概括
甲状腺癌手术后未刺激的甲状腺蛋白 (Tg) 水平预测了复发风险. 监测Tg趋势,而不仅仅是单个值,可以改善对未接受放射性治疗的差异化甲状腺癌患者的风险评估.
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:
- 在没有放射性 (RAI) 治疗的情况下进行全甲状腺切除术后,未经刺激的血清甲状腺蛋白 (Tg) 对差异化甲状腺癌 (DTC) 复发的预后值尚不清楚.
- 在低至中等风险的DTC患者中需要精细化风险分层.
- 评估动态Tg监控与静态切断值并行至关重要.
研究的目的:
- 确定最佳的非刺激血清甲状腺蛋白 (Tg) 切割值,以预测DTC患者的结构性复发.
- 评估动态Tg监控在风险分层中的作用.
- 评估当前韩国甲状腺协会 (KTA) 指南的临床相关性.
主要方法:
- 对9753名低至中等风险的DTC患者进行了回顾性分析,这些患者接受了没有RAI的全甲状腺切除术.
- 6,12和24个月后,在甲状腺激素抑制下 (<2mIU/L) 测量血清Tg. 手术后.
- 使用高灵敏度测试;通过ROC曲线和生存分析确定最佳Tg切线.
主要成果:
- 较高的非刺激Tg水平始终预测结构性复发,最佳切断值为0.3 ng/mL.
- Tg ≥0.2 ng/mL (KTA生化缓解截止值) 显示出对复发的高度敏感性.
- 6个月后Tg ≥5.0 ng/mL (KTA生化不完全响应) 独立预测了复发风险升高;Tg动力学随着时间的推移也表明了复发风险.
结论:
- 非刺激的Tg水平与DTC患者在没有RAI的甲状腺切除术后的结构性复发风险密切相关.
- 目前的KTA切割值 (0.2 ng/mL和5.0 ng/mL) 是临床相关的.
- 序列Tg评估和Tg动力学显著提高了这一患者群体的风险分层.

Synthesis and Regulation of Thyroid Hormones
7.0K
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
6.5K
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...
