Overview

The primary objective of this study is to explore the efficacy and safety of adaptive therapy in the treatment of post-second-line metastatic breast cancer.

This is a phase II, prospective, single arm clinical trial. The objective of the study is to evaluate the efficacy and safety of adaptive therapy in the treatment of post-second-line advanced breast cancer. The therapy regimen primarily including Gemcitabine, Vinorelbine, or Eribulin, will be selected by the investigator based on current guidelines, available treatments, and an assessment of the patient's clinical status, preferences, and financial situation. This study plans to recruit 10 subjects.
