A representative case of colon cancer with the aberrant methylation of the p16 and E-cadherin genes. A conventional colonoscopy revealed an elevated lesion (A). AFI detected the lesion as a strong magenta area (B). A high N/C ratio (0.67) was observed on the histological specimen of the lesion, which was diagnosed to be a cancer in situ (C). MS-PCR showed the aberrant methylation of the p16 and E-cadherin gene promoters (D).
