Palbociclib combined with Fulvestrant
Fulvestrant Injectable Product
Fulvestrant is in the form of a prefilled syringe containing 5 ml of an injection solution of 250 mg of fulvestrant for intramuscular injection. The recommended dose is once every 28 days, once at a dose of 500 mg, and on the 15th day after the initial injection, a loading dose of fulvestrant 500 mg is added.
Palbociclib
Palbociclib is in the form of oral capsules, which are divided into three specifications: 75 mg, 100 mg and 125 mg. The recommended dose is 125 mg once daily for 21 days, followed by 7 days (3/1 dosage regimen), 28 Day is a treatment cycle.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
(2b) Meet any of the following criteria: a) previous endocrine-assisted treatment completed 2 years and above, and recurrence and metastasis of evidence of imaging progression during treatment, and no subsequent endocrine therapy after progression; b) completion of adjuvant endocrine After treatment, recurrence and metastasis of evidence of imaging progression occurred within 1 year, and no subsequent endocrine therapy was received after progression; c) recurrence and metastasis occurred after more than 1 year after completion of adjuvant endocrine therapy, and then received anti-estrogen drugs or aromatase inhibitors as evidence of disease progression after first-line endocrine therapy and evidence of imaging progression, patients may not have more than 1 line of endocrine therapy for recurrent metastatic disease; d) primary metastatic disease, and subsequent anti-acceptance Estrogen drugs or aromatase inhibitors as a first-line metastatic disease after endocrine therapy disease progression and evidence of imaging progression, patients can not receive more than 1 line of endocrine therapy for metastatic disease.
3\) Postmenopausal or premenopausal/perimmenopausal women can be enrolled. In postmenopausal state, defined as meeting at least one of the following criteria: previous bilateral ovarian surgery; age≥60 years; age \<60 years, menopause for at least 12 months (not because of chemotherapy, tamoxifen, toremifene or ovarian suppression) and follicle stimulating hormone (FSH) and estrogen levels are in the postmenopausal range.

2. HER2-negative is defined as: standard immunohistochemistry (IHC) detection is 0/1+; ISH detection: the HER2/CEP17 ratio is less than 2.0 or the HER2 gene copy number is less than 4 (confirmed by the researcher at the test center).
5\) According to the RECIST1.1 standard, patients must have: a) measurable lesions; b) unmeasurable osteolytic or mixed (osteolytic + osteogenic) bone lesions in the absence of measurable lesions.
(6a) The following criteria are met: premenopausal patients are allowed to receive ≤1 line of chemotherapy for recurrent metastatic disease, and postmenopausal patients are not allowed to receive any chemotherapy for recurrent metastatic disease.
(6b) The following criteria are met: ≤1 line of chemotherapy for recurrent metastatic disease is allowed.
7\) The patient is receiving any of the following treatment regimens, the first dose is administered within 2 months prior to enrollment, and the first efficacy assessment has not been performed: a) Palbociclib in combination with Fulvestrant; b) Fulvestrant.
