- Abstract
Background: It has been shown that caveolin-1 plays a potential role as a diagnostic and prognostic biomarker in various cancer types. The aim of the present study was to clarify whether caveolin-1 expressed in the breast cancer stroma could be a prognostic factor for breast cancer patients. Methods: We searched the PubMed, ScienceDirect and Web of Science databases for published literature investigating associations between stromal caveolin-1 expression and survival outcome in breast cancer patients. With respect to survival outcomes, the pooled hazard ratios (HRs) of caveolin-1 and the 95% confidence intervals (CI) were calculated. Results: Our meta-analysis identified a total of 10 studies involving 2072 cases. Further investigation demonstrated that a lack of caveolin-1 expression in the breast cancer stroma is a hazard for overall survival (OS) (HR = 2.33, 95% CI: 1.57-3.46) and disease-free/progression-free survival (DFS/PFS) (HR = 3.05, 95% CI: 2.26-4.12) in breast cancer patients. Moreover, lack of caveolin-1 expression in the cancer-associated fibroblasts was a significant predictor of DFS/PFS (HR = 2.79, 95% CI: 1.75-4.46). Conclusion: Our results indicated that lack of expression of caveolin-1 in the breast cancer stroma is associated with a poor prognosis.
