 的遗传变化具有预后价值.
- 个别突变对术后复发的具体影响,特别是在淋巴结阴性病例中,仍然不完全理解.
研究的目的:
- 综合评估特定基因突变对无复发存活率 (RFS) 和淋巴结阴性ICC.的复发后存活率 (PRS) 的影响.
- 确定与非常早期复发 (VER) 与长期无复发 (LNR) 相关的独特基因组资料.
主要方法:
- 分析了来自3个独立队列的589位局部ICC患者的临床病理和突变数据.
- 考克斯对RFS和PRS的比例危险模型,对预后突变的卡普兰-梅尔分析,以及对基因组分析的生存率分析的极端.
主要成果:
- 在查和验证队列中,TP53和KRAS突变与较短的RFS显著相关.
- 在非常早期复发 (VER) 病例中,TP53和KRAS突变更为频繁,并且在肝内和肝外复发 (IER) 患者中更为丰富.
- TP53突变与更糟糕的生存率和重复肝切除术后复发的可能性降低相关.
结论:
- TP53和KRAS突变是早期和更积极的复发的关键遗传预测因子,在节点阴性ICC患者的手术后.
- 这些发现强调了针对高风险瘤生物学的有效外科手术前治疗的必要性,以提高临床结果.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:24Liver Regeneration
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 large...
