This study of patients with triple-negative (TNBC) or human epidermal growth factor receptor 2 (HER2)-positive (HER2+) breast cancer who underwent neoadjuvant therapy aims to assess whether occult residual disease (ORD) can be identified in deeper sections of tumour beds and lymph nodes in cases originally reported as pCR and whether ORD is associated with worse outcomes.</p><p><strong>Methods and results: </strong>In 84 cases of pCR (2009-17) at our institution, deeper-level recuts were assessed for ORD.
