Summary

This study looks back at data from 201 people with triple-negative breast cancer who received chemotherapy or immunotherapy before surgery. The goal is to compare how often the cancer completely disappears after treatment and find out what factors influence success. This is an observational study, not a test of a new drug, so it helps doctors learn which treatments work best for this aggressive cancer.
