Summary: This study is to find out that if HER-2 positive and HR positive patients could benefit from trastuzumab and pertuzumab combined with palbociclib and endocrine therapy.

Detailed description: This study is a single-arm, open-label, multicenter, phase II clinical study. Subjects were eligible for screening and entered the trial period after enrollment and received treatment with palbociclib（125mg/day), trastuzumab(8 mg→6mg/every 3 week), pertuzumab(840 mg→420mg/every 3 week), combined with endocrine therapy until disease progression, or intolerable toxicity, or withdrawal of informed consent, or discontinuation of medication at the investigator 's discretion. On-study imaging assessments were performed according to RECIST 1.1 criteria and the site assessment was final.
