Major challenges related to tumor biological characteristics in accurate mutation detection of colorectal cancer by next-generation sequencing.

Abstract excerpt

Next-generation sequencing (NGS) has been used in mutation detection of colorectal cancer (CRC). We here interrogated 747 CRC samples to detect mutations in 22 cancer-related genes by using NGS, and to explore some key challenges related to tumor biology. RAS mutations (KRAS or NRAS mutations), RAS/BRAF/PIK3CA mutations (mutations in KRAS, NRAS, BRAF or PIK3CA) and mutation burden (mutations in any of the 22...
