Inclusion Criteria:
* 18 years of age and above;
* Women of any menstrual status;
* Histologically confirmed recurrent or metastatic breast cancer, including patients initially diagnosed as stage IV or locally advanced inoperable;

* Patients have at least 3 more fully documented medical records at the enrolled centre, including at least 1 inpatient record.
Exclusion Criteria:

Primary outcome measure(s)
Progression Free Survival — From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months Progression-free survival estimated using Kaplan-Meier methods is defined as the time from the date of informed consent to the earlier of death or disease progression. Patients alive without disease progression are censored at the date of last disease evaluation. Progressive disease (PD) based on RECIST 1.1 is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Equivocal progression of non-target lesions also qualifies as PD.
