(C) Kaplan-Meier curve and Log-rank test Astragaloside III indicated high expression of TNF- predicted poor OS of PDAC patients (= 0.013). Furthermore, we investigated the prognostic value of TNF- expression in all pancreatic cancer cases and PDAC cases. Kaplan-Meier analysis and the log-rank test showed that high expression of TNF- in both all pancreatic cancer cases and PDAC cases predicted poor survival (= 0.0061 and 0.013, respectively). In all pancreatic cancer cases, median OS of high TNF- expression subgroup was 10 months (95% CI, 7.96C12.04), while the low TNF- expression subgroup had a median OS of 12 months (95% CI, 3.22C20.78). In univariate analysis, TNM stage, pathological grade, lymph node status, and TNF- level were found to be significantly associated with the OS of all pancreatic cancer patients (= 0.0029, 0.0088, 0.0021 and 0.0071, respectively; Table ?Table1)1) as well as PDAC patients (= 0.0081, 0.0199, 0.009 and 0.0141, respectively; Table ?Table1).1). To determine whether TNF- expression is an independent predictor of pancreatic patients’ survival, a multivariate analysis was performed using COX proportional hazard regression model. TNM stage, pathological grade, and lymph node status were considered as potential confounding factors and were included in the multivariate model.

Taken together, our data revealed that TNF- expression is not only associated with PDAC initiation but also an independent prognosticator of PDAC patients, suggesting the critical values of targeting TNF- in pre-clinical and clinical settings.
