摘要:
Dysregulation of long non-coding RNAs (lncRNAs) plays critical roles in tumor progression. The purpose of this study was to investigate the relationship between lncRNA CCAT2 expression and cervical squamous cell cancer susceptibility and prognosis.
Expression levels of lncRNA CCAT2 in 123 cervical squamous cell tumor specimens were determined by quantitative real-time PCR (qRT-PCR), to clarify the clinical significance of lncRNA CCAT2 in cervical squamous cell cancer, we further discussed the relationship between lncRNA CCAT2 expression and overall survival (OS) and progression-free survival (PFS).
In the present study, we found that lncRNA CCAT2 was up-regulated in cervical squamous cell cancer tissues compared to the adjacent non-tumor tissues. In addition, the high lncRNA CCAT2 expression was significantly associated with the FIGO stage, lymph node metastasis and depth of cervical invasion (P<0.05). Furthermore, patients with high expression of lncRNA CCAT2 had poor OS (HR=2.813, 95% CI: 1.504-6.172; P=0.017), and PFS rates (HR=3.072, 95% CI: 1.716-8.174; P=0.008). Multivariate Cox proportional hazard model analysis demonstrated that high lncRNA CCAT2 expression was an independent poor prognostic factor for cervical squamous cell cancer patients.
Our study suggested that high expression of lncRNA CCAT2 is related to the prognosis of cervical squamous cell cancer; it may be a new prognostic biomarker and potential therapeutic target for cervical squamous cell cancer intervention.
