Abstract: We analysed clinical and methylation data from 184 pancreatic tumor samples from The Cancer Genome Atlas (TCGA) to assess the relationship between CpG island methylator phenotype (CIMP) and the survival. A classification with the k-means algorithm found 50 tumor samples with higher average levels of methylation (CIMPH) and 56 tumor samples with lower average levels of methylation (CIMPL). We analysed the survival curve for the both groups with the Kaplan-Meier estimate and found that they have different survival functions, having CIMPH worse survival. A differential methylation analysis identified 4916 CpG sites with aberrant hypermetilation, 1423 candidate genes to be markers for diagnostic of pancreatic cancer. These results can help to refine existing CIMP subtypes of pancreatic cancer and its relation with survival.
