概括
放射性疗法 (RAIT) 剂量不会显著影响乳头甲状腺癌 (PTC) 发生的复发或副作用,淋巴结转移 (N1). 在N1 PTC患者中,较高的RAIT剂量 (≥150mCi) 与较低的剂量 (<150mCi) 没有额外的益处.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 核医学是一种核医学.
背景情况:
- 带有区域淋巴结转移 (N1) 的乳头甲状腺癌 (PTC) 需要有效的治疗策略.
- 放射性疗法 (RAIT) 是一种标准治疗方法,但对N1疾病的最佳剂量仍在争论中.
研究的目的:
- 研究放射性疗法 (RAIT) 剂量对N1乳头甲状腺癌 (PTC) 患者的存活率和复发率的影响.
- 为了比较接受高剂量 (≥150 mCi) 与低剂量 (<150 mCi) RAIT的N1 PTC患者之间的结果.
主要方法:
- 对81名N1 PTC患者的回顾性分析,这些患者在2007-2011年间在高等学术医院接受治疗.
- 患者根据RAIT总剂量进行了分层:<150mCi (低剂量) 与≥150mCi (高剂量).
- 评估结果包括复发,死亡率和即时的RAIT副作用,随访时间中位数为9年.
主要成果:
- 对于N1a和N1b PTC,在高剂量和低剂量RAIT组之间没有观察到复发率或即时RAIT副作用的统计学上显著差异.
- 在N1a组中没有记录死亡率,在N1b PTC中,在高剂量和低剂量RAIT之间没有发现死亡率的显著差异.
- 低事件率限制了最终的解释,特别是N1b死亡率和副作用.
结论:
- 目前的RAIT剂量方案 (≥150mCi vs <150mCi) 在减少N1a或N1bPTC复发方面没有显著的益处.
- 两种RAIT剂量策略之间没有发现死亡率或即时副作用的显著差异.
- 需要进行进一步的大型随机试验,以确定N1 PTC患者的最佳,个性化的RAIT剂量.

Biological Effects of Radiation
15.3K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
86
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...
