Re-Examination of Tumor Material and Re-Evaluation of Patient Data From Patients Treated With Neo-adjuvant Therapy
Evaluation of the MammaTyper Kit, Ref 90020/90021 Performed on Clinical Material Obtained From Patients With Early Breast Cancer: Re-Examination of Tumor Material and Re-Evaluation of Patient Data From Patients Treated With Neo-adjuvant Therapy
This is a prospective examination of ribonucleic acid (RNA) extracted from tumor material of breast cancer patients treated with a neo-adjuvant therapy. The RNA will be analysed for expression of estrogen receptor (ER 1), progesterone receptor (PgR), HER2 and Ki-67 with MammaTyper™.
According to the determined values for the individual parameters at least 4 subtypes can be distinguished to date
- Luminal A-type
- Luminal B-type
- HER2-type
- Triple-negative-type As non-clinical endpoint, the agreement of new subtyping with Immunohistochemical methods will be evaluated.
As clinical objective, the 5 year Distant metastasis free survival (DMFS) and Overall survival (OS) will be reevaluated according to the new subtyping.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
MammaTyper™
MammaTyper™ will be used to assess tumor material of patients treated with neo-adjuvant therapy.
|
MammaTyper™ is an in vitro molecular diagnostic test for the quantitative detection of the biomarkers estrogen receptor (ESR1), progesterone receptor ( PgR), Human epidermal growth factor receptor 2 (HER2) and proliferation antigen Ki-67 on the basis of the values of the messenger ribonucleic acid (mRNA).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Agreement of new subtyping assessed as rate of patients in MammaTyper-subtype groups compared to rate of patients in subtype groups according to immunohistochemical analysis according to St. Gallen Guideline 2013
Time Frame: Baseline
|
For each MammaTyper and immunohistochemical based subtype categorization, percent agreement, positive and negative percent agreement as well as kappa-statistics are calculated.
|
Baseline
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess difference of 5 year OS of breast cancer subgroup Luminal A vs. combined subgroup (Luminal B (HER2 positive / HER2 negative), HER2 positive, triple negative), based on subtyping with MammaTyper™
Time Frame: 5 years from the date of patient registration
|
Assessed as rate of patients in subgroup Luminal A with 5 year OS vs.
rate of patients in combined subgroups with 5 year OS based on MammaTyper subtyping
|
5 years from the date of patient registration
|
Estimation of difference in prediction of pathologic complete remission for MammaTyperTM Ki-67 vs. local Ki-67 visual scoring assessment for Luminal tumors, whereby a positive difference is expected
Time Frame: Baseline
|
Assessed as rate of patients with complete response and Ki-67 determination according to MammaTyper and visual scoring assessment
|
Baseline
|
ESR1 mRNA is predictive for 5 year OS with low expression of ESR1 mRNA being associated with adverse outcome (rate of patients with 5 year OS and high or low expression of ESR1 mRNA)
Time Frame: 5 years from the date of patient registration
|
Assessed as rate of patients with 5 year OS and high or low expression of ESR1 mRNA
|
5 years from the date of patient registration
