This agrees with other published data where the FGFR2 expression was higher in breast tumours that are ER+PR+ and ER+PR− compared to ER−PR− tumours [41,45], although FGFR2 has been found to be high in TNBC as well [39], which can also be seen in our study. This evidence concerns the gene FGFR2 and breast neoplasm.
