Inclusion Criteria Group A: * Patients with histological diagnosis of advanced prostate cancer (defined as the presence of metastatic disease, including both metastatic hormone naïve prostate cancer patients and metastatic castration resistant prostate cancer patients); * Patients who started ADT or ADT plus AR inhibitor therapy (Enzalutamide, Darolutamide or Apalutamide or Abiraterone) in a standard therapy. * Have accessible metastatic and/or primitive disease to perform a biopsy safely during hormonal therapy (ADT or ADT plus AR inhibitor therapy) and before hormonal therapy (alternatively, as a basal biopsy could be used archival FFPE or frozen tumor material left over from surgical procedures or previous biopsies, if available) * Written acceptance of informed consent to be included in the present study. * Aged 18 or over. Inclusion Criteria Group B: * Patients due for prostate biopsy to confirm the diagnosis of a prostate adenocarcinoma at high risk of metastatic disease. High risk is defined as follows: * PSA \>=20ng/dL with or without imaging suggestive of metastatic prostate cancer OR * PSA \>=10 ng/mL and \<= 20 ng/mL AND \>=33% risk to have a high grade disease on prostate biopsy according to the MSKCC nomogram "Risk of high grade cancer of prostate biopsy" (https://www.mskcc.org/nomograms/prostate/biopsy\_risk\_dynamic). * Written acceptance of informed consent to be included in the present study. * Aged 18 or over
