概括
甲状腺蛋白 (Tg) 截止值为0.2 ng/mL,有效排除了分化甲状腺癌患者手术后的结构性疾病. 这一发现甚至适用于没有接受放射性切除的患者,有助于监测持续或复发的DTC.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 临床化学 临床化学
背景情况:
- 血清甲状腺蛋白 (Tg) 是甲状腺切除术后监测差异化甲状腺癌 (DTC) 的关键生物标志物.
- 在图像上显现结构性疾病 (SD) 之前,Tg可以检测持续或复发的DTC.
研究的目的:
- 为了评估Elecsys® Tg II测试在0.2 ng/mL切割值的性能,以排除DTC后甲状腺切除术患者中SD的成年人.
- 为了评估测试的实用性与或没有放射性移除 (RAI).
主要方法:
- 使用了两个患者队列:纵向 (Tg在TSH抑制下每两年评估一次) 和横截面 (Tg在确诊SD患者中评估一次).
- 对联合队列和纵向队列进行了分析,包括RAI治疗和非RAI治疗的子组.
主要成果:
- 具有0.2 ng/mL截止值的Elecsys Tg II试验显示,排除SD的负预测值为99.9%.
- 该试验显示高灵敏度 (98.5%-100%) 和可接受的特异性 (53.4%-53.5%) 检测SD.
- 在两个队列和RAI治疗与非RAI治疗的患者中,表现一致.
结论:
- 0.2 ng/mL的Tg截止值对于排除TSH抑制下的甲状腺切除术后DTC患者的SD非常有效.
- 这种切断值即使在没有接受RAI治疗的患者中也是可靠的,支持其临床实用性.

Synthesis and Regulation of Thyroid Hormones
4.7K
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
4.0K
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
2.8K
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...
