概括
循环瘤DNA (ctDNA) 在非小细胞肺癌 (NSCLC) 的预后价值有限. 早期的CEA水平变化是这些患者无进展生存的更有效预测指标.
科学领域:
- 在瘤学瘤学.
- 分子诊断学 分子诊断
- 胸部外科手术 胸部外科手术
背景情况:
- 循环瘤DNA (ctDNA) 是非小细胞肺癌 (NSCLC) 的预后生物标志物.
- 在NSCLC中ctDNA的预后作用与膜扩散 (M1a) 并不清楚.
- M1a NSCLC的特点是生物学的惰.
研究的目的:
- 评估ctDNA在患有M1a疾病的NSCLC患者的诊断和预后价值.
- 为了比较ctDNA和CEA监测对预测无进展生存 (PFS) 的有效性.
主要方法:
- 在41名M1a NSCLC患者中,对串行ctDNA和CEA水平进行了监测.
- 无进展生存期 (PFS) 根据ctDNA和CEA水平进行评估.
- 用于验证的是61名M1a患者的独立队列.
主要成果:
- 诊断时ctDNA检测率为22%,而CEA检测率为55%.
- 在患有进展的多叶性转移的患者中,ctDNA的敏感性较低 (50%).
- 在可检测和不可检测ctDNA的患者之间没有观察到PFS的显著差异.
- 在诊断后3个月内,CEA下降趋势与改善的PFS相关 (HR:0.22,p=0.004),在验证队列中得到证实.
结论:
- 带有M1a孤立膜扩散的NSCLC可能是一种"非流放"瘤类型.
- 在这种特定的NSCLC亚组中,ctDNA的诊断和预后效用有限.
- 监测早期的CEA变化为预测疾病进展提供了更具成本效益的方法.

lncRNA - Long Non-coding RNAs
8.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Metastasis
5.7K
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...
