Long noncoding RNAs (lncRNAs) play vital roles in development and progression of various cancers. To investigate the relationship between three tag single-nucleotide polymorphisms (SNPs) (rs13252298, rs1016343, and rs1456315) in lncRNA prostate cancer-associated noncoding RNA 1 (PRNCR1) and lung cancer (LC) risk, we conducted this study. First, we performed a case–control study, including 576 LC patients and 612 cancer-free controls. Second, a meta-analysis was used to evaluate the association of selected SNPs with risk of overall cancer. We found that rs13252298 and rs1456315 were strongly correlated with risk of LC, nonsmall cell lung cancer (NSCLC), and lung adenocarcinoma. For rs13252298, individuals carrying GG genotype had increased risks of LC compared with those carrying AA genotype (adjusted odds ratio [OR] = 1.565, 95% CI = 1.091–2.245, p = 0.015). A significant result was also found in recessive model with adjusted OR of 1.719. Individuals with GG genotype of rs1456315 were at increased risks of LC compared with those carrying AA genotype. Similar results were found in NSCLC patients. Meta-analysis showed that rs1016343 and rs13252298 were associated with overall cancer. But for rs1016343, no significant association was observed in Asians. In conclusion, rs13252298 and rs1456315 in PRNCR1 may be genetic susceptibility factors for LC in Chinese population. These results need to be confirmed by further studies.
