The Role of Therapeutic Layering in Optimizing Treatment for Patients With Castration-resistant Prostate Cancer (Prostate Cancer Radiographic Assessments for Detection of Advanced Recurrence II).

OBJECTIVE: To offer recommendations on identification of disease progression, treatment management strategies, and suggestions on timing of initiating and discontinuing specific castration-resistant prostate cancer (CRPC) treatments.

MATERIALS AND METHODS: The Prostate Cancer Radiographic Assessments for Detection of Advanced Recurrence II Working Group convened to provide guidance on sequencing, combination, or layering of approved treatments for metastatic CRPC based on available data and clinical experience.

RESULTS: A consensus was developed to address important questions on management of patients with metastatic CRPC.

CONCLUSION: In the absence of large-scale clinical trials, the Working Group recommends that patients may best be managed with a layered approach of approved therapies with unique or complimentary mechanisms of action.
