概括
微卫星不稳定性高 (MSI-H) 的结直肠癌 (CRC) 在老年人中很常见,挑战了基于年龄的查. 建议根据年龄或临床标准进行系统查,以确保全面的MSI-H CRC检测.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 癌症查 癌症查
背景情况:
- 临床指南建议微卫星不稳定性 (MSI) 查结直肠癌 (CRC).
- 微卫星不稳定性高 (MSI-H) 的CRC在老年患者群体中很普遍.
- 目前基于年龄的查可能会错过大量的MSI-H CRC病例.
研究的目的:
- 为了调查MSI-HCRC在未经选择的人群中的患病率.
- 根据年龄切线 (50岁和60岁) 分析MSI-H CRC的流行情况.
- 评估基于年龄的查算法对MSI-H CRC的有效性.
主要方法:
- 对343名接受了激进CRC手术的患者进行了回顾性分析.
- 使用免疫组织化学 (IHC) 进行的MSI测试.
- 基于年龄的分析使用阿姆斯特丹II (≤50岁) 和修订的贝塞斯达 (≤60岁) 标准.
主要成果:
- 总体MSI-HCRC患病率在队列中为18.7% (平均年龄70岁).
- 使用50年截止时间,MSI-HCRC患病率为22.5% (≤50) 和18.2% (>50).
- 使用60年截止时间,MSI-HCRC患病率为12.6% (≤60) 和20.6% (>60).
结论:
- 基于年龄的MSI-HCRC查可以导致负选择.
- MSI-H CRC在老年患者中很常见,这些患者可能会被基于年龄的算法遗漏.
- 建议对MSI-HCRC进行系统查,以取代基于年龄或临床标准的方法.

Non-LTR Retrotransposons
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...

Mismatch Repair
4.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
