概括
形态亚型和淋巴结比率 (LNR) 显著影响胰腺切除术后的存活率. 胰腺胆和胰腺亚型,以及高的LNR,表明预后较差.
科学领域:
- 在瘤学瘤学.
- 手术病理学手术病理学
- 胃肠病学 胃肠病学
背景情况:
- 在胰腺二切除术 (PD) 后,围癌的预后分层可以通过形态分类来改进.
- 周围瘤,尽管进行了手术切除,但呈现出不同的结果.
研究的目的:
- 调查PD后形态瘤亚分类 (肠道,胰腺,胰腺管腺癌) 和淋巴结比率 (LNR) 的预后价值.
- 为了确定在患者接受PD为周围恶性瘤的总生存 (OS) 的独立预测因素.
主要方法:
- 120个连续的PD (2005-2022) 的回顾性分析.
- 瘤分为肠道 (INT),胰腺胆 (PB) 或胰腺管腺癌 (PAN) 的亚型.
- 多变量考克斯回归和卡普兰-梅尔分析,包括临床病理学变量,包括LNR (截止值0.154).
主要成果:
- 与PB和PAN相比,INT瘤呈现较早的T阶段,较少的不良特征和较高的R0切除率.
- 在PB (HR 4.41) 和PAN (HR 13.96) 亚型中,与INT相比,观察到较高的死亡风险.
- 升高的LNR (≥0.154) 独立地预测了更糟糕的OS (HR 1.93).
- 平均使用寿命:INT (108.8个月),PB (62.0个月),PAN (22.7个月).
结论:
- 形态亚型和LNR是围癌PD后总生存期的独立预后因素.
- 将这些因素整合到风险模型中可能会增强术后患者分层,并指导辅助治疗决策.

Adrenergic Receptors: ɑ Subtype
2.6K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

Classification of Epithelial Tissues: Glandular Epithelium
11.6K
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.

Cadherins in Tissue Organization
3.8K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
