概括
淋巴血管侵袭 (LVI) 和年轻年龄 (<60) 是T2直肠癌中淋巴结转移的关键风险因素. 识别这些因素有助于选择患者进行少入侵的局部切除,改善早期直肠癌的治疗策略.
科学领域:
- 结肠直肠手术 结肠直肠手术
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 由于淋巴结转移 (LNM) 风险,手术切除是T2直肠癌的标准.
- 局部切除可能适用于具有低LNM风险的选择患者.
- 确定T2直肠癌中LNM的风险因素对于治疗选择至关重要.
研究的目的:
- 确定T2直肠癌中淋巴结转移 (LNM) 的临床和组织病理风险因素.
- 评估包括年龄,性别,切除边缘,淋巴血管侵袭 (LVI),组织学等级,粘膜癌和围神经侵袭 (PNI) 在内的因素的重要性.
主要方法:
- 使用前性收集的数据进行基于登记册的回顾性人口研究.
- 对1607名T2直肠癌患者进行手术切除的分析 (2009-2021年).
- 单变量和多变量逻辑回归用于识别LNM的风险因素.
主要成果:
- 21%的患者 (343/1607) 有LNM.
- 淋巴血管侵袭 (LVI) (OR=4.21) 和年龄<60岁 (OR=1.80) 是LNM的重要独立风险因素.
- PNI,粘膜癌,组织学等级和非基因切除边缘不是显著的独立风险因素.
结论:
- 淋巴血管侵袭 (LVI) 是T2直肠癌中LNM的主要风险因素.
- 年龄较小 (<60岁) 是LNM的一个独立风险因素.
- 这些发现支持在早期的直肠癌管理中进行局部切除的风险分层.

Metastasis
5.5K
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
6.6K
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...
