摘要
BACKGROUND: Long noncoding RNA ultraconserved element 338 (uc.338) is a long non-coding RNA reported to function as a promoter in non-small cell lung cancer (NSCLC). However, the function and potential mechanism of uc.338 in NSCLC is still unclear. @@@ OBJECTIVE: The aim of the present study was to assess the effect of uc.338 on the prognosis of patients with NSCLC. @@@ METHODS: The expression levels of uc.338 in NSCLC tissues and matched normal lung tissues were examined by real-time quantitative PCR. Then the association between uc.338 levels with clinical variables as well as survival time was investigated. @@@ RESULTS: We found that uc.338 expression levels were significantly upregulated in NSCLC compared with the matched noncancerous lung tissues (P < 0.01). In addition, increased uc.338 expression was significantly associated with TNM stage (P < 0.003), lymph node metastasis (P < 0.006) and distant metastasis (P < 0.002). More importantly, Kaplan-Meier survival analysis demonstrated that higher uc.338 expression levels were associated with a shorter overall survival (P < 0.0016) and disease-free survival (p < 0.0001) in NSCLC patients. Finally, univariate and multivariate Cox regression analyses revealed that uc.338 was an independent risk factor for overall survival and disease-free survival. @@@ CONCLUSIONS: Our results show that uc.338 may play an important role in tumorigenesis and progression and could serve as a potential independent prognostic biomarker for patients with NSCLC.
