Molecular and genomic pathology is an essential cornerstone of diagnosis in breast disease, to such an extent that genetic information is already included in therapeutic decision-making. There are now various commercial platforms available in the clinic, generally with little or no agreement in the genes included, in their technical basis, in the definition of risk groups, in the information they provide, in their indications or in the protocols required to use them. Objective To evaluate the use and knowledge of these platforms. Material and methods An eleven-question survey was conducted targeting breast units accredited by the SESPM in Spain at that time. Results 26 units out of the 36 surveyed responded and data was obtained that can guide the use of the platforms and serve as a starting point towards gaining a deeper knowledge of them. Conclusions The indications approved by the Autonomous Regions need to be re-evaluated. There is insufficient evidence to base decisions about the axilla on the platforms. MammaPrint® is the only platform with level of evidence 1a for N1–3 patients. It also identifies a subgroup of patients who may not require hormonal treatment.
