概括

差异化甲状腺癌 (DTC) 患者的低术后甲状腺蛋白 (Tg) 水平预测了结构性复发的风险降低. 这一发现可能有助于识别可能避免放射性 (RAI) 治疗的患者.

科学领域:

内分泌学在内分泌学.
在瘤学瘤学.
核医学就是核医学.

背景情况:

有中等或高复发风险的分化甲状腺癌 (DTC) 患者经常接受放射性 (RAI) 治疗.
血清甲状腺蛋白 (Tg) 水平是手术后和RAI后风险分层的标准,但它们在RAI之前的作用尚不清楚.

研究的目的:

评估非刺激,术后,RAI前Tg水平与中期和高风险DTC患者的持续或复发性结构性疾病之间的关联.
确定RAI前Tg水平是否可以识别可能不需要RAI治疗的患者.

主要方法:

追溯分析来自英国三个癌症中心的301名DTC患者.
收集的数据包括患者特征,未刺激的术后和RAI前Tg水平,以及随访临床/成像结果.
使用单变量和多变量逻辑回归来分析术后Tg与结构性疾病复发/持久性之间的关联.

主要成果:

非刺激的术后Tg是结构性疾病复发/持久性的独立预测因子 (OR 1.016,95% CI 1.005-1.042,p=0.011).
经过ROC曲线分析,术后未刺激的Tg切线值为1.05ug/L.
在21例复发中,有17例 (81%) 的术后Tg水平高于这个截止值.

结论:

低的术后非刺激Tg水平与中期和高风险DTC患者结构性复发的低风险相关.
手术后的Tg水平可能会改善风险分层,可能允许一些患者避免RAI.
需要进行前性试验来验证这些发现.

Synthesis and Regulation of Thyroid Hormones

Synthesis and Regulation of Thyroid Hormones

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

The Thyroid Gland

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

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...
