Wie soll die Hormontherapie beim kastrationsresistenten Prostatakarzinom fortgeführt werden?

M. Spahn, M. Krebs

After an average of 18-36 months under androgen suppression therapy by surgical castration, LHRH, and steroidal or non-steroidal antiandrogens, almost all patients with metastatic prostate cancer show PSA progression as a sign of androgen-independent but still androgen-sensitive tumor growth. Our understanding and the treatment of such castration-resistant prostate cancer has changed markedly. The introduction of new drugs like abiraterone and MDV3100 has shown that prostate cancer progression even in the"hormone-refractory" stage is driven by androgen receptor signaling. Based on this information the question of whether androgen deprivation therapy in castration-resistant prostate cancer should be continued or not is still of relevance. This review gives a critical overview of the literature and current guideline recommendations.
