Résumé : Neoadjuvant chemo-immunotherapy for high-risk triple-negative breast cancer (TNBC) has been shown to reduce the risk of recurrence and improve survival. However, the prognosis for patients with metastatic TNBC remains poor, especially for those with an early recurrence, who represent an urgent unmet need. Defining the most common timing of recurrences after chemo-immunotherapy is crucial for shaping the design of future clinical trials.
