This study aims to analyze the expression and clinical significance of Platelet endothelial cell adhesion molecule 1 (PECAM-1) in breast cancer and the correlation between PECAM-1 and immune infiltrations. We performed a bioinformatic analysis of the prognostic value and immune infiltration correlation of PECAM-1 in breast cancer. The results showed that there were significant differences in PECAM-1 expression levels between breast invasive carcinoma tissues and adjacent normal tissues. The high expression of PECAM-1 was significantly related to favorable overall survival, progression-free survival and distant metastasis free survival in patients with breast cancer. There were significantly positive correlations with the levels of infiltrated B cell, CD4+T cells, CD8+ T cells, neutrophils, macrophages, and dendritic cells in breast cancer. In summary, the expression of PECAM-1 can serves as a prognostic biomarker in breast invasive carcinoma and is correlated with immune infiltrates.
