Summary

This study tests a more personalized chemotherapy plan for women with early-stage triple-negative breast cancer. The treatment is adjusted based on immune system activity in the tumor and imaging results. The goal is to see if a lighter chemo can still be effective, reducing side effects while keeping cancer from returning.
