Abstract:
Metastatic breast cancer (MBC) management is based on systemic treatment (ST), while the local therapy role remains controversial. We present the case of a 36-year-old woman with a diagnosis of hormone receptor-positive and human epidermal growth factor receptor type 2-positive breast cancer and isolated sternal metastasis, who received neoadjuvant ST with complete remission and later primary tumour surgery. Oligometastatic patients are a subgroup of MBC that can benefit from aggressive local therapies, even with curative intent.
