Prognostic Value of Depdc1 expression in tumor and non-tumor tissue of patients with hepatocellular Carcinoma

Abstract

Background/Aim: To evaluate the impact of DEPDC1 expression on patient prognosis after hepatic resection for hepatocellular carcinoma (HCC). Patients and Methods: We reviewed data from 75 patients who underwent hepatic resection for HCC between 2004 and 2013. Recurrence at 2 years following resection, which mainly included metastatic recurrence, was defined as late recurrence. Results: DEPDC1 was up-regulated in HCC tissue and in non-tumor tissue of patients with HCC compared to normal liver (p<0.01 and p<0.01, respectively). High expression of DEPDC1 was associated with poor overall, disease-specific, and disease-free survival (p=0.02, p<0.01, and p<0.01, respectively). High DEPDC1 expression was an independent predictor of death and recurrence (p=0.03 and p<0.01, respectively). High expression of DEPDC1 in non-tumor liver was an independent risk factor for late recurrence (p=0.04). Conclusion: High expression of DEPDC1 in tumor tissue appears to be associated with tumor progression and poor prognosis.
