[Prostate and breast cancer: similarities and differences].

Prostate and breast carcinomas are amongst the most common new diseases in men and women, with steadily rising incidences. In addition to the significant health consequences, both diseases also lead to a significantly reduced quality of life due to their influence on sexual function. The aim of this work is to identify scientific approaches and research priorities that in the future might lead to synergies in both disciplines by specifically considering the similarities and differences between the two diseases. For this purpose, clinically relevant aspects such as risk factors, treatment options, as well as scientific similarities and differences that offer direct joint research approaches in the areas of cultivation and modeling of both tumor entities were analyzed. Through this approach, we were able to demonstrate that due to the comparable biology of the two diseases and the underlying mechanisms, scientific synergies may certainly lead to targeted research. Clinical similarities also indicate that close collaboration between the two disciplines could lead to improved treatment of our patients. Evidence deficiencies in both diseases (e.g. the metastasis mechanisms of both tumor entities) and controversially discussed aspects such as risk factors clearly show that further scientific projects for a more detailed understanding of both diseases are necessary to ensure future success in the treatment of our patients.
