主要方法:
- 针对680个基因小组的下一代测序 (NGS) 对来自244名中国患者的321个瘤样本进行了针对性测序.
- 分析了体质突变概况,并在膀,脏和前列腺癌类型中进行了比较.
- 基因组数据与已建立的西方队列 (例如,MSK-IMPACT) 进行了比较.
主要成果:
- 根据癌症类型 (膀13.89%,脏10.00%,前列腺4.55%) 的PD-L1阳性程度有所不同.
- 经常发生突变的基因包括VHL,TP53,KMT2D,KMT2C和TERT.
- 观察到特定基因 (例如,膀癌中的TP53,CCNE1) 和PD-L1表达之间存在显著的相关性.
- 对比分析显示了中度的基因重叠,但与西方队列的频率一致性较弱,表明了特定于人群的基因组差异.

Nursing Assessment of the Genitourinary System I: Health History
348
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

Cancers Originate from Somatic Mutations in a Single Cell
14.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Loss of Tumor Suppressor Gene Functions
5.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
