Resistenzmechanismen unter antihormoneller Therapie des fortgeschrittenen Prostatakarzinoms

With the development of Abiraterone and Enzalutamide new treatment option have become available in addition to Docetaxel for first-line treatment of castration resistant prostate cancer. However, resistance and ultimately failure occurs inevitably with all available treatment options. Moreover, cross-resistance leads to considerably reduced efficacy in second-line treatment. Preclinical data suggest discriminative mechanisms of resistance development for Abiraterone and Enzalutamide. Clinical confirmation of these putative mechanisms for treatment failure might facilitate recommendations for future sequencing of these drugs.
