Reduction of AZGP1 predicts poor prognosis in esophageal squamous cell carcinoma patients in Northern China.


ABSTRACT: BACKGROUND:As a key regulator in lipid mobilization, AZGP1 has been reported to play a significant role in various cancers. This study was carried out to investigate the role of AZGP1 in the development of esophageal squamous cell carcinoma (ESCC) patients in Northern China. MATERIALS AND METHODS:Through the application of quantitative real-time polymerase chain reaction and immunohistochemical staining, AZGP1 expression in ESCC tissues from Northern China was examined. RESULTS:Decreased expression of AZGP1 was observed in ~60% ESCC patients. AZGP1 downregulation was significantly associated with lymph node metastasis (P=0.035), advanced clinical stage (P=0.018), poor prognosis for 5-year disease-specific survival (DSS; P<0.001), local recurrence-free survival (LRFS; P=0.016), and metastasis-free survival (MeFS; P=0.014). In addition, Cox multivariate analysis revealed that AZGP1 downregulation remained to be an independent prognosticator for shorter DSS (P=0.001), LRFS (P=0.011), and MeFS (P=0.004). CONCLUSION:AZGP1 might be a candidate tumor suppressor and a potential novel prognostic biomarker for ESCC patients in Northern China.
