KRAS and colorectal carcinoma: Exceptional performance for both CRC (sensitivity and specificity) and APL (sensitivity) was displayed by biomarker panels including methylated SDC2 with methylated SFRP1/2 (CRC: 91.5%/97.3%, APL: 89.2%) or methylated TFPI2 (CRC: 94.9%/98.1%, APL: 100%), and a 5-biomarker panel of mutational targets APC, Bat-26, KRAS, L-DNA, and p53 (CRC: 91.0%/93.0%, APL: 82.0%).
