Management of Advanced Prostate Cancer in Senior Adults: The New Landscape

The landscape of treatment for advanced prostate cancer is continually evolving as new therapies are developed and guidelines are constantly updated. However, the management of older men with advanced disease is not optimal. Many men are denied chemotherapy based on their chronological age, not their health status. Androgen‐deprivation therapy (ADT) remains the mainstay of first‐line treatment of advanced disease. Once the disease becomes resistant to castration, docetaxel‐based chemotherapy is the regulatory‐approved standard of care, irrespective of age. The place of weekly docetaxel in patients with poor performance status and signs of frailty has to be further evaluated in clinical studies. New treatments are now available, or on the horizon, for disease that progresses during or after docetaxel therapy. Cabazitaxel and abiraterone have been shown to prolong survival, irrespective of age, and are already in clinical use having received regulatory approval. The optimal sequence for these two agents is still unknown, although there is some indication that in patients predicted to be poor responders to abiraterone (high Gleason score, progression during docetaxel therapy, rapid progression to castrate‐resistant prostate cancer with ADT) cabazitaxel should be the preferred choice. Further advances are being investigated, with promising data reported from phase III trials.
