Prognostic value and clinicopathological significance of epithelial cadherin expression in non-small cell lung cancer.

ABSTRACT:

Background

Epithelial cadherin (E-cadherin), a calcium-dependent cell-cell adhesion molecule, as an important adhesion and signaling pathway mediator plays key roles in the maintenance of tissue integrity. However, the available results of E-cadherin expression and its prognostic value on non-small cell lung cancer (NSCLC) remain controversial. Therefore, a meta-analysis of published studies investigating the prognostic value of E-cadherin expression and its association with clinicopathological characteristics with NSCLC was performed.

Methods

A literature search via PubMed, EMBASE, and MEDLINE (Ovid) databases was conducted. Data from eligible studies were extracted. Statistical analysis was performed using STATA 12.0.

Results

A total of 2412 patients from 15 studies were included in the meta-analysis. The results showed that the pooled hazard ratio (HR) for overall survival was 0.55 (95% confidence interval [CI]: 0.44-0.69) by univariate analysis and 0.68 (95% CI: 0.43-1.08) by multivariate analysis. In addition, the results showed a significant association between E-cadherin expression and the presence of lymph node metastasis (odds ratio = 0.37, 95% CI=0.05-0.69, P = 0.001).

Conclusion

Our study showed that positive expression of E-cadherin was associated with a favorable prognosis in patients with NSCLC, and might act as an inhibition factor of metastasis. However, adequately designed prospective studies are required to confirm this finding.

Project description:BackgroundAlthough expression of long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT-1) in tumor tissues has been assessed in several malignancies. However, the association between lncRNA MALAT-1 expression and prognosis or clinicopathological feature remains controversial. Therefore, we conducted a meta-analysis to verify whether lncRNA MALAT-1 expression was associated with prognosis or clinicopathological features in patients with non-small cell lung cancer (NSCLC).MethodsWe searched Embase, PubMed, Web of Science, Cochrane library, The Chinese National Knowledge Infrastructure, and Wanfang databases from inception to March, 1, 2020. The language restrictions were Chinese and English. The published literature on lncRNA MALAT-l expression and prognosis or clinicopathological characteristics of NSCLC patients was statistically analyzed. Combined hazard ratios (HRs), odds ratios (OR), and 95% confidence intervals (95% CIs) were used to evaluate the effects of lncRNA MALAT-l on the prognosis and clinicopathological features of NSCLC.ResultsFifteen studies with 1477 NSCLC patients were enrolled. The results showed that the elevated expression of lncRNA MALAT-l in tumor tissues was associated with shorter overall survival (OS) (HR: 2.20, 95% CI: 1.53-3.16; P = 0.000). Additionally, high lncRNA MALAT-l expression was also significantly associated with gender (OR: 0.69, 95% CI: 0.51-0.93; P = 0.014), tumor size (OR: 1.87, 95% CI:1.13-3.09; P = 0.016), lymph node metastasis (LNM) (OR: 2.87, 95% CI:1.05-7.83, P = 0.04), tumor differentiation (OR: 1.60, 95% CI:1.17-2.20; P = 0.003), and tumor-node-metastasis (TNM) stage (OR: 0.42, 95% CI: 0.25-0.70; P = 0.001). There was no significant relationship between lncRNA MALAT-l expression and other clinicopathological features including age (OR: 1.03, 95% CI: 0.79-1.34; P = 0.830), number of tumors (OR: 1.02, 95% CI: 0.63-1.64; P = 0.943), vascular invasion (OR: 1.23, 95% CI: 0.50-3.05; P = 0.652), and recurrence (OR: 1.98, 95% CI: 0.67-5.85; P = 0.214).ConclusionThe overexpression of lncRNA MALAT-l in NSCLC tissues was correlated with OS, gender, tumor size, LNM, tumor differentiation, and TNM stage. Thus, lncRNA MALAT-l may serve as a prognostic factor for NSCLC.
