Long noncoding RNA FEZF1-AS1 (FEZF1-AS1) has been showed to involve in a variety of cancers. However, its function and clinical significance in cervical cancer (CC) have not been investigated. The aim of this study was to explore the prognostic value of FEZF1-AS1 in CC patients.


Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to determine the expression level of FEZF1-AS1 in CC specimens and adjacent normal cervical tissues. Association between FEZF1-AS1 expression and clinicopathological characteristics was analyzed x2-test. The Kaplan-Meier method was used to estimate survival curves, and the log-rank statistic was used to test the role of FEZF1-AS1 expression. The possibility of FEZF1-AS1 as a prognostic biomarker for CC was examined by Cox proportional hazard regression model.


We found that FEZF1-AS1 expression levels were significantly higher in CC tissues compared with adjacent non-cancerous tissues (p < 0.01). High expressions of FEZF1-AS1 were significantly association with poorer histological grade (p = 0.004), positive distant metastasis (p = 0.002) and advanced FIGO stage (p = 0.001). Furthermore, patients with low FEZF1-AS1 expression lived shorter than those with high FEZF1-AS1 expression (Log-rank test, p < 0.0034). Cox regression analysis demonstrated that FEZF1-AS1 expression level was an independent prognostic factor for CC overall survival rates (p = 0.008).


We firstly provided clinical evidence that FEZF1-AS1 may be a possible biomarker of poor prognosis in CC.
