ABSTRACT
BACKGROUND: Growing evidence has supported that long non-coding RNAs (lncRNAs) could play vital roles in the development, progression, and prognosis of colorectal cancer (CRC). However, little is known about the clinical significance of BRAF-activated non-coding RNA (BANCR) in CRC. The aim of this study is to explore the clinical value of lncRNA BANCR in CRC patients. METHODS: The expression of lncRNA BANCR was measured in 106 CRC tissues and 65 adjacent normal tissues using the quantitative real-time PCR. RESULTS: The study showed that lncRNA BANCR was highly expressed in CRC tissues compared with adjacent normal tissues (P < 0.001). In addition, high expression of lncRNA BANCR was positively correlated with the lymph node metastasis (P < 0.001). Kaplan-Meier analysis showed that patients with high lncRNA BANCR expression had a shorter overall survival (OS) compared with the low lncRNA BANCR expression group (P = 0.001). Interestingly, for the group of patients with the lymph node metastasis, we found the similar result that high lncRNA BANCR expression was related to poor OS (P = 0.004). Furthermore, the multivariate Cox regression model analysis indicated that high expression of lncRNA BANCR was an independent poor prognostic factor in CRC patients (HR 2.24, 95% CI 1.22-4.16, P = 0.009). CONCLUSIONS: Upregulation of lncRNA BANCR may be associated with the lymph node metastasis and poor survival of CRC. LncRNA BANCR could be served as a novel and useful biomarker for CRC lymph node metastasis and prognosis.
