概括
区分良好的结肠神经内分泌瘤 (NETs) 是罕见的,仅占胃肠道胰腺NETs的0.5%. 状NET经常转移并导致癌症综合征,与通常是早期阶段的西格状NET不同.
科学领域:
- 胃肠病学 胃肠病学
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 结肠神经内分泌瘤 (NETs) 通常被认为是常见的和攻击性的.
- 现有的流行病学数据可能不准确地将差异化良好的NET与差异化不良的神经内分泌癌 (NEC) 组合在一起.
- 这种混杂妨碍了对分化良好的结肠NET的流行,行为和预后的准确理解.
研究的目的:
- 确定与其他主要部位相比,分化良好的结肠NET的流行率.
- 分析这些罕见瘤的临床行为,等级,阶段和预后.
- 为了区分 cecal NET 与 sigmoid NET 的特征.
主要方法:
- 对大型机构数据库的分析.
- 确定患有明显分化的结肠NET (不包括直肠NET) 的患者.
- 与其他胃肠道胰腺 (GEP) NET 的流行率,级别,阶段和预后进行比较.
主要成果:
- 分化良好的结肠NET仅占GEP NET的0.5% (19/3639年).
- 没有瘤起源于上升,横向或下降的结肠;主要瘤是头肠 (11) 或半头肠 (8).
- 状NET经常转移 (8/11) 并呈现癌症综合征 (6/11),不同于通常是早期的息肉的西格状NET.
结论:
- 区分良好的结肠NET异常罕见,分为两个不同的临床类别.
- 状网的行为类似于状网,而西格状网类似于直肠网.
- 流行病学数据可能会错误地描述结肠NET,包括NEC,从而掩盖了真正的临床情况.

Metastasis
5.4K
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...

Cancer Stem Cells and Tumor Maintenance
4.3K
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...
