Low expression of lncRNA MGC27345 is associated with poor prognosis in gastric cancer patients.

OBJECTIVE: A series of evidence showed that long non-coding RNAs (lncRNAs) play an essential regulatory role in the occurrence and development of human cancer, and is a potential biological target in the fight against cancer. PATIENTS AND METHODS: In this research, we investigated the role of lncRNA MGC27345 in gastric cancer (GC), the expression of MGC27345 in GC was detected by quantitative Real-Time PCR in GC tissue from 235 patients. The correlations between MGC27345 expression and clinicopathological variables and survival were evaluated by the Chi-square test. Kaplan-Meier method (log-rank test), univariate and multivariate Cox regression assays were carried out for the identification of the survival and independent risk factors for GC. RESULTS: MGC27345 expression levels were significantly decreased in GC tissues than in adjacent normal specimens. Lower expression of MGC27345 was found in advanced tumor stages. GC patients with low-expression of MGC27345 had a poorer overall survival compare to those with high-expression of MGC27345. Furthermore, MGC27345 was an independent protective prognosis factor in GC development. CONCLUSIONS: Our data indicated that MGC27345 may have a diagnostic and prognostic value for patients with advanced gastric cancer and assist to improve clinical outcomes for GC patients.
