Abstract:
CD47 functions as a dominant anti-engulfment signal on tumour cells and is overexpressed in various malignant tumours. However, the expression and functional significance of CD47 in triple-negative breast cancer (TNBC) is not completely understood. In the present study, CD47 was demonstrated to be overexpressed in TNBC solid tumours. Moreover, increased CD47 expression was significantly associated with an advanced tumour-node-metastasis stage, lymph node involvement and recurrence. Moreover, CD47 was an unfavourable and independent prognostic factor for 5-year disease-free survival in patients with TNBC. In addition, the expression of CD47 was associated with several markers of epithelial-mesenchymal transition (EMT). The present study was the first to demonstrate an association between increased expression of CD47 with EMT and poor prognosis of TNBC. Thus, CD47 may be a potential prognostic biomarker and therapeutic target for TNBC.
