背景情况:
- 在口腔状细胞癌 (OSCC) 中,逆侧淋巴结转移 (CLNM) 对结节阴性部患者构成重大临床挑战.
- 准确的风险分层对于指导选择性逆侧部剖析的决定至关重要.
- 现有的模型往往在预测CLNM在不同患者个人资料中缺乏准确性.
研究的目的:
- 在OSCC中开发一个可靠的模型来估计CLNM概率.
- 将关键的临床病理风险因素纳入贝叶斯框架.
- 为个性化外科管理提供数据驱动的见解.
主要方法:
- 对26项研究的系统性文献综述 (PubMed,Embase,2000-2024). 这是一项研究.
- 贝叶斯逻辑回归结合了七个风险因素:中线交叉,外节延伸 (ENE),两侧节点,入侵深度 (DOI),周围神经/淋巴血管入侵 (PNI-LVI),差异化和子站点.
- 贝叶斯蒙特卡洛模拟 (MCS) 使用无回转采样器 (NUTS) 与10万名虚拟患者.
主要成果:
- 没有风险因素的横向瘤的基线CLNM风险为4.2%.
- 单一的风险因素显著增加了CLNM的概率 (例如,中线交叉: 31.7%,ENE: 27.4%).
- 风险因素的组合会非线性地放大风险,在所有七个因素中达到93.7%. 确定了风险级别 (从最小到非常高).

Cancer Survival Analysis
634
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
392
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Combination Therapies and Personalized Medicine
5.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
