概括
循环瘤细胞 (CTC) 和它们的增殖率 (PCP) 可以预测肝细胞癌 (HCC) 复发. 这些标记物,以及CTC集群,提供了比传统生物标记物如α-fetoprotein (AFP) 更好的预后见解.
科学领域:
- 在瘤学瘤学.
- 分子诊断学 分子诊断
- 液体活检液体活检
背景情况:
- 循环瘤细胞 (CTC) 是肝细胞癌 (HCC) 诊断和预后的重要液体活检标志物.
- 分析CTC提供了对瘤特征和患者结果的见解.
研究的目的:
- 评估CTC数,CTC增殖百分比 (PCP) 和CTC集群在预测HCC复发中的预后价值.
- 为了比较CTC标记物与α-fetoprotein (AFP) 的预测性能.
主要方法:
- 从270名手术前HCK患者的外周血液系统分析.
- 对CTC数量,PCP (Ki67指数) 和CTC集群的量化.
- 与瘤特征和患者复发数据的相关性分析.
- 开发用于HCC复发预测的诺米克图模型.
主要成果:
- CTC数量和PCP与瘤大小,微血管入侵,多焦点性和血栓形成有显著的相关性.
- CTC数量和PCP显示出HCC复发的强大预测性能,表现优于AFP水平.
- 鉴定出CTC数量,PCP,CTC集群和微血管入侵是HCC复发的独立风险因素.

Cancer Stem Cells and Tumor Maintenance
5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Metastasis
5.6K
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...
