Association of DPP3 mRNA expression with patient survival in the TCGA dataset of ESCC revealed that DPP3 high expression group exhibits poor OS (P<0.01, Figure 2A) with a median survival of 15.91 months compared with the DPP3 low expression group with a median survival of 41.52 months. Here, DPP3 is linked to esophageal squamous cell carcinoma.
