概括
对于患有低风险疾病的差异化甲状腺癌 (DTC) 幸存者,在甲状腺切除术后保持血清甲状腺激素 (TSH) 水平在 2-4 mIU / L 之间,与较低水平一样安全. 较高的TSH水平 (>4mIU/L) 与复发风险增加有关.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 甲状腺学 甲状腺学
背景情况:
- 利沃甲状腺素治疗用于抑制甲状腺激素 (TSH) 在分化甲状腺癌 (DTC) 患者的甲状腺切除术后.
- 指南建议TSH水平为0.5-2mIU/L,用于低风险的DTC,但证据有限.
- 更高的TSH抑制 (<0.5 mIU/L) 可能有利于更高风险的DTC,但会带来风险.
研究的目的:
- 评估血清TSH水平在高正常范围 (2-4 mIU/L) 与低正常范围 (0.5-2 mIU/L) 和甲状腺切除术后DTC复发之间的关联.
- 评估不同TSH目标范围的低风险DTC患者的复发风险.
主要方法:
- 一项基于人口的回顾性队列研究,使用加拿大安大略省 (2007-2018) 的行政卫生数据.
- 包括26336名患有甲状腺切除术后DTC的患者.
- 用多变量因特定的比例危险回归分析来确定DTC复发的时间,定义为重复手术,放射性治疗或DTC特定的死亡.
主要成果:
- 在0.5-2 mIU/L和2-4 mIU/L的TSH水平之间没有观察到DTC复发的显著差异.
- 暴露于TSH水平>4mIU/L与DTC复发的显著增加有关 (调整后的csHR为1.07).
- 在基线治疗组中,结果保持一致.
结论:
- 对于低风险的DTC患者,在甲状腺切除术后保持TSH水平在0.5-2 mIU/L或2-4 mIU/L之间,在临床上显著的复发中没有差异.
- 目前的指导方针可能会考虑更自由的TSH目标范围,用于低风险的DTC队列.
- 这些发现不适用于高风险的DTC患者.

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...

Cancer Stem Cells and Tumor Maintenance
4.7K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
