Efficacy and Safety of Dalpiciclib in Hormone Receptor-positive Advanced Breast Cancer

Recruiting now

Conditions studied: Breast Cancer

In brief

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.
