概括
对于低风险的乳头甲状腺癌 (PTC) 患者,手术后的甲状腺刺激激素 (TSH) 水平不会显著影响复发风险. 这表明TSH抑制可能不必要,可能避免并发症.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 甲状腺癌研究研究
背景情况:
- 乳头甲状腺癌 (PTC) 在全球每年影响超过50万个人,大多数病例被归类为低风险.
- 目前的指导方针建议对所有术后PTC患者进行甲状腺刺激激素 (TSH) 抑制,但其在低风险病例中的必要性仍在争论中.
- 现有的建议是经验性的,强调需要大规模的现实世界证据来指导临床实践.
研究的目的:
- 研究手术后的TSH水平与低风险PTC患者的瘤复发之间的关联.
- 提供强有力的,现实世界的证据,以告知TSH抑制在这个患者群体中的有争议的建议.
主要方法:
- 来自中国两大癌症中心的11,140名低风险PTC患者 (2000-2022) 的回顾性研究.
- 术后血清TSH水平被用来计算随访期间的平均TSH.
- 用Kaplan-Meier,log-rank,多变量考克斯回归和两个单边测试 (TOST) 来进行复发分析,并使用倾向分数匹配 (PSM) 来进行混调整.
主要成果:
- 对8991名PSM后患者的分析显示,在不同TSH水平组 (≤0.5, (0.5-1), (1-2), (2-3),>3mU/L) 中,无复发生存 (RFS),局部无复发生存 (LRRFS) 或远程无转移生存 (DMFS) 没有显著差异.
- 多变量考克斯分析表明,抑制TSH和瘤复发之间没有关联 (TSH>2对≤2mU/L:HR=1.30,P=0.23).
- TOST等效测试证实了所有TSH组中瘤复发的统计可比性;亚组分析显示,TSH水平不管其他临床因素如何,都不会影响复发.
结论:
- 手术后的TSH水平与低风险PTC患者的瘤复发无关.
- 蓄意的TSH抑制对于这个群体来说可能是不必要的,可能会避免二次并发症.
- 维持TSH在正常范围内似乎是低风险PTC患者的安全策略.

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...

Functions of Thyroid Hormones
2.5K
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...

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...
