在非小细胞肺癌 (NSCLC) 患者中发现了Rothia细菌. 虽然Rothia存在与更糟糕的生存相关,但它也表明瘤扩散较少和更有利的免疫微环境.
科学领域:
- 在瘤学瘤学.
- 微生物组研究 微生物组研究
- 癌症基因组学 癌症基因组学
背景情况:
- 微生物组显著影响癌症生物学.
- 关于微生物对非小细胞肺癌 (NSCLC) 患者结局的影响的研究有限.
- 假设:特定的微生物与NSCLC患者的存活率相关.
研究的目的:
- 研究特定微生物与NSCLC患者存活率之间的关系.
- 确定与NSCLC不同存活率相关的微生物特征.
主要方法:
- 来自癌症基因组图谱 (TCGA) 的647名NSCLC患者的分析.
- 使用R软件进行数据分析.
- 使用火山图谱分析来比较短期和长期幸存者之间的微生物丰富度.
主要成果:
- 在短期幸存者中,Rothia是丰富的;在长期幸存者中发现了Blastococcus,Leptospira和Haematobacter.
- 仅仅罗西亚的存在与整体存活率有关.
- 罗阳性NSCLC显示细胞增殖减少,分数变化较少,同源重组缺乏,细胞透增加.
- 罗西亚阳性瘤表现出CD8 T细胞,CD4 T细胞,单细胞和NK细胞的透率较高,以及强大的干扰素马反应和T细胞受体丰富.
结论:
- 带有Rothia的NSCLC与较差的存活率有关,但也具有有利的瘤特征.
- 罗西亚的存在与细胞增殖的减少和瘤免疫微环境的改善有关.
- 罗西亚与NSCLC死亡率的关联可能独立于其瘤特征.

Cancer Therapies
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...
