Comprehensive molecular subtyping of breast cancer patients
- Precise determination of HER2, ER, PR and Ki-67 in one assay
- Definitive breast cancer subtyping for confident treatment decisions
- Easy-to-use, quantitative and observer-independent testing
- Fast turnaround time and results within the same day
- CE-marked IVD RT-qPCR assay for most commonly available cyclers
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 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.
MammaTyper® is an easy-to-use test for any pathology laboratory, delivering precise results within 6 hours.
