ObjectiveTo investigate the expression of epidermal growth factor receptor (EGFR) in triple-negative breast cancer (TNBC) and its relation with clinicopathologic features. MethodsA computer search of PubMed, Web of Science, CNKI, Wanfang Data, and VIP databases were conducted to select clinical studies on EGFR expression in the TNBC according to the inclusion and exclusion criteria, and the search period was from database establishment to January 2022. Two researchers independently screened the literature, extracted the data, and evaluated the quality of the literature before conducting meta-analysis using RevMan 5.4 software. ResultsA total of 28 studies including 7 956 patients were included. The results of meta-analysis showed that the positive rate of EGFR expression in the TNBC patients was higher than that in the non-TNBC patients [OR=5.16, 95%CI (4.04, 6.58), P<0.000 01], and the proportions of patients with axillary lymph node metastasis [OR=3.11, 95%CI (1.56, 6.19), P=0.001] and with tumor diameter >2 cm [OR=2.09, 95%CI (1.18, 3.72), P=0.01] in the patients with EGFR positive were higher than those the patients with EGFR negative, no correlation was found that the proportion of patients with histological WHO classification 3 between the patients with EGFR positive expression and EGFR negative expression (P=0.07). ConclusionFrom the results of this meta-analysis, EGFR expression might be associated with the occurrence, development, and metastasis of patients with TNBC.
