[Pyrosequencing in uro-oncology: applications in prostate cancer]

Changes in the methylation pattern in particular gene promoters as well as genetic sequence mutations play an important role in carcinogenesis. Molecular methods like pyrosequencing provide the specific analysis of these epigenetic and genetic modifications. In this review the relevance of these alterations for prostate cancer and the function of pyrosequencing will be described and explained on the basis of a search of the PubMed literature database. At present, in uro-oncology only a few studies outlining methylation in prostate cancer and pyrosequencing have been published. Nevertheless, it becomes evident that epigenetic mechanisms as well as specific gene sequence alterations have an impact on the carcinogenesis of prostate cancer and knowledge of these factors might open perspectives in diagnostic approaches of the future.
