SNHG12 and metastatic malignant neoplasm in the lymph nodes: Results of meta-analysis is that SNHG12 high expression is related to low overall survival (HR = 2.72, 95% CI = 1.95–3.8, P < 0.00001), high tumor stage (OR = 3.94, 95% CI = 2.80–5.53, P < 0.00001), high grade (OR = 2.04, 95% CI = 1.18–3.51, P = 0.01), distant metastasis (OR = 2.20, 95% CI = 1.40–3.46, P = 0.0006), tumor size (OR = 2.79, 95% CI = 1.89–4.14, P < 0.00001), and lymph node metastasis (OR = 2.66, 95% CI = 1.65–4.29, P < 0.0001).
