概括
在放射性治疗前刺激的甲状腺蛋白 (RAI Tg) 水平预测了差异化甲状腺癌 (DTC) 的治疗反应. 在RAI前的Tg切断值为7.55 ng/ml有效地识别出患者对治疗的初始反应很好.
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:
- 甲状腺蛋白 (Tg) 是监测差异化甲状腺癌 (DTC) 的关键生物标志物.
- 评估早期治疗反应对于管理DTC持续性和复发风险至关重要.
研究的目的:
- 评估在放射性治疗前刺激Tg (RAI前Tg) 和DTC中的初始治疗反应之间的相关性.
- 为确定RAI前Tg的预测性切断值,以确定一个优秀的初始响应.
主要方法:
- 对166名接受全甲状腺切除术和放射性治疗的DTC患者进行了回顾性队列研究.
- 治疗反应被分类为优秀 (ER),不确定的 (IndR) 或不完整 (IncR) 治疗后6-24个月.
- 接收器操作特征 (ROC) 曲线分析以确定RAI前Tg截止值.
主要成果:
- 与IndR和IncR相比,较低的RAI前Tg水平与优异反应 (ER) 有显著的关联 (p<0.001).
- 在RAI前的Tg切线为7.55ng/ml,在将ER与其他反应组区分开来时显示出高准确度 (AUC0.832).
- 多变量分析确定了ATA低风险状态和RAI前Tg<7.55 ng/ml作为ER的独立预测因素.
结论:
- 前RAI Tg水平是DTC患者初始治疗反应的有价值的预测指标.
- 确定的RAI前Tg切线为7.55ng/ml,可以帮助识别可能达到优异反应的患者.
- 预RAI Tg是早期治疗评估和DTC管理中的患者随访的重要工具.

Synthesis and Regulation of Thyroid Hormones
4.5K
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 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...
