概括
通过最不差异化的成分来评估瘤等级,而不是占主导地位,对于预测早期结直肠癌 (T1 CRC) 淋巴结转移风险至关重要. 这种方法提高了识别高风险患者的准确性,以获得更好的治疗策略.
科学领域:
- 在瘤学瘤学.
- 手术病理学手术病理学
- 癌症研究 癌症研究
背景情况:
- 日本的指导方针将高度瘤确定为T1结直肠癌 (CRC) 淋巴结转移 (LNM) 的风险因素.
- 当前的实践在确定瘤等级时有所不同,当T1CRC中存在多个分化水平时.
- 准确的风险分层对于T1 CRC的适当治疗至关重要.
研究的目的:
- 确定评估瘤分化的最佳方法,以预测T1CRC中的LNM风险.
- 为了比较LNM在T1 CRC中的"最小差异化"与"主要差异化"等级的预测值.
主要方法:
- 对971名经过手术切除的T1CRC患者进行了回顾性分析.
- 瘤分类评估使用最小和主要的差异化分析.
- 相关性和多变量逻辑回归分析来评估与LNM的关联.
主要成果:
- 淋巴结转移 (LNM) 在9.8%的患者中观察到.
- 最小差异化分析确定了17.0%的瘤是高等级的,与LNM显著相关 (p <0.05).
- 主导差异化分析发现只有0.8%为高等级,与LNM没有显著的关联 (p = 0.18).
- 最小差异化是LNM的一个独立预测因素 (OR 1.68,p=0.04).
结论:
- 基于最不差异化成分的瘤分类是T1CRC中LNM风险的更可靠的预测指标.
- 这种方法增强了T1CRC患者的风险分层.
- 使用最小分化分级可以指导更精确的治疗决策.

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...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
