						  Background: Evaluation HER2 (human epidermal growth factor receptor 2) status is considered as a standard
  practice in breast cancer clinical management. There are different methods for evaluation HER2 status, but currently
  the routine method for assessment of HER2 status is Immunohistochemistry (IHC) .The aim of the this study was to
  compare the results obtained by IHC and Quantitative Real Time PCR methods in determination of HER2 status to
  specify whether QRT- PCR can use as supplementary method in breast cancer or not.
Methods: In this regard, 48 fresh tissues from patients with breast tumor were studied. IHC, qRT- PCR technique
  was done in every speciman. IHC was done with DAKO HercepTest and QRT- PCR method was performed with
  TaqMan probes and primers in lightcyclerTMsystem (Corbett Real Time Thermal cycler).
