Abstract
New technologies have enabled faster, cheaper and more accurate genomic and other types of profiling. Therefore, treatment has become more customized according to molecular subtype. Here, we summarize the current status of genomic profiling for colorectal cancer (CRC) and discuss future directions. Recently, the CRC Subtyping Consortium classified CRC into four subtypes: CMS1, microsatellite instability immune (14%); CMS2, canonical (37%); CMS3, metabolic (13%); and CMS4, mesenchymal (23%). Testing for KRAS, NRAS and BRAF mutations, and microsatellite instability status in CRC has proven essential for treatment decisions. Tumor heterogeneity and the evolution of drug-resistant subclones after therapy should be further assessed and pursued. Patient-derived xenografts and liquid biopsies might facilitate the development of optimum and accurate personalized therapy regimens.
期刊介绍：
Colorectal cancer is a major cause of morbidity and mortality, particularly in the developed world. Risk factors for colorectal cancer are on the rise in many countries; populations are aging, and obesity and diabetes are increasing. National screening programs are helping to detect cancer while it is still curable; however, colorectal cancer remains the third leading cause of cancer deaths in the USA and options are still limited for those with more advanced disease. Consequently, colorectal cancer is a major research priority for government, pharmaceutical companies and non-profit organizations. Research into diagnosis and optimum treatment of the disease is progressing rapidly, with new advances reported every day. Colorectal Cancer presents reviews, analysis and commentary. on all aspects of colorectal cancer.
