概括
淋巴结比率 (LNR) 和阳性淋巴结的日志几率 (LODDS) 改善了超越TNM分期的胃癌预后,即使有充分的淋巴结剖析. 这些指标为胃癌患者的整体生存期 (OS) 提供了增强的分层.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 病理学 病理学 病理学
背景情况:
- 瘤结节转移 (TNM) 分类是胃癌分期和生存预测的标准.
- 由于淋巴结 (LN) 剖析或病理检查不足,TNM分期的准确性可能受到限制.
- 像淋巴结比率 (LNR) 和阳性淋巴结的日志几率 (LODDS) 这样的替代分期系统可能提供更好的预后价值,特别是在低于最佳的淋巴结检查时.
研究的目的:
- 评估LNR和LODDS对经过激进胃切除术的胃癌患者的整体生存期 (OS) 的预后影响.
- 评估LNR和LODDS是否提供了与当前N分期系统相比更好的预后分层.
主要方法:
- 在2005年3月至2025年6月期间接受治疗性胃切除术的75名胃癌患者的回顾性分析.
- 评估潜在的预后因素,包括年龄,性别,瘤位置,T阶段,N阶段,TNM阶段,LNR和LODDS,使用单变量和多变量分析.
- 使用X-tile软件来确定LNR和LODDS生存分层的最佳切断点.
主要成果:
- 操作系统分析包括71名术后存活的患者.
- 该N分期系统没有准确地按OS对患者进行分层.
- 无论是LNR和LODDS,都有确定的切断点,显著地将患者分为三个不同的生存子组.
- 多变量分析证实LODDS和LNR是OS的独立预后因素.
结论:
- 与传统的N分期相比,LNR和LODDS提供了对淋巴结状况的更详细的见解,并提高了预后准确性.
- 这些系统改善了预后分层,即使在接受治疗性胃切除术的患者中,D2淋巴切除术和充分的淋巴结检索 (>15 LNs) 也可以改善预后分层.
- 由于样本规模较小和建议的切断值,建议在更大的研究中进一步验证.

Detailed Structure and Function of Lymph Nodes
4.6K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Gastric Motility
3.1K
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

Gastric Emptying
3.6K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Gastric Phase of Digestion
3.3K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...

Stages of Infection
65.2K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Second Order systems II
406
In an underdamped second-order system, where the damping ratio ζ is between 0 and 1, a unit-step input results in a transfer function that, when transformed using the inverse Laplace method, reveals the output response. The output exhibits a damped sinusoidal oscillation, and the difference between the input and output is termed the error signal. This error signal also demonstrates damped oscillatory behavior. Eventually, as the system reaches a steady state, the error diminishes to zero.
