Summary

This study is for women with triple-negative breast cancer, either early-stage or advanced, who are receiving immunotherapy. Researchers want to see if changes in a simple blood marker called CRP can predict how well the treatment works. The goal is to find a way to personalize therapy and improve outcomes.
