Abstract: | Background and Objectives: Mesothelin, identified as a tumor-associated biomarker, is more often overexpressed in triple receptor-negative breast cancer (TNBC) than in common luminal breast tumor subtype or normal tissues. The objective of this systematic review is to determine the association between the expressions of mesothelin with survival outcomes in patients with TNBC. Methods We searched the following electronic databases: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, PubMed, and Web of Science with no time or language restriction till May 19, 2016. Any prospective or retrospective longitudinal studies that investigate the prognosis of TNBC with mesothelin baseline measurement were selected. Two reviewers independently assessed every article for inclusion, extracted data, and assessed the methodological quality of every eligible trial. Pooled measures of associations were summarized with meta-analyses. Results and conclusions Among the 592 patients with TNBC included in the four eligible studies, 269 patients (45.4%) demonstrated mesothelin expression. For the primary outcome OS, we found the trend toward decreased survival for patients with mesothelin-positive TNBC than those without mesothelin expression. We also found that for long-term OS, the association was statistically significant (OR = 0.46; 95% CI= 0.30 to 0.73; P< 0.001). For the secondary outcomes, we found that mesothelin expression in patients with TNBC was associated with lower DFS and higher overall mortality than those without mesothelin expression. Despite the limitations of sample size, this present study shows a significant association between mesothelin expressions and survival outcomes in patients with TNBC. Patients with mesothelin-positive TNBC could benefit from mesothelin-targeted immunotherapies recently in the development. |
