Brief Summary

This study is a prospective, open-label, phase II clinical study for patients with HR+/HER2- advanced breast cancer.

Detailed Description

Patients with SNF34subtype of HR+/HER2- advanced breast cancer confirmed by the Department of Pathology and Key Laboratory of Breast Cancer of Fudan University Affiliated Cancer Hospital are planned to be enrolled. The main purpose is to evaluate efficacy of Apatinib in SNF4 subtype of HR

+/HER2- advanced breast cancer and prepare for subsequent randomized controlled phase III clinical studies with larger sample size.
