概括

微卫星不稳定性 (MSI) 增加了第三阶段结肠癌的积极外科边缘,影响了预后. 这表明需要采取质量改善举措和评估新辅助疗法,以减轻MSI阳性瘤患者的风险.

科学领域:

在瘤学瘤学.
手术病理学手术病理学
癌症基因组学癌症基因组学

背景情况:

欧洲研究将微卫星不稳定性 (MSI) 与第三阶段结直肠癌的积极外科边缘增加联系起来.
这种关联表明瘤生物学,而不是手术技术,可能是负面边缘的原因.
基于美国的国家注册表被用来验证这些欧洲发现.

研究的目的:

在美国队列中验证欧洲关于MSI和积极外科手术边缘之间的关联的观察.
调查MSI的预后影响和I-III阶段结肠癌的积极外科边缘.

主要方法:

从国家癌症数据库 (2010-2020年) 分析了患有病态阶段I-III结肠腺癌的成年患者.
统计分析以确定MSI状态,阳性边际和患者预后之间的关联.

主要成果:

MSI独立地与第三阶段结肠癌的积极边际相关 (OR 1.10).
阳性边际与第二阶段 (HR 1.26) 和第三阶段 (HR 1.40) 结肠癌的更差预后相关.
在III期癌症中,MSI的死亡风险较低 (HR 0.87),但在I或II期癌症中没有.

结论:

这项美国研究证实MSI与第三阶段结肠癌中阳性边际的更高概率有关.
研究结果表明,需要采取质量改善举措,并对新辅助疗法进行评估.
这项研究强调了在治疗结肠癌时考虑瘤生物学的重要性.

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...
