The Kaplan–Meier curves for the progression-free survival rate of metastatic breast cancer patients stratified by the response on 18F-FLT-PET or 18F-FDG-PET after one or two cycles of chemotherapy. The metabolic responders on post-2c 18F-FDG-PET based on PERCIST showed a significantly higher survival rate than metabolic non-responders
