Recently, the lncRNA small nucleolar RNA host gene 1 (SNHG1) was found to be high-expressed and functioned as an oncogene in various cancers, such as nonsmall-cell lung cancer,[14] gastric cancer,[15] and colorectal cancer.[16] Previous studies have revealed that upregulated SNHG1 expression predicted poor prognosis for some cancers.[17–19] Meanwhile, SNHG1 express level was correlated with LNM, distant metastasis (DM) and TNM stage in various cancers.[20,21] To date, no meta-analysis has been performed to examine the relationship between SNHG1 and the relevant clinical outcomes. The gene discussed is SNHG1; the disease is lung cancer.
