Materials and methods
A cohort of 154 IHC-equivocal (2+) cases of female invasive breast carcinoma patients were recruited between 2012 and February 2014 from sources including referral clinical labs, oncology clinics and Surgical Department of Shifa International Hospital (SIH), Pakistan (including both in hospitalized and referral cases). The paraffin-embedded tissues and surgical specimens immunohistochemically diagnosed as weak HER2 oncoprotein overexpression were included in the study and retrospectively analyzed by dual-probe FISH assay for the clinical assessment of HER2 oncogene and aneusomy 17 in the Cancer Genetics Lab of Quaid-i-Azam University, Islamabad, Pakistan by collaborating with Molecular Biologists and Cytogeneticians. The study protocol was approved by the Institutional Review Board and Ethical Committee (IRB-EC) of SIH and Shifa College of Medicine (SCM) with a reference number (IRB-EC #2069-118-2013).
