Biomarkers for characterization and therapeutic orientation in castration-resistant prostate cancer.

Whole exome sequencing studies haverevealed the molecular landscape of metastatic CastrateResistant Prostate Cancer (mCRPC) providingnew information about prognostic and predictive factorsof response to therapies. These studies highlightedpotentially actionable targets leading to the beginingof the biomarker-driven era in prostate cancer.Alterations in androgen receptor (AR), DNA repair genes,PI3K-AKT-MTOR pathway or in genes involved incell cycle are frequently observed in mCRPC patientsand may be relevant in the resistance induced mechanismto approve therapy in this setting.

Pathological findings in very low risk prostate cancer in surgical specimens.

Perform a detailed anatomopathological analysis of consecutive surgical specimens in men with clinically very low risk prostate cancer according to National Comprehensive Cancer Network (NCCN) criteria.MATERIALS AND METHODS: The study included 799 prostate cancer patients who under went radical prostatectomy between January 2005 and December 2013. We identified 81 consecutive patients with clinically very low risk prostate cancer.
