MammaTyper®

MammaTyper® precisely quantifies expression of HER2, ER, PR and Ki-67 mRNA

MammaTyper® is a molecular diagnostic test for quantitative determination of the four key biomarkers used in the subtyping of breast cancer.

Human epidermal growth factor receptor 2 (HER2), estrogen receptor (ER), progesterone receptor (PR) and the marker of proliferation Ki-67 are key biomarkers in the evaluation of breast cancer tumours.

The combination of biomarker results allows the assessment of the different St. Gallen Breast Cancer subtypes which are key parameters for treatment decisions.

Definition of Breast Cancer Surrogate Subtypes
(St Gallen 2013)

Breast Cancer Subtypes ER PR HER2 Ki-67
Luminal A-like Pos Pos Neg Neg
Luminal B-like (HER2 negative) Pos Pos/Neg* Neg Pos/Neg*
Luminal B-like (HER2 positive) Pos Pos/Neg Pos Pos/Neg
HER2 positive (non-luminal) Neg Neg Pos Pos/Neg
Triple negative (ductal) Neg Neg Neg Pos/Neg

*with the exception of the combination PR pos and Ki-67 neg = Luminal A-like

MammaTyper® is designed to meet the need for standardized, quantitative and fast molecular subtyping enabling confident treatment decisions.
