Molecular classification of prostate adenocarcinoma by the integrated somatic mutation profiles and molecular network

Abstract Prostate cancer is one of the most common cancers in men and a leading cause of cancer death worldwide, displaying a broad range of heterogeneity in terms of clinical and molecular behavior. Increasing evidence suggests that classifying prostate cancers into distinct molecular subtypes is c...
