Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited treatment options and historically poor outcomes. Prior to the emergence of antibody–drug conjugates (ADCs), palliative sequential single-agent chemotherapy was the mainstay of treatment for metastatic TNBC (mTNBC), offering limited response and survival. In an interview with MIMS Oncology, Dr Rodrigo Sánchez-Bayona from the Universitary Hospital 12 de Octubre, Madrid, Spain, discussed how Trop-2–targeted ADCs have changed the treatment landscape of mTNBC and predicted their future role in the changing treatment paradigm. He highlighted data on sacituzumab govitecan (SG), an ADC that has demonstrated efficacy regardless of Trop-2 expression status or presence of biomarkers while maintaining quality of life (QoL), and shared a patient case with rapidly progressing mTNBC effectively treated with SG.
