- Willingness to provide written informed consent, according to the Good Clinical Practice (GCP) and national/local regulations
- Stage II or III TNBC prior to the start of neoadjuvant treatment: a) Locally assessed stage II or III TNBC according to the primary tumor (T) and regional lymph node (N) staging as per the American Joint Committee on Cancer (AJCC) for breast cancer staging criteria version 8; b) Locally assessed estrogen receptor (ER) and/or progesterone receptor (PR) expression <10% and HER2-negative according to the ASCO-CAP guideline
- The patient has received neoadjuvant treatment with chemotherapy (containing at least anthracyclines and taxanes) and pembrolizumab, with a minimum of two 6-weekly (or four 3-weekly) cycles of pembrolizumab
- The patient underwent breast surgery ≤12 weeks prior to inclusion in the study
- The patient is scheduled to start standard of care adjuvant treatment with capecitabine or olaparib (pending reimbursement), based on non-pCR after neoadjuvant treatment, defined as RCB score >0

- Contra-indications for any of the study drugs
- Other invasive malignancies, except when treated with curative intent without chemotherapy AND more than 5 years ago
- The presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule
