概括
临床医生可以通过初始生长率来分层增长的前庭神经瘤,以预测未来的生长. 在初始生长检测之前,瘤的体积翻了一番,通常需要在5年内进行治疗.
科学领域:
- 神经外科 神经外科
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 静脉瘤 (VS) 是可以随着时间的推移生长的瘤.
- 持续观察 (等待和扫描) 是一些患有增长VS的患者的选择.
- 预测后续增长对于管理决策至关重要.
研究的目的:
- 为了确定初始生长行为是否可以分层的患者与成长的零星前庭神经瘤.
- 根据最初的体积增长率来评估后续增长的可能性.
主要方法:
- 对952名偶发性VS患者的3,505次连续MRI研究的分析.
- 卷度瘤测量以计算生长速度.
- 基于年度体积增长率的分层:<25%,25-50%,50-100%和≥100%.
主要成果:
- 最初的增长率显著预测了随后的增长或治疗需要.
- 年增长率≥100%的患者在随后的增长/治疗中具有2.01的危险比率.
- 在5年后,不增长的生存率为<25%的增长率为31%,增长率为≥100%的增长率为6%.
结论:
- 最初的体积增长率是一个可靠的分层工具,用于种植零星的VS.
- 瘤生长率,而不是年龄或初始体积,预测了攻击性行为.
- 在初始生长检测之前,几乎所有体积翻了一番的瘤都会进一步生长或需要治疗.

Tumor Progression
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...

Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Cancer Survival Analysis
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...
