Burning Questions and Controversies in the Management of Advanced Prostate Cancer Patients – Summary
Scott B. Sellinger, MD, President of Advanced Urology Institute and a Partner at Southeastern Urological Center in Tallahassee, Florida, breaks down treatment groups for advanced prostate cancer and details therapeutic options for each. He defines non-metastatic castration-sensitive (nmCSPC), metastatic castration-sensitive (mCSPC), non-metastatic castration-resistant (nmCRPC), and metastatic castration-resistant prostate cancer (mCRPC). Noting that each group requires a different treatment strategy, Dr. Sellinger breaks down the treatment options for each. Selection of additional treatments beyond ADT is important for treating prostate cancer, and he reviews the trials for the androgen receptor inhibitors, including enzalutamide, apalutamide, and darolutamide. Next, Dr. Sellinger reviews the FDA approvals and treatment strategy timeline of abiraterone, apalutamide, and enzalutamide. He details a study comparing the clinical efficacy and safety of abiraterone and enzalutamide in metastatic castration resistant prostate cancer, concluding that enzalutamide was more efficacious than abiraterone, but had higher side effects. Next, he discusses the best time to move away from first line androgen pathway inhibitors, and when to switch to another androgen pathway inhibitor or move to a new treatment entirely. He discusses a study in British Columbia on mCRPC patients which found that enzalutamide showed activity as a second line androgen pathway inhibitor. He notes that the CARD trial found that metastatic prostate cancer patients switching from an androgen pathway inhibitor to cabazitaxel was better than abiraterone or enzalutamide. Last, he reviews PARP inhibitors, enzymes which help repair single strand breaks in DNA, for use in advanced prostate cancer. Dr. Sellinger concludes that germline and somatic testing are important prior to choosing a treatment, and that urologists should consider PARP inhibitors for any patient who meets the criteria for olaparib or rucaparib.
