概括
瘤组织中的CXCR4表达是软组织肉瘤 (STSs) 的有希望的预后因素. 在新辅助治疗后,积极的CXCR4表达预测了突肉瘤和未分化形肉瘤的生存率不佳.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 病理学 病理学 病理学
背景情况:
- 局部化高风险软组织肉瘤 (STSs) 长期生存率不佳.
- 识别新的预后因素对于改善患者的治疗结果至关重要.
- CXCR4,一种化学因受体,在瘤进展,血管新生和转移中发挥作用.
研究的目的:
- 研究瘤组织中CXCR4表达与STS患者的存活率之间的关联.
- 评估CXCR4表达与新辅助疗法反应和患者预后的关系.
主要方法:
- 使用免疫组织化学分析对CXCR4表达的回顾性分析.
- 对连续样本的检查:初始活检,新辅助治疗后的瘤和瘤复发.
- CXCR4表达模式与无复发生存率 (RFS) 和总生存率的相关性.
主要成果:
- 在后新辅助瘤中,阳性细胞质CXCR4表达预测了突肉瘤中较差的RFS (p=0.003) 和整体存活率 (p=0.019).
- 在初始活检中,阳性核CXCR4表达与未分化的多形肉瘤中较差的RFS (p=0.022) 有关.
结论:
- 瘤组织中的CXCR4表达是STS的显著预后因素.
- 在特定的STS亚型中,CXCR4可以作为治疗反应和患者存活率的预测生物标志物.

02:07Tumor 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...
