Abstract
Colorectal cancer is a highly heterogeneous tumor. The study of intra-tumor heterogeneity (ITH) can not only explore the evolutionary process of tumors, it can also solve the problems of resistance and recurrence caused by heterogeneity in patients with advanced colorectal cancer. However, the multi-region sampling is difficult and the quantitative indicators of ITH are not consistent, the research on ITH is still controversial. This article reviews the detection of ITH and the significance of ITH in tumor evolution and clinical applications.
Key words:
Colorectal cancer; Intra-tumor heterogeneity
