背景情况:
- 胃肠道 stromal 瘤 (GIST) 是一种罕见的介质瘤,起源于胃肠道,最常见的是胃.
- GIST通常是由KIT或血小板衍生的生生长因子受体α (PDGFRA) 的致癌突变驱动的.
- 治疗策略已经取得了显著的进步,特别是对于具有KIT突变的GIST.
研究的目的:
- 审查目前的GIST管理,包括手术切除和辅助意马替尼治疗.
- 讨论高级GIST的治疗前景,重点关注氨酸激酶抑制剂 (TKI) 和新兴的抵抗机制.
- 突出挑战和不断发展的方法来管理缺乏KIT或PDGFRA突变的GIST.
主要方法:

The Tumor Microenvironment
6.5K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Stem Cells and Tumor Maintenance
4.7K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
