概括
甲状腺癌的放射性治疗在100mCi或更低的累积剂量下是安全的,没有增加第二次原发性恶性瘤的风险. 较高剂量以剂量依赖的方式增加癌症风险,需要仔细考虑风险和益处.
科学领域:
- 在瘤学瘤学.
- 核医学就是核医学.
- 流行病学 流行病学
背景情况:
- 甲状腺癌是一种常见的内分泌恶性瘤.
- 放射性 (RAI) 治疗是差异化甲状腺癌的标准治疗方法.
- 在RAI治疗后出现二次原发性恶性瘤的风险需要彻底调查.
研究的目的:
- 调查放射性 (RAI) 治疗与甲状腺癌患者第二次原发性恶性瘤风险之间的关联.
- 为了比较二次原发性恶性瘤的风险,用RAI治疗的患者与单独手术治疗的患者.
主要方法:
- 利用韩国国家健康保险服务 (NHIS) 数据库,覆盖了整个国民人口.
- 在2004年至2018年期间,确定了363,155名被诊断为甲状腺癌的患者.
- 在接受RAI治疗的队列 (147,674名患者) 和仅接受手术的队列 (215,481名患者) 之间比较了第二次原发性恶性瘤的发生率.
主要成果:
- 在累计RAI剂量高达100mCi (HR,1.013;95%CI,0.979-1.049) 的情况下,没有观察到第二次原发性恶性瘤风险的显著增加.
- 在超过100mCi的累积剂量时,发现了统计学上显著的风险增加:101-200mCi (HR,1.214),201-300mCi (HR,1.422) 和>300mCi (HR,1.693).
- 第二种原发性恶性瘤的风险在较高的累计RAI剂量下呈现出剂量依赖的增加.
结论:
- 总累积剂量为100mCi或更低的RAI治疗对于第二次原发性恶性瘤风险是安全的.
- 对于超过100mCi的RAI剂量,第二次原发性恶性瘤的风险与剂量成比例增加.
- 对于超过100mCi的RAI治疗剂量的临床决定,应仔细权衡益处与增加的二次癌症风险.

Synthesis and Regulation of Thyroid Hormones
4.6K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
95
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
