概括
端粒酶逆转录酶促进体 (TERTp) 突变表明具有侵略性的脑膜瘤. 所有TERTp突变瘤都复发,突出显示了需要分子标记物来改善这些脑瘤的预后和管理.
科学领域:
- 神经外科 神经外科
- 在瘤学瘤学.
- 分子病理学分子病理学
背景情况:
- 仅靠自身病理学是不足以识别攻击性脑膜瘤的.
- 目前正在探索分子标记物,以补充世卫组织的分级系统.
- 在不同患者群体中验证遗传标记是非常重要的.
研究的目的:
- 评估脑膜瘤中端粒酶逆转录酶促进子 (TERTp) 突变的预后价值.
- 确定TERTp突变状态是否可以预测瘤复发和进展.
主要方法:
- 在2010-2015年间对71名患有1级和2级脑膜瘤的患者进行了回顾性分析.
- 所有患者的最低随访时间为2年.
- 在瘤样本中分析TERTp突变状态.
主要成果:
- 在7.04%的患者中检测到TERTp突变.
- 所有具有TERTp突变的脑膜瘤 (100%) 在随访期间复发.
- TERTp突变与较短的无进展生存时间 (28.20个月与93.18个月) 有显著的关联.
结论:
- TERTp突变是脑膜瘤中攻击性行为的强有力的指标.
- 像TERTp突变这样的分子标记可以帮助完善世卫组织分级系统.

The Retinoblastoma Gene
4.2K
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,...

Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
