Thus, in case of good PSA response after salvage treatment, there is no indication for performing PSMA PET/CT (statement 1.4); also, in case of late-stage disease where no further therapies can be initiated or hormone sensitive PCa with favorable PSA response under systemic therapy, there is no role for PSMA PET/CT (statements 1.5 and 1.6). This evidence concerns the gene FOLH1 and posterior cortical atrophy.
