概括
轨道中的孤独纤维性瘤 (oSFTs) 很少转移,但通常会局部复发. 在11%的OSFT病例中发现了端粒酶逆转录酶促进子突变,这表明瘤攻击性行为的潜在预后因素.
科学领域:
- 眼科医生 眼科 眼科
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 孤独纤维性瘤 (SFTs) 是罕见的,轨道SFTs (oSFTs) 是非常罕见的.
- oSFTs具有很高的局部复发率,但很少转移,需要确定预后因素.
- 端粒酶逆转录酶 (TERT) 促进子突变与其他部位的SFTs的预后不佳有关.
研究的目的:
- 调查轨道SFT中TERT促进子突变的流行情况.
- 分析OSFTs中TERT促进子突变的临床 - 组织病理学特征和预后影响.
主要方法:
- 追溯分析了2017年至2021年间诊断的9起OSFT病例.
- 临床 - 组织病理学评估,包括对TERT促进体突变的评估.
- TERT突变状态与瘤行为,复发和转移潜力的相关性.
主要成果:
- 在9例OSFT病例中的1例 (11%的患病率) 中发现了TERT促进器突变.
- 有TERT突变的病例显示中等转移风险和侵略性的局部生长,导致复发和眼睛损失.
- 在6例病例中发生了局部复发或进展;没有观察到远程转移.
- 典型的成像发现包括管状血管结构和降低的明显扩散系数 (ADC).
结论:
- TERT促进子突变可能作为轨道SFTs攻击性行为的预后标志物.
- 在OSFT中11%的TERT突变的患病率与头部和部SFT相似.
- 需要进一步的研究来阐明TERT突变在OSFT管理和治疗策略中的作用.

4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
