まとめ
分化甲状腺癌の治療後,甲状腺刺激ホルモン (TSH) レベルが4mIU/ Lまで上昇すると,患者の3分の1が3年以内にレボチロキシン治療を必要とします. このアプローチは,薬剤を必要としない人では,TSHの有意な増加を招く可能性があります.
科学分野:
- 内分泌学
- 腫瘍学
背景:
- 差別化された甲状腺がん (DTC) の治療には,しばしば甲状腺切除術が必要です.
- 術後の管理戦略は,甲状腺機能を維持し,再発を防ぐことを目的としています.
研究 の 目的:
- 低リスクの甲状腺切除手術の3年後の正常な内生性甲状腺機能の有病率を決定する.
- レボチロキシン置換療法の必要性について,手術後の甲状腺刺激ホルモン (TSH) レベルを最大4mIU/ Lで受け入れることの影響を評価する.
主な方法:
- 東デンマークのDTC治療を受けた162人の患者の遡及レビュー.
- 術後のTSH値が4mIU/ L未満の患者はレボチロキシンなしで追跡した.
- 収集されたデータには,レボチロキシンの開始,TSHレベル,再発,および残留葉の結節性が含まれています.
主要な成果:
- 88%の患者は手術前にはレボチロキシンを必要としなかった.
- 甲状腺の内在的な正常な機能は1年後の80%から3年後の66%まで低下した.
- 甲状腺機能低下症 (TSH>4. 0mIU/ L) は34%の患者で3年後に発症し,レボチロキシン治療が必要となった.
- レボチロキシンを受けていない患者では,TSH濃度が正常範囲内で3年間にわたって有意に増加した (p< 0. 0001).
- 再発は認められず,ノドルの成長による完全甲状腺切除手術は3%であった.
結論:
- 甲状腺切除術後3年,TSHの値が4mIU/ Lに達すると,約3分の1のDTC患者はレボチロキシン治療を必要とします.
- このコホートにおけるレボチロキシンの治療を避けると,TSHレベルが著しく上昇します.

Synthesis and Regulation of Thyroid Hormones
5.1K
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...

Functions of Thyroid Hormones
3.2K
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...

The Thyroid Gland
4.3K
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...
