概括
在食道状细胞癌 (ESCC) 中新辅助化疗 (NAC) 后的高线粒体状况预测了更差的生存率. 这种Mito-score可以作为预后生物标志物,特别是在晚期.
科学领域:
- 在瘤学瘤学.
- 癌症生物学 癌症生物学
- 翻译研究是翻译研究.
背景情况:
- 在食道状细胞癌 (ESCC) 中新辅助化疗 (NAC) 后线粒体状况的预后意义尚不清楚.
- 在ESCC中,线粒体状态和瘤微环境 (TME) 之间的关联需要进一步调查.
研究的目的:
- 评估ESCC中NAC后线粒体状态 (线粒体得分) 的预后值.
- 探索Mito-score和TME参数 (T细胞密度,PD-L1表达) 之间的关系.
主要方法:
- 对202名ESCC患者进行NAC和手术治疗的分析.
- 使用基于免疫组织化学的Mito-score量化线粒体状态.
- 高和低Mito-score组之间的临床病理特征,TME和生存结果的比较.
- 多变量考克斯回归用于预后因素识别.
主要成果:
- 在69.3%的患者中观察到高Mito-score.
- 在高Mito-score瘤中更高的编程死亡联体-1 (PD-L1) 表达;T细胞密度显示没有差异.
- 在所有阶段,高的Mito-score与明显更差的整体存活率 (OS) 相相关.
- 在晚期 (ypStages III-IV) 中,高的Mito-score预测了较差的癌症特异性存活率 (CSS).
结论:
- 在NAC之后的高Mito-score是ESCC中不利的OS和CSS的独立预测器.
- 线粒评分可以作为一个有价值的预后生物标志物,特别是在NAC后的晚期病理阶段的患者中.

01:46Electron Transport Chain: Complex I and II
18.4K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
