SNHG1 and metastatic malignant neoplasm in the lymph nodes: In 2019, a meta-analysis reviewed the prognostic value of lnc-SNHG1 expression in eight solid malignant tumors and indicated that the expression of lnc-SNHG1 significantly correlated with reduced OS (HR = 1.917; 95% CI, 1.58–2.31) (P < 0.001), TNM stage (OR = 3.99; 95% CI, 2.48–6.43), and lymph node metastasis (OR = 3.12; 95% CI, 1.95–4.98).
