We identified many genes that are differentially expressed between the long and short survival-time groups in group B, some of which have previously been found to be altered in pancreatic cancer such as ZNF345, ZNF280B, UNC45B, ZFYVE9, DGKD, PDPN, OLA1, SORBS1, PTPN20A, PTPRA, EYA2, and BCAS4 (according to the Pancreatic Expression and Pancreatic Cancer Databases). Here, ZNF280B is linked to familial pancreatic carcinoma.
