To explore the association between HOTAIR rs4759314 and cancer risk. A comprehensive online search was conducted using PubMed, EMBASE, and CNKI databases to identify relevant studies. The case-control studies related to HOTAIR rs4759314 polymorphism and cancer risk were selected according to the inclusion and exclusion criteria. The retrieval time was until November 2015. After extracting the basic data information and performing an evaluation of the quality of the literature, the meta-analysis was performed using STATA 12.0 software, by calculating the odds ratio (OD) and 95% confidence interval (95% CI), and further subgroup analysis, literature publication bias testing, and sensitivity analysis. The studies included a total of 5025 patients with cancer and 5657 controls. The results found no significant association between the HOTAIR rs4759314 polymorphism and cancer risk in a Chinese population (G vs A, OR=1.06, 95% CI :0.87-1.30 ; GG/GA vs AA, OR=1.07, 95% CI: 0.87-1.32; GG vs GA/AA, OR=0.75, 95% CI:0.39-1.43; GA vs AA, OR=1.08, 95% CI: 0.88-1.33; GG vs AA, OR=0.76, 95% CI:0.39-1.45) (all p<0.05). However, A allelic gene was associated with lower risk of gastric cancer, while G allelic gene may act as a genetic susceptibility factor for gastric cancer in Chinese population. No significant association was noted between the HOTAIR rs4759314 polymorphism and cancer risk in a Chinese population.
