CCDC26 and pancreatic neoplasm: We also analyzed other biomarkers related to PaCa survival performance and found that LINC02325 (AUC = 0.80), FNDC1-AS1 (AUC = 0.76), ZEB2-AS1 (AUC = 0.75) had a predictive effect on the 5-year survival prognosis of pancreatic cancer compared with the AUC of these candidate biomarkers, such as LINC01638 (AUC = 0.58), ABHD-AS1 (AUC = 0.61), CCDC26 (AUC = 0.57), HULC (AUC = 0.57), and other miRNAs (miR-25-3p, miR-210-3p, miR-221-3p, and miR-19a-3p) (AUC = 0.53 - 0.62) (Table 3).
