Real-world Studies of CDK4/6 Inhibitors

Overview

A single-center, real-world study evaluated the clinical outcomes and safety of CDK4/6 inhibitors combined with endocrine therapy in HR+/HER2- advanced breast cancer, and conducted a summary analysis of the clinical treatment options after the progression of CDK4/6 inhibitors.

This study aims to collect clinical data and case information from real-world clinical practice of patients with HR+/HER2- advanced breast cancer treated with CDK4/6 inhibitors combined with endocrine therapy. The main research objectives include: 1. To evaluate the differences in efficacy among different CDK4/6 inhibitors combination regimens in advanced patients; 2. To investigate the subsequent treatment options chosen by patients in the real world after progression on CDK4/6 inhibitors, with the aim of constructing a predictive model for the response to subsequent treatments, thereby providing support for clinical decision-making for both doctors and patients in such situations. The secondary objectives include: 1. To truly reflect the differences in adverse reactions of different CDK4/6 inhibitors in the Chinese population through the collection of laboratory and imaging results; 2. To collect tumor samples or peripheral blood samples from some patients for genomic and transcriptomic analyses, in preparation for translational research on the mechanism of CDK4/6 inhibitors resistance.
