[Articles] Metronomic capecitabine as extended adjuvant chemotherapy for early triple-negative breast cancer (SYSUCC-001): updated 10-year outcomes and post-hoc exploratory biomarker analysis from a randomised, phase 3 trial

In this exploratory, long-term analysis, extended adjuvant metronomic capecitabine provided durable disease-free survival benefit in early triple-negative breast cancer, although the findings should be interpreted with caution given the post-hoc nature of the analysis. Patients with FOXC1-high tumours showed a survival advantage with capecitabine versus observation; if this finding is validated, FOXC1-driven patient selection might be useful to optimise therapeutic responses.
