COMMD2 and pancreatic adenocarcinoma: Moreover, the relationship between COMMD2 expression and DSS was determined by Cox regression analysis, which showed that enhanced COMMD2 expression had a negative impact on survival in patients with PAAD (p < 0.001), LIHC (p < 0.001), LGG (p < 0.001), ACC (p = 0.02), and LUAD (p = 0.03) (Figure S2B).
