Brief Summary
To explore the efficacy of 68Ga-GZMB PET/CT in assessing the response to neoadjuvant therapy for breast cancer, and to investigate the optimal SUVmax threshold of 68Ga-GZMB PET/CT for predicting pathological complete response (pCR), aiming to provide a new and effective means for accurately and non-invasively evaluating the efficacy of neoadjuvant therapy.
