科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 精准医学是一门精准的医学.
背景情况:
- 在日本,对于先进的固体瘤,全面基因组分析 (CGP) 得到了补偿.
- 罕见的鼻癌亚型的基因组数据有限,阻碍了向治疗.
研究的目的:
- 描述复发性/转移性鼻癌亚型中的遗传突变特征.
- 为了确定鼻癌的预后基因组变化.
主要方法:
- 使用FoundationOne CDx下一代测序对135例鼻癌病例的分析.
- 数据来源于日本国家基因组分析数据库 (2019年6月 - 2025年5月).
- 使用日志等级测试和考克斯比例危险模型进行生存分析.
主要成果:
- 在所有亚型中,TP53和KMT2D突变是常见的.
- 在状细胞癌 (SCC) 中,KMT2D,EGFR和RICTOR突变与预后不佳相关.

Cancers Originate from Somatic Mutations in a Single Cell
15.0K
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...

Cancer
54.8K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
