Efficacy and Safety of Dalpiciclib in Hormone Receptor-positive Advanced Breast Cancer
Study Details
Study Description
Brief Summary
This study is a multi-center, observational, real-world study. We planned to recruit 420 HR+ locally advanced or metastatic breast cancer patients who had received or had not received prior systemic therapy. All patients included in the analysis were receiving or planning to receive dalpiciclib-containing regimens without restrictions, completely following the physician 's clinical choice, to assess the efficacy and safety of dalpiciclib-containing regimens.

Detailed Description
All patients included in the analysis were receiving or were planning to receive dalpiciclib and other standard therapy, with no restrictions on the regimen and full adherence to physician clinical choices. Patients who qualified after completing the screening tests and assessments entered the study treatment period and were treated and visited with a dalpiciclib -containing regimen as specified in the protocol. Patients underwent imaging assessments and safety assessments according to clinical routine during study treatment, with the investigator 's assessment as the final result.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
age ≥ 18 years, postmenopausal or premenopausal female or male patients, female patients must meet one of the following: a) previous bilateral oophorectomy, or age ≥ 60 years; b) age < 60, natural postmenopausal status (defined as spontaneous cessation of regular menstruation for at least 12 consecutive months without other pathological or physiological causes), E2 and FSH at postmenopausal levels; c) premenopausal or perimenopausal female patients can also be enrolled, but must be willing to receive LHRH agonist therapy during the study;
-
pathological examination confirmed HR-positive male/female breast cancer patients, with evidence of focal recurrence or metastasis, not suitable for surgical resection or radiation therapy with the purpose of cure;
-
Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2;
-
Serum pregnancy test must be performed within 28 days before enrollment in women of childbearing age and the result is negative,And male/female patients are willing to use a medically recognized highly effective contraceptive during the study and within 1 year after the last dose of study drug;

Exclusion Criteria:
-
any evidence of serious or uncontrolled systemic disease, including uncontrolled hypertension, active bleeding disorders, active infections, including hepatitis B, C, and human immunodeficiency virus, or severely impaired bone marrow reserve or organ function, including liver and kidney damage, which, in the opinion of the investigator, would greatly alter the balance of wind benefit/risk.
