Intertumoral heterogeneity of bifocal breast cancer: a morphological and molecular study. (PubMed, Breast Cancer Res Treat)
In bifocal BC, intertumoral heterogeneity on the morphological, immunohistochemical and molecular level is common, with discordant intrinsic subtype in up to 25% between individual foci, with about 8% clinically relevant discordances.

SABCS 2023: Study shows that locally-performed MammaTyper®test provides accurate prediction of low RS score for breast cancer prognosis (Shuwen Biotech Press Release)
"A seminal study presented at the San Antonio Breast Cancer Symposium (SABCS) this week has shown that the validated, locally performed, RNA-based MammaTyper® test provides progesterone receptor (PGR) expression determination that could predict low recurrence risk score under OncoType DX and independently identify breast tumours that are unlikely to be chemotherapy sensitive. This could obviate further testing with the multigene signature prognostic assay for up to 70% of patients."

Dynamics and prognostic value of subtype specific TROP2 expression in matched pair samples of primary (PBC) and metastatic breast cancer (MBC) tissues (SABCS 2023)
In this selected matched pair, metastatic cohort, TROP2 mRNA in primary tumors is strongly associated with luminal type of breast cancer expressing higher levels of PGR mRNA, while no such correlation was found in matched metastatic tissues. Moreover, TROP2 is significantly downregulated in metastatic lesions. As TROP2 is expressed in luminal tumors, it may serve as a valuable target for luminal tumors of higher progression risk.

ERBB2 mRNA expression to distinguish HER2-low/neg breast cancer prognosis. (ASCO 2023)
Background: Antibody-drug conjugates such as Trastuzumab deruxtecan significantly improved progression-free and overall survival for the HER2 low expression (HER2-low) breast cancer (BC) patients, pushing the research field of HER2-low to a new climax... Compared with IHC/FISH, MammaTyper qRT-PCR assay may actually reflect the prognosis of HER2-neg/low, which is expected to become a diagnostic beacon for HER2-low target drugs.

Integrative cross-platform characterisation of mammographic screen-detected breast cancer (AACR 2023)
Targeted sequencing with Oncomine Comprehensive Assay V3 did not reveal particular mutational patterns between the two Luminal A groups. Nevertheless, radiomic analysis of mammographic images of the cancer, as well as single cell phenotyping of the tumor microenvironment with protein multiplexing will be incorporated to further characterise elements that are phenotypically different, and potentially identify mechanistic drivers contributing to late recurrence in Luminal A cancers.

Comparison of ER, PR, HER2 and Ki67 expression by MammaTyper® RT-qPCR and immunohistochemistry (IHC) on needle core biopsies of breast cancer (EBCC 2022)
MKI67 by MammaTyper® exhibited a higher concordance with the digital Ki67 image analysis. This suggests that MammaTyper® test on needle biopsies represents a reliable, efficient and reproducible alternative for breast cancer 4- marker detection and molecular subtyping.

ERBB2 mRNA expression in HER2-low breast cancer (EBCC 2022)
Background: Trastuzumab deruxtecan significantly increased progression-free and overall survival than the physician’s choice of chemotherapy for the HER2-low breast cancer (BC) patients, which opened a new chapter in the treatment of HER2-low BC...High mRNA expression of ERBB2 partially explained the response to T-DM1 in HER2 positive breast cancer, which brings up the possibility of precise detection of mRNA expression of ERBB2 to define HER2-low cohort and its guidance on drug administration... Compared with IHC/FISH, MammaTyper® qRT-PCR assay may be a promising alternative for actual detection of ERBB2 expression and define HER2-low breast cancer.

Looking for more reliable biomarkers in breast cancer: Comparison between routine methods and RT-qPCR. (PubMed, PLoS One)
Determination of the breast cancer biomarkers ER, PR, HER2 and Ki67 at the mRNA level shows high degree of correlation with IHC and compares well with correlations between original with subsequent independent manual or semi-automated IHC assessments. The use of methods with wider dynamic range and higher reproducibility such as RT-qPCR may offer more precise assessment of endocrine responsiveness, improve Ki67 standardization and help resolve HER2 cases that remain equivocal or ambiguous by IHC/FISH. In summary, our findings seem to configure RT-qPCR as a complementary method to be used in cases of either equivocal results or presenting, at the traditional determination assays, biomarkers expressions close to the cut-off values.

Luminal A versus B breast cancer: MammaTyper® mRNA versus immunohistochemical subtyping with emphasis on standardised Ki67-Labelling or Mitotic Activity Index based proliferation assessment. (PubMed, Histopathology)
"High agreement rates between mRNA and IHC based intrinsic subtyping of luminal HER2 negative BC can be achieved. However, concordance between IHC and MammaTyper based luminal subtypes depends on proliferation assessment method and was highest using the mitotic activity index. Further comparative clinical studies have to address which method is to be preferred, including analysis of cost-effectiveness."

Comparison of MammaTyper® RT-qPCR based subtyping with simulated breast cancer prognostic signatures (SABCS 2019)
"Low cost local RT-qPCR measurements by MammaTyper® show a high agreement with the scores generated by our Oncotype DX-trained scores. The academic and well validated 95-gene signature agrees well with MammaTyper® MKI67 single gene measurement. Therefore, the locally performed MammaTyper® test may serve as cost effective surrogate for complex prognostic signatures or at least enables a pre-screening for molecularly “obviously” low risk samples."

Prediction of pathological complete response (pCR) upon neoadjuvant chemotherapy by MammaTyper® pCR score (SABCS 2019)
"The MammaTyper® pCR score may serve as a standardized tool to predict response to NACT based on a pre-treatment biopsy. For patients with inoperable Luminal tumors and low predicted probability of pCR, neo-adjuvant aromatase inhibitor alone or combined with the new generation of TKIs such as CDK4/6 inhibitors or Pi3KCa/mTOR inhibitors may be an alternative for downstaging of tumors."
