概括
在子宫内膜癌中,孤立的瘤细胞 (ITC) 可能代表早期的结节参与,与较大的转移不同. 这些患者表现出较少的攻击性,这表明精细的风险分层是可能的.
科学领域:
- 妇科瘤学 妇科瘤学
- 癌症病理学 癌症病理学
- 分子瘤学分子瘤学
背景情况:
- 子宫内膜癌 (EC) 管理依赖于结节分期和分子分类.
- 在EC结节分期中,孤立瘤细胞 (ITC) 的临床意义尚不清楚.
- 了解ITC生物学对于准确的风险分层和治疗计划至关重要.
研究的目的:
- 描述子宫内膜癌中孤立瘤细胞 (ITC) 的病理和分子特征.
- 为了比较ITC与负节点状态 (N0) 和已确定的节点转移 (N+).
- 评估ITC在EC进展中的生物学意义.
主要方法:
- 多中心,对1821名EC患者 (2018年6月 - 2024年5月) 的回顾性分析.
- 通过哨兵淋巴结 (SLN) 活检和分子分析进行手术分期.
- 将ITC病例 (通过超级定位或OSNA检测) 与N0和N+组进行比较.
主要成果:
- 在5.1%的患者中发现了ITC.
- 与N0.0相比,ITC病例的深层肌肉侵入率 (67.7%) 和淋巴血管空间入侵率 (LVSI) (52.1%) 显着更高.
- 在ITC中,MMR缺乏症更常见 (33.3%) 与N0 (25.0%),而p53异常在ITC中较少 (7.3%) 与N+ (19.4%).
结论:
- 在EC中的ITC可能代表了早期的,生物学上独特的节点参与形式.
- 与MMR缺乏和缺乏p53异常的关联表明ITC的潜在攻击性可能较小.

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...

The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance
5.1K
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...
