概括
在甲状腺癌 (TC) 中,BRAF V600E变异与复发有关,特别是在男性和侵袭性瘤中. 在分化CT的风险评估和治疗规划中提供了手术前检测辅助.
科学领域:
- 内分泌学
- 癌症学
- 分子诊断
背景情况:
- 在全球范围内,甲状腺癌的发病率正在上升.
- 在TC中BRAF V600E变异的预后意义仍在争论中.
- 准确的手术前风险分层对于有效的TC管理至关重要.
研究的目的:
- 确定BRAF V600E变种在差异化TC中的预后作用.
- 评估BRAF V600E与无复发生存时间 (RFS) 的相关性.
- 评估BRAF V600E手术前检测对风险分层的有用性.
主要方法:
- 在差异化TC患者中进行了符合STROBE的队列研究.
- 在细针吸收活检细胞块中检测BRAF V600E变异.
- 分析TC复发和RFS作为结果.
- 多变量分析以确定独立的预后因素.
主要成果:
- 这项研究包括87名差异化TC患者,63. 2%患有BRAF V600E变种.
- 在非毛囊亚型中,BRAF V600E与RFS有关.
- 多变量分析确定男性性别,瘤大小,差异化,甲状腺外侵袭,BRAF V600E存在,以及高剂量131I作为降低RFS的独立预测因素.
结论:
- 术前BRAF V600E检测是特定TC患者小组中RFS降低的独立预测指标.
- 与临床因素相结合,BRAF V600E变种有助于进行手术前风险分层.
- 这种模式可以为差异化TC提供个性化治疗策略.

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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
