概括
显著的结节生长 (SNG) 在10年多的良性甲状腺结节中很常见. 患有多个较小的结节的年轻患者更有可能生长,但恶性瘤仍然很少见,支持灵活的随访.
科学领域:
- 内分泌学 在内分泌学.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 无症状的甲状腺结节很常见,大多数是良性的.
- 经常观察到显著的结节生长 (SNG),需要根据指南进行重新评估.
- 在良性甲状腺结节中对SNG和恶性瘤风险的长期数据有限.
研究的目的:
- 为了确定10年内良性甲状腺结核中SNG相关的速率和因素.
- 为了比较基于直径和基于体积的标准来评估SNG.
- 评估SNG与恶性瘤风险之间的长期关联.
主要方法:
- 在376名无甲状腺患者的10年内对732个良性甲状腺结节进行了回顾性队列研究.
- 在基线,5年和10年使用以直径为基础的 (DBC) 和以体积为基础的 (VBC) 标准评估结节大小.
- 一般化的线性混合效应模型分析了影响SNG的因素 (年龄,性别,结节数,初始TSH,体积,回声性,定位).
主要成果:
- 在VBC中,SNG的发生频率高于DBC (10年后的35%),而不是VBC (10年后的44%).
- 与SNG相关的因素包括年龄较小 (<45岁),结节数较多,初始结节体积较小.
- 恶性瘤很少见 (0.5%在原始结节中,1.4%在活检中),尽管观察到生长.
结论:
- 在长期随访期间,良性甲状腺结节的显著结节生长是常见的.
- 基于体积的标准比基于直径的标准更有效地检测成长.
- 在生长的良性结节中恶性瘤的风险很低,这表明灵活的随访协议是实际的.

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

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...
