Within this project, validation of liquid biopsy assays for early detection of prostate cancer patients is the primary goal.\n\nIn order to determine CTC numbers, 21 ml of blood will be subjected to either CTC-Capture, and 28 ml for the EPIDROP analysis according to standard protocol (For analysis of circulating blood products plasma, analysis of tumor specific mutations or promotor methylation, analysis of extracellular vesicles and microRNA).

Further subset analysis with special emphasis on the identification of high risk PCa patients with aggressive tumours as defined by a Gleason score (\"gold standard\") of 8 or higher (ISUP 4 and higher), will be performed.
