3 Disease-Free and Overall Survival in Metastatic Breast Cancer AGO e. V. in der DGGG e.v. sowie in der DKG e.v. Guidelines Breast Version Oxford / AGO LoE / GR An increase in survival over time in MBC has 2a been shown in some retrospective analyses However, patients with MBC today have received 2a more adjuvant treatment and have therefore considered more drug resistant Multiple lines of sequential therapy are 1b beneficial (at least same efficacy, less toxicity) Especially targeted drugs in combination with 1b chemotherapy can induce substantial survival benefits

4 Treatment of Metastatic Breast Cancer Predictive Factors AGO e. V. in der DGGG e.v. sowie in der DKG e.v. Guidelines Breast Version Therapy Factor Oxford / AGO LoE / GR Endocrine therapy ER / PR (primary tumor, metastasis) 1a A ++ previous response 2b B ++ Chemotherapy previous response 1b A ++ Anti-HER2-drugs HER2 (primary tumor, better metastasis) 1a A ++ Bone modifying drugs bone metastasis 1a A ++ Any therapy CTC monitoring 1b A +* (other potentially biological factors see chapter Predictive factors ) *within clinical trials

7 Study Design N=800 pts. with HR+/HER2- breast cancer no pcr and CPS-EG score 3 : Palbociclib 125 mg once daily p.o. d1-21, q28d for 13 cycles Neoadjuvant Chemotherapy Surgery +/- Radiotherapy R Placebo d1-21, q28d for 13 cycles All patients will receive concomitantly endocrine therapy according to local standards

8 Cytotoxic Therapy Goals AGO e. V. in der DGGG e.v. sowie in der DKG e.v. Guidelines Breast Version Oxford LoE: 1b GR: A AGO: ++ Mono-Chemotherapy: Favourable therapeutic index Indicated in case of Slow, not life-threatening progression Insensitive to or progression during endocrine therapy Poly-Chemotherapy: Unfavourable therapeutic index Indicated to achieve rapid remission in the case of Extensive symptoms Imminent life-threatening metastases Survival benefit in comparison to sequential singleagent therapies with the same compounds not proven Therapeutic index evaluates overall efficacy, toxicity and impact on quality of life

9 Chemotherapy for MBC General Considerations: Drug Selection AGO e. V. in der DGGG e.v. sowie in der DKG e.v. Guidelines Breast Version AGO: ++ The choice of cytotoxic drugs to be used depends on: ER / PR, HER2; combination with biologicals Previous treatments (and their toxicities) Disease-free interval after end of adjuvant treatment Aggressiveness of disease and localization of metastases Estimated life expectancy Co-morbidities (including organ dysfunctions) Patients preference and expectations

10 ESMO Guidelines ABC: Update on HER-2-negative Advanced Breast Cancer Sequential monotherapy is the preferred choice for MBC. Combination CT should be reserved for patients with rapid clinical progression, lifethreatening visceral metastases, or need for rapid symptom and/or disease control (LoE 1A) Although taxanes can be used as first-line therapy, they have not shown superior benefit to anthracyclines in a meta-analysis carried out in a mostly taxane-naive, anthracycline-pre-treated patient population HELIOS Klinikum Berlin-Buch
