Abstract |
We have previously shown that aberrant promoter methylation of ZNF331 is a potential biomarker for colorectal cancer detection with high sensitivity (71%) and specificity (98%). This finding was recently confirmed by others, and it was additionally suggested that promoter methylation of ZNF331 was an independent prognostic biomarker for colorectal cancer (nā=ā146). In the current study, our initial colorectal cancer sample series was extended to include a total of 423 cancer tissue samples. Aberrant promoter methylation was found in 71% of the samples, thus repeatedly suggesting the biomarker potential of ZNF331 for detection of colorectal cancer. Furthermore, multivariate Cox's analysis indicated a trend towards inferior overall survival for colorectal cancer patients with aberrant methylation of ZNF331. |
