Compliance with ethical standards
:
: Author M.B. Jensen declares institutional research support from NanoString and institutional research support from Oncology Venture. All other authors declare that they have no conflicts of interest.
: The scientific committee of the NBCA and the DBCG Board, and the RKKP approved this study. All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.
: The Danish Breast Cancer Clinical Quality Database is approved by the Danish Health Authority (Sundhedsdatastyrelsen). The DBCG holds permission to collect, store, and process data on all patients diagnosed with invasive breast cancer in Denmark, and the programme is exempt from patient consent to data collection. According to the Dutch law, all breast cancer patients are included in the NBCA database, unless the patient has objected to be registered. Therefore, informed consent is not applicable for the current register-based research that does not involve contact with study participants or biological samples.
: Funding sources had no role in the study design, data collection, analysis, interpretation of the data, writing of the manuscript, or the decision to publish.
