Abstract:
Colorectal cancer is the third most lethal cancer in men and women in the USA. Although surgical resection is the mainstay of treatment, many patients develop local and widely metastatic disease and become resistant to conventional chemotherapeutics. Recent comprehensive molecular characterization has led to subclassification of colorectal adenocarcinoma based on molecular properties, such as microsatellite instability and high CpG island methylation. These emerging subclassifications are associate with varying frequencies of RAS, BRAF, APC and other genetic events and have the ability to redefine therapeutic regimens. In this review, we examine how molecular diagnostics are currently used while providing insight into emerging implications for molecular analysis for personalized therapy in colorectal cancer.
