Usefulness of Tumor Heterogeneity Assessment in Patients With MCRPC Undergoing Radioligand Therapy With 177LU-PSMA-617 Using Serial 18F-DCFPYL, 18F-FDG and 18F-Fluciclovine PET/CT Predicting Clinical Outcome

Description:

The imaging analysis will consist in obtaining quantitative measurements of lesion uptake on the pre- and post-LuPSMA RLT (lesion and whole-body SUVmax, SUVmean and tumor volume) at each time point on all PET/CT scans. PET metrics at the lesion- and whole-body level will be compared among different PET radiopharmaceuticals at the same time point, and changes over time will be assessed.
