Identification of Predictive Biomarkers

Molecular nuclear imaging in prostate cancer has made significant progress in the last few years. The introduction of tracers that target the prostate-specific membrane antigen (PSMA) has profoundly influenced imaging diagnostics in prostate cancer. In case of relapse after curative treatment (especially after radical prostatectomy), PSMA positron emission tomography (PET) has the ability to detect lesions already at very low prostate-specific antigen (PSA) levels. The improved detection of relapses increases the interest of individualized targeted therapies in patients with prostate cancer recurrence. Thus, this development led to the acceptance of PSMA PET for diagnostics in prostate cancer patients with biochemical relapses in national and international guidelines.
