Downregulated E-Cadherin Expression Indicates Worse Prognosis in Asian Patients with Colorectal Cancer: Evidence from Meta-Analysis
<div><p>Background</p><p>Epithelial-mesenchymal transition (EMT) plays a crucial role in the progression and aggressiveness of colorectal carcinoma. E-cadherin is the best-characterized molecular marker of EMT, but its prognostic significance for patients with CRC remains inconclusive.</p><p>Methodology</p><p>Eligible studies were searched from the PubMed, Embase and Web of Science databases. Correlation between E-cadherin expression and clinicopathological features and prognosis was analyzed. Subgroup analysis was also performed according to study location, number of patients, quality score of studies and cut-off value.</p><p>Principal Findings</p><p>A total of 27 studies comprising 4244 cases met the inclusion criteria. Meta-analysis suggested that downregulated E-cadherin expression had an unfavorable impact on overall survival (OS) of CRC (nβ=β2730 in 14 studies; HRβ=β2.27, 95%CI: 1.63β3.17; Zβ=β4.83; Pβ=β0.000). Subgroup analysis indicated that low E-cadherin expression was significantly associated with worse OS in Asian patients (nβ=β1054 in 9 studies; HRβ=β2.86, 95%CI: 2.13β3.7, Zβ=β7.11; Pβ=β0.000) but not in European patients (nβ=β1552 in 4 studies; HRβ=β1.14, 95%CI: 0.95β1.35, Zβ=β1.39; Pβ=β0.165). In addition, reduced E-cadherin expression indicated an unfavorable OS only when the cut off value of low E-cadherin expression was >50% (nβ=β512 in 4 studies; HRβ=β2.08, 95%CI 1.45β2.94, Zβ=β4.05; Pβ=β0.000). Downregulated E-cadherin expression was greatly related with differentiation grade, Dukes' stages, lymphnode status and metastasis. The pooled OR was 0.36(95%CI: 0.19β0.7, Zβ=β3.03, Pβ=β0.002), 0.34(95%CI: 0.21β0.55, Zβ=β6.61, Pβ=β0.000), 0.49(95%CI: 0.32β0.74, Zβ=β3.02, Pβ=β0.002) and 0.45(95%CI: 0.22β0.91, Zβ=β3.43, Pβ=β0.001), respectively.</p><p>Conclusions</p><p>This study showed that low or absent E-cadherin expression detected by immunohistochemistry served as a valuable prognostic factor of CRC. However, downregulated E-cadherin expression seemed to be associated with worse prognosis in Asian CRC patients but not in European CRC patients. Additionally, this meta-analysis suggested that the negative threshold of E-cadherin should be >50% when we detected its expression in the immunohistochemistry stain.</p></div
