Further analysis on the clinical correlation of LDH with OS and DFS of PAAD patients showed that patients with high expression of LDHA mRNA expressions are associated with poorer OS and DFS (HR = 2.2, P = 0.00028; HR = 2.1, P = 0.00087, respectively) (Figure S1B). This evidence concerns the gene LDHA and pancreatic adenocarcinoma.
