Tumor Progression

Tumor Progression

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...

科学领域:

神经瘤学神经瘤学
分子病理学分子病理学
临床研究临床研究

背景情况:

膜瘤 (EPN) 是一种具有明显分子亚型的异质瘤.
目前对不同EPN亚型的复发模式的理解是有限的.
这种异质性需要对疾病复发进行亚型特定分析.

研究的目的:

为了全面描述分子定义的表瘤亚型的复发模式.
为了将DNA甲基化和拷贝数量改变与临床复发信息相关联.
为未来的临床试验设计和EPN的治疗策略提供信息.

主要方法:

分析了来自欧洲和北美队伍的269例复发性内膜瘤病例.
分子数据 (DNA甲基化,副本数量改变) 与临床数据的相关性.
按分子亚型进行分层:PF-EPN-A,ST-EPN-ZFTA,PF-EPN-B,PF-EPN-SE,以及ST-EPN-YAP.

主要成果:

在EPN亚型中观察到复发时间,转移模式和脊髓干扰的显著差异.
虽然PF-EPN-B和PF-EPN-SE的复发时间较晚,但复发后存活率 (PRS) 不同.
在ST-EPN-YAP和PF-EPN-SE中,没有远程复发;在复发时,ST-EPN-YAP患者通过放射治疗成功挽救.

结论:

膜瘤复发模式是实体特定的,影响临床结果.
临床试验,监测和诊断应该纳入这些亚型特定的复发特征.
个性化方法对于优化EPN管理至关重要.
