概括
像PD-L1和CD8+T细胞这样的免疫细胞在复发后在卵巢清细胞癌中增加. 复发后这种免疫微环境的转变需要进一步调查免疫疗法选择.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 基因组学就是基因组学.
背景情况:
- 卵巢清细胞癌 (OCCC) 中的瘤免疫微环境 (TME) 仍然定义不佳.
- 了解从未接受过治疗到复发的TME动态对于与临床结果相关性至关重要.
研究的目的:
- 在高级阶段的OCCC中对TME进行表征.
- 分析从未接受治疗到复发的免疫变化.
- 为了将TME特征与临床结果相关联,包括敏感性.
主要方法:
- 免疫组织化学被用来评估编程细胞死亡连接体1 (PD-L1),CD8+ T细胞,Foxp3+ T细胞和瘤透淋巴细胞 (TILs).
- 进行了下一代测序,以确定常见的基因组变化.
- 分析包括54名晚期OCCC患者,比较治疗前和复发样本.
主要成果:
- 在复发后,PD-L1和CD8+T细胞表达显著增加 (分别为p=0.048和p=0.022).
- 在治疗阶段之间没有发现TIL密度或Foxp3+T细胞的显著差异.
- PIK3CA和ARID1A突变很常见 (每种为41.7%),但与免疫学变化或生存无关.
- 在复发的敏感性疾病中观察到更高的TIL表达.
结论:
- 晚期OCCC中的TME在复发后显示出显著的变化,PD-L1和CD8+T细胞表达增加.
- 这些发现凸显了研究TME调制在复发性OCCC中免疫疗法选择的潜力的需要.
- 需要进一步的研究来探索这些免疫微环境变化的治疗影响.

02:17The Tumor Microenvironment
6.6K
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...

02:07Tumor Progression
6.3K
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...

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
