GzmB-PET/CT to Evaluate Neoadjuvant Therapy Efficacy in Breast Cancer

Clinical Study on the Evaluation of Neoadjuvant Therapy Efficacy in Breast Cancer Using PET/CT With Granzyme B Imaging Probe


Sponsor

Shanghai Jiao Tong University School of Medicine

Enrollment

50 participants

Start Date

Nov 1, 2024

Study Type

OBSERVATIONAL

Conditions

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.
