概括
高ATRX表达表明软组织肉瘤 (STS) 的生存率更好. 这一发现表明ATRX是STS患者整体和无转移生存的积极预后指标.
科学领域:
- 在瘤学瘤学.
- 分子病理学分子病理学
背景情况:
- 人们越来越多地认识到ATRX (X链接的α-thalassemia/精神障碍综合征) 和侵袭性肉瘤表型之间的关联.
- 了解预后标志物对于有效的软组织肉瘤 (STS) 管理至关重要.
研究的目的:
- 为了追溯评估ATRX作为软组织肉瘤的预后因素.
- 确定ATRX表达与患者生存结果之间的关联.
主要方法:
- 这是一项对来自单一机构的128种肉瘤的回顾性研究.
- 免疫组织化学染色用于ATRX表达.
- 使用卡普兰-梅尔曲线和考克斯回归分析评估的预后意义在68个初级STS的队列中.
主要成果:
- 高ATRX表达是总生存时间的显著积极预后指标 (HR:0.38,P=0.02).
- 高ATRX表达也预测了改善的无转移生存率 (HR:0.49,P=0.05).
- 这些发现在单变量和多变量分析中都是一致的.
结论:

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
