Abstract

Increased understanding of prostate cancer biology has led to new treatment strategies and promising new agents for treating prostate cancer, in particular peptide-based agonists and antagonists. In this review article, new therapy modalities and potential approaches for the treatment of advanced prostate cancer are discussed, including agonists and antagonists of luteinizing hormone-releasing hormone, antagonists of bombesin/gastrin-releasing peptide, and growth hormone-releasing hormone and somatostatin analogues. Though the prognosis of patients with prostate cancer is much improved by some of these treatment approaches, including combination treatment methods, extensive side-effects are still reported. These include sexual dysfunction, functional lesions of the liver and renal system, osteoporosis, anaemia and diarrhoea. Future studies should focus on new treatment agents and treatment approaches that can eliminate side-effects and improve quality of life in patients with prostate cancer on the basis of potent treatment efficacy.
