The present invention relates to methods and compositions for diagnosing prostate cancer and/or determining whether a prostate cancer patient is at increased risk of suffering a relapse, or a rapid relapse, of his cancer. It is based, at least in part, on the results of a comprehensive genome analysis on 241 prostate cancer samples (104 prostate cancer, 85 matched bloods, 49 matched benign prostate tissues adjacent to cancer, and 3 cell lines) which indicate that (i) genome copy number variation (CNV) occurred in both cancer and non-cancer tissues, and (ii) CNV predicts prostate cancer progression.
