Summary

This is a prospective, single-center, randomize-controlled study. The purpose of this study is to evaluate the efficacy of neoadjuvant CDK4/6 inhibitors in patients with high-risk EPclin multigene risk analysis and non-response to Ki-67 2W, and to explore predictive biomarkers for sensitivity to CDK4/6 inhibitor therapy.
