Mechanisms of Prostate Cancer Initiation and Progression

Prostate cancer is a major health problem as it continues to be the most frequently diagnosed cancer in men in the Western world While improved early detection significantly decreased mortality, prostate cancer still remains the second leading cause of cancer related death in Western men Understanding the mechanisms of prostate cancer initiation and progression should have a significant Impact on development of novel therapeutic approaches that can help to combat this disease The recent explosion of novel high-throughput genetic technologies together with studies in animal models and human tissues allowed a comprehensive analysis and functional validation of the molecular changes This chapter will summarize and discuss recently identified critical genetic and epigenetic changes that drive prostate cancer initiation and progression These discoveries should help concentrate the efforts of drug development on key pathways and molecules, and finally translate the knowledge that is gained from mechanistic studies Into effective treatments (C) 2010 Elsevier Inc
