Concordance between HER-2 status determined by qPCR in Fine Needle Aspiration Cytology (FNAC) samples compared with IHC and FISH in Core Needle Biopsy (CNB) or surgical specimens in breast cancer patients

In conclusion, our study demonstrates that qPCR performed using fine-needle aspiration samples from a primary tumour is a reliable and fast method to determine HER2/neu status in patients with early breast cancer.
