  • The follow-up time was not less than 3 months after the initiation of palbociclib in combination with endocrine therapy (retrospective part);
  • Age ≥ 18 years, female (prospective part);
  • Histologically or cytologically confirmed recurrent or metastatic HR+/HER2- breast cancer, if there is metastatic pathology, the histological pathology of metastases should prevail (prospective part);
