We therefore performed a meta-analysis to explore the relationship between ADAM8 expression and prognosis in patients with solid tumors. Relevant publications were searched in several widely used databases, and 12 studies (1722 patients) were included in the meta-analysis. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between ADAM8 expression and prognosis. Associations between ADAM8 expression and prognosis were observed for 3-year overall survival (OR = 3.09, 95% CI = 2.33 to 4.10, P < 0.00001) and 5-year overall survival (OR = 4.15, 95% CI = 3.14 to 5.48, P < 0.00001). Similar results were observed when disease free survival (DFS) were analyzed, 3-year DFS (OR = 2.47, 95% CI = 1.66 to 3.69, P < 0.00001) and 5-year DFS (OR = 3.30, 95% CI = 2.29 to 4.74, P < 0.00001). In conclusion, elevated ADAM8 expression is associated with poor prognosis in most solid tumors. ADAM8 is a valuable biomarker for prognosis prediction and a promising therapeutic target in human solid tumors.
