  • Performance Status ECOG <= 1 or KI >= 80%

  • Written informed consent prior to beginning specific protocol procedures, including expected cooperation of the patients for the treatment and follow-up, must be obtained and documented according to the local regulatory requirements

  • The patient must be accessible for treatment and follow-up

  • Patients must qualify for neoadjuvant treatment

  • LVEF > 50%; LVEF within normal limits of each institution measured by echocardiography and normal ECG (within 42 days prior to chemotherapy)

Additional inclusion criteria ADAPT Elderly:

  • ≥ 70 years old
  • Charlson scale ≤ 2
  • HR+/HER2- disease: if RS and sequential testing are available N0-1/RS 12-25/poor response or N0-1/RS ≥26

  • Non-operable breast cancer including inflammatory breast cancer
  • Previous or concurrent treatment with cytotoxic agents for any reason after consultation with the sponsor
  • Concurrent treatment with other experimental drugs. Participation in another clinical trial with any investigational not marketed drug within 30 days prior to study entry (concurrent participation in non-interventional post authorization safety studies not influencing the primary study endpoints is allowed, e.g. WSG PROTROCA for evaluation of primary/secondary G-CSF prophylaxis)

  • Sequential breast cancer
  • Reasons indicating risk of poor compliance
  • Patient not able to consent

Additional Exclusion Criteria ADAPT Elderly:

  • Increases in ALT/AST > CTCAE grade 1
  • Hypokalaemia > CTCAE grade 1
  • Neutropenia > CTCAE grade 1
  • Anaemia > CTCAE grade 1
