The study aims to compare the time-to-treatment failure of a palbociclib + endocrine therapy against a pre-chosen mono-chemotherapy in a real world setting. Time-to-treatment failure (TTF) is defined as time from randomization to discontinuation of treatment due to disease progression, treatment toxicity, patient’s preference, or death.Furthermore the study will compare patient´s quality of life extensively.

2. Female or male patients.
3. Age = 18 years old.
4. Metastatic invasive hormone receptor positive and HER2 negative breast cancer (histologically confirmed).
5. Patients who in the opinion of the treating physician are candidates suitable for randomization for mono-chemotherapy treatment, that has either an approved label in Europe and/or is supported by guidelines for the treatment of first-line advanced BC, which are based on evidence on safety and efficacy in this setting.
6. Symptomatic or asymptomatic metastatic breast cancer.
7. Resolution of all acute toxic effects of prior anti-cancer therapy or surgical procedures to NCI CTCAE version 4.0 grade = 1 (except alopecia or other toxicities not considered a safety risk for the patient at investigator's discretion).
8. Life-expectancy > 6 months.
9. For female patients: The patients need to be either A) of non-childbearing potential (documented postmenopausal or post hysterectomy) B) childbearing potential with negative serum or urinary pregnancy test (in this case patients need to use highly effective non-hormonal contraceptive methods).
