Trial Description Title Prostagen Study - Investigation of polymorphisms in genes of the fatty acid metabolism in relation to the evolvement and further development of prostate cancer Trial Acronym [---]* URL of the trial [---]* Brief Summary in Lay Language The aim of this study is to develop a genetic test able to predict the individual course of disease (aggressiveness) in patients with prostate cancer. An accurate prediction could allow a better decision on the most suitable treatment for the individual patient. It will also seek to clarify if a supplementation with omega-3 fatty acids in form of marine phospholipids (Vitalipin ® capsules) could achieve a reduction of prostate specific antigen (PSA) in the blood. Brief Summary in Scientific Language The primary study objective is to determine polymorphisms (SNPs) in genes of the fatty acid metabolism and its possible correlation with the incidence of prostate cancer, as well as with the severity of the disease. A secondary objective is to examine changes in the fatty acid composition in blood samples after an intake of omega-3 fatty acids in form of phospholipids over a period of three months (as dietary supplementation) and whether these changes depend on the individual SNPs constellation. Based on the results of this research, an improved decision regarding therapy and/or dietary recommendations (in relation to omega-3-fatty acids) the most suitable for each patient, could be created.

Secondary Outcome To assess changes in the fatty acid composition in plasma after the supplementation with the omega-3-preparation and its relation to the found SNP. Phospholipids, lysolipids and their fatty acid composition in plasma at baseline and after three months of omega-3-intake will be analyzed.
