OBJECTIVE: Previous study has reported that long noncoding RNA AK001796 (AK001796) functions as a tumor promoter in esophageal squamous cell carcinoma (ESCC). However, its clinical in ESCC patients remains largely unclear. The purpose of the present study was to evaluate the prognostic value of AK001796 in ESCC patients.

PATIENTS AND METHODS: The expression levels of AK001796 in ESCC tissues and matched normal tissues were detected by RT-PCR. Association between AK001796 levels and clinicopathological factors was also analyzed by chi-square test. Overall survival (OS) and disease-free survival (DFS) were analyzed using the Kaplan-Meier method and log-rank test. The predictors for OS and DFS were assessed by univariate analysis and multivariate analysis using Cox’s proportional hazards model.

RESULTS: We found that AK001796 was elevated in human ESCC samples compared with the adjacent normal tissues (p<0.01), and the high level of AK001796 expression was significantly correlated with lymph node metastasis (p=0.032) and advanced UICC stage (p=0.016). Interestingly, Kaplan-Meier analysis indicated that patients with high AK001796 expression had a significantly lower OS (p=0.010) and DFS (p=0.001). Moreover, we showed that AK001796 was an independent poor prognostic factor for OS and DFS in ESCC patients through univariate and multivariate analysis.

CONCLUSIONS: Our data provide important evidence that AK001796 may be a useful biomarker of advanced progression and poor prognosis of ESCC.
