Survival curves based on disease free survival (DFS) and overall survival (OS). Survival rate of long-DM (solid line) was significantly low compared to non-DM (fine break line) and short-DM (rough break line) in both DFS (A) and OS (B). Group with CDH1 promoter showed methylation significantly worse DFS (C) and OS (D) in PDC subjects compared to methylation negative group.
