概括
对于差异化甲状腺癌 (DTC) 患者来说,治疗后一年没有甲状腺蛋白抗体 (TGab),无法检测的甲状腺蛋白 (TG) 水平 (<0.5 ng/mL),表明复发风险非常低. 这表明,对这些人来说,可能不需要扩大监测.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 医学诊断 医学诊断 医学诊断
背景情况:
- 差异化甲状腺癌 (DTC) 管理涉及长期治疗后监测.
- 基于早期反应标志物的监测持续时间优化对于患者护理和资源分配至关重要.
研究的目的:
- 通过使用1年治疗后的铁血球蛋白 (TG) 和铁血球蛋白抗体 (TGab) 水平来确定DTC治疗的优异反应.
- 根据这些早期标志物,为DTC患者提供适当的监测时间.
主要方法:
- 在手术治疗后,使用标准监测协议跟踪DTC患者,有或没有放射性治疗.
- 在治疗后1年的甲状腺蛋白 (TG) 和甲状腺蛋白抗体 (TGab) 水平将患者分为三个队列:不可检测的TG (<0.5 ng/mL),可检测的TG (≥0.5 ng/mL) 和正的TGab (>1 IU/mL).
- 结构性复发率和TG/TGab水平趋势在这些队列中进行了比较.
主要成果:
- 在治疗后1年,在268名DTC患者中,78%的患者有不可检测的TG,11%的患者有可检测的TG,11%的患者呈阳性TGab.
- 在无法检测TG的患者中,结构性复发率显著降低 (1%对38%可检测TG和13%对阳性TGab).
- 在1年内无法检测的TG的高比例患者在随访期间保持了不可检测的水平,而一些可检测的TG或阳性TGab的患者在没有进一步治疗的情况下显示正常化.
结论:
- 一年后的DTC治疗,TG水平<0.5 ng/mL在没有TGab的情况下,与极低的复发风险有关.
- 这些发现表明,对于DTC患者在1年内达到无法检测的TG和TGab的患者,可能不需要扩展监测.
- 使用TG和TGab水平进行早期风险分层可能会个性化DTC监控策略.

Synthesis and Regulation of Thyroid Hormones
4.7K
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
3.9K
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...
