    BackgroundSeveral studies have explored the prognostic value of stanniocalcin 2 (STC2) in various cancers, but obtained inconsistent results. Therefore, this meta-analysis was performed to determine the prognostic and clinicopathologic significance of STC2 in various cancers.MethodsEligible studies were identified by searching the online databases PubMed, Embase, Web of Science, and the China National Knowledge Infrastructure up to March 2019. Hazard ratios (HRs) with 95% confidence intervals (CIs) and were calculated to clarify the correlation between STC2 expression and prognosis of different cancers. Odds ratios (ORs) with 95% CI were selected to appraise the correlation between STC2 with clinicopathologic characteristics of patients with cancer.ResultsA total of 16 eligible studies with 4074 patients with cancer were included in our meta-analysis. The results showed that high STC2 expression can predict poor overall survival (OS) for cancer (HR = 1.48, 95% CI: 1.15-1.90, P = .002). Subgroup analysis found that high STC2 expression was associated with worse OS in Asian (HR = 1.85, 95% CI: 1.35-2.55), the reported directly from articles group (HR = 1.39, 95% CI: 1.05-1.84), survival curves group (HR = 1.93, 95% CI: 1.36-2.74), and gastric cancer (HR = 1.43, 95% CI: 1.04-1.95). Furthermore, high STC2 expression was significantly related to advanced T stage (OR = 1.83, 95% CI: 1.17-2.86, P = .008), lymph node metastasis (OR = 2.29, 95% CI: 1.51-3.45, P < .001), lymphatic invasion (OR = 2.15, 95% CI: 1.53-3.02, P < .001), venous invasion (OR = 1.97, 95% CI: 1.30-2.99, P = .001), and more advanced clinical stage (OR = 2.36, 95% CI: 1.74-3.19, P < .001) CONCLUSION:: Elevated expression of STC2 suggested a poor prognosis in patients with cancer and may serve as a new tumor marker to monitor cancer development and progression.
