The recently published ASCO1 guidelines concerning the use of biomarkers to guide decisions on adjuvant systemic therapy for early breast cancer patients includes for the first time second generation prognostic gene signatures in the panel of eligible analyses (level IB evidence).
This presentation will focus on the application of PAM50 in a subset of Danish breast cancer patients, identifying patients with a very low 10-year risk of distant recurrence. The test allows for considerations of omitting chemotherapy in these patients.
