Study on Using TROP2-PET and 18F-FDG PET to Predict the Efficacy of Anti TROP2 ADC Treatment in Advanced Breast Cancer

Summary

This study aims to evaluate whether \^68Ga-TROP2 PET/CT, combined with \^18F-FDG PET/CT, can predict the efficacy of anti-TROP2 antibody-drug conjugates in patients with advanced HER2-negative breast cancer. Baseline and dynamic imaging parameters will be used to develop prediction models (primary endpoint: AUC), and their associations with clinical outcomes and tumor TROP2 status will be explored.
