Notes:
SLC50A1 high expression: > median primary breast cancer expression.
Female patients with primary, unilateral breast cancer were included.
Fisher’s exact test.
According to Bloom and Richardson and modified by Elston and Ellis.1
According to UICC TNM classification in breast cancer.2
IRS according to Remmele and Stegner.3
Overexpression of the ERBB2 gene (Her-2/neu) was diagnosed to the threshold of the DAKO score system based on the IHC assay. Uncertain cases were additionally validated by the FISH assay.
Abbreviations: FISH, fluorescence in situ hybridization; IHC, immunohistochemistry; IRS, immunoreactive score.
