  1. The proportion of patients whose differences in CpG island methylation levels are significantly different between healthy tissues and cancer tissues was calculated along with the average methylation levels in healthy tissue or tumors and their difference in values. According to our criteria, we found 35 hypermethylated CpG islands and five hypomethylated CpG islands in tumors. McoM the mean of control (healthy) methylation, McaM the mean of case (cancer) methylation.
