Summary
Brief summary (as posted)
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.

Primary outcomes (1)
- measure
- 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
- timeFrame
- Baseline
- description
- For each MammaTyper and immunohistochemical based subtype categorization, percent agreement, positive and negative percent agreement as well as kappa-statistics are calculated.
Secondary outcomes (3)
- measure
- 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™
