Expression of long noncoding RNA NBAT1 is associated with the outcome of patients with non-small cell lung cancer

SUMMARY

OBJECTIVE

Long noncoding RNA neuroblastoma-associated transcript 1 (NBAT1) has been reported to be involved in cancer progression. However, the clinical significance of NBAT1 in non-small cell lung cancer (NSCLC) is still unclear. Our present research aimed to explore whether NBAT1 serves as a biomarker for NSCLC prognosis.

METHODS

The expression of NBAT1 was examined by RT-PCR in tissue samples of 162 NSCLC patients and was compared with the adjacent non-tumor lung specimens. Then the association between NBAT1 expression and clinical-pathological parameters was further evaluated. Survival analysis was performed using the Kaplan-Meier method. The prognostic significance of NBAT1 expression in NSCLC patients was explored by the use of univariate and multivariate analyses.

RESULTS

NBAT1 expression was prominently decreased in NSCLC tissues compared with matched normal lung specimens (p < 0.01). Moreover, survival analyses indicated that patients with low expression displayed dramatically decreased 5-year overall survival (p = 0.008).

CONCLUSIONS

NBAT1 expression might contribute to tumor progression and poor prognosis of NSCLC and might be a new therapeutic target in NSCLC.
