概括
甲状腺指南Px基因组分类器识别了低风险的乳头甲状腺癌 (PTC) 亚型 (类型1和2),复发率低. 高细胞变体PTC,特别是3型,出现更高的复发率,表明具有侵略性生物学.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 分子病理学分子病理学
背景情况:
- 乳头甲状腺癌 (PTC) 的高细胞变体与经典变体相比的预后较差.
- 甲状腺指南Px是一个基因组分类器,使用细针吸入样本将PTC分类为三种分子亚型.
- 第1类和第2类通常表现出较低的复发率,特别是在早期瘤 (1-4厘米和N0) 中,而第3类与攻击性行为和高的复发率有关.
研究的目的:
- 调查高细胞变异组织学与甲状腺指南Px分类器在乳腺甲状腺癌中提供的风险分层之间的相互作用.
- 评估高细胞变体在不同分子亚型和PTC阶段存在的临床影响.
主要方法:
- 来自736名患者的基因表达数据使用甲状腺指南Px分类器进行了分析.
- 乳头甲状腺癌病例被分类为"早期" (瘤大小1-4厘米和N0) 或"晚期".
- 结构性复发是主要终点;转录组和基因组分析探索了高细胞变体和非高细胞变体PTC之间的生物学差异.
主要成果:
- 甲状腺指南Px将369个早期PTC分为1型 (35%),2型 (45.5%) 和3型 (19.5%),其复发率分别为3.9%,1.9%和19.4%.
- 高细胞变异在早期的2型PTC中不常见 (4.2%),但没有出现复发;然而,它们在先进的2型PTC中更频繁 (10.2%,P=.04).
- 在3型PTC中,高细胞变异在晚期瘤中显示出明显更高的复发率 (50%与非高细胞变异的28.6%相比,P=.01) 并与增加的细胞增殖,入侵和炎症有关.
结论:
- 甲状腺指南Px有效地识别了适合保守管理的低风险子组 (早期的1型和2型PTC).
- 高细胞变异在这种低风险组中很少见,并且没有复发;然而,它们似乎会增加3型PTC复发风险,特别是在晚期.
- 这项研究强调了基因组分类在细化乳头甲状腺癌风险评估中的有用性,特别是在考虑特定的组织学变异时,如高细胞类型.

Synthesis and Regulation of Thyroid Hormones
4.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

The Thyroid Gland
3.6K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones
2.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Tumor Progression
6.2K
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...
