Therapeutic options for first-line metastatic castration-resistant prostate cancer: Suggestions for clinical practise in the CHAARTED and LATITUDE era

Abstract

In few years the scenario of metastatic prostate carcinoma treatment has radically changed due to improved knowledge of those mechanisms responsible of prostatic cancer cells survival and proliferation. Five new therapeutic agents (abiraterone acetate, enzalutamide, cabazitaxel, radium-223, sipuleucel-T), all able to improve overall survival, have been introduced in the management of metastatic castration-resistant prostate cancer. Moreover, recent evidences showed that adding docetaxel chemotherapy or abiraterone acetate to androgen deprivation therapy significantly increases overall survival of de novo castration-sensitive metastatic prostate cancer patients. Due to this rapid therapeutic evolution clinicians face one crucial challenge: the choice of the best treatment sequencing. In particular, there are no prospective data to guide clinical decision in patients with progressive disease after docetaxel or abiraterone acetate treatment for castration sensitive disease. In this review we provide an overview of the therapeutic agents available for both castration-sensitive and castration-resistant prostate cancer. We propose some biological and clinical insights helpful in selecting the most appropriate treatment for patients progressing after metastatic castration-sensitive prostate cancer treatment with docetaxel or abiraterone acetate.
