The Role of Next-Generation Sequencing in Castration-Resistant Prostate Cancer Treatment.

ABSTRACT: Molecular biomarkers play little role in the current treatment of metastatic castration-resistant prostate cancer (CRPC). The advent of next-generation sequencing (NGS) has enabled the comprehensive molecular characterization of the genomic and transcriptomic landscape of both untreated primary prostate cancer and CRPC. Recent studies demonstrating the feasibility of interinstitution studies obtaining and NGS profiling of metastatic biopsies, targeted NGS approaches applicable to routine formalin-fixed, paraffin-embedded specimens, and NGS approaches applicable to circulating DNA and circulating tumor cells portend near-term adoption of NGS approaches in the management and treatment of CRPC. Important considerations in the clinical implementation of NGS include interpatient and intrapatient heterogeneity, disease progression to neuroendocrine/small cell prostate carcinoma, and incorporation into clinical trial design to demonstrate clinical utility. We review the recent progress in NGS-based characterization of CRPC to understand disease biology and inform on barriers to widespread clinical adoption.

Project description:BackgroundNonmetastatic castration-resistant prostate cancer (nmCRPC) is defined as a rising prostate-specific antigen concentration, despite castrate levels of testosterone with ongoing androgen-deprivation therapy or orchiectomy, and no detectable metastases by conventional imaging. Patients with nmCRPC progress to metastatic disease and are at risk of developing cancer-related symptoms and morbidity, eventually dying of their disease. While patients with nmCRPC are generally asymptomatic from their disease, they are often older and have chronic comorbidities that require long-term concomitant medication. Therefore, careful consideration of the benefit-risk profile of potential treatments is required.MethodsIn this review, we will discuss the rationale for early treatment of patients with nmCRPC to delay metastatic progression and prolong survival, as well as the factors influencing this treatment decision. We will focus on oral pharmacotherapy with the second-generation androgen receptor inhibitors, apalutamide, enzalutamide, and darolutamide, and the importance of balancing the clinical benefit they offer with potential adverse events and the consequential impact on quality of life, physical capacity, and cognitive function.Results and conclusionsWhile the definition of nmCRPC is well established, the advent of next-generation imaging techniques capable of detecting hitherto undetectable oligometastatic disease in patients with nmCRPC has fostered debate on the criteria that inform the management of these patients. However, despite these developments, published consensus statements have maintained that the absence of metastases on conventional imaging suffices to guide such therapeutic decisions. In addition, the prolonged metastasis-free survival and recently reported positive overall survival outcomes of the three second-generation androgen receptor inhibitors have provided further evidence for the early use of these agents in patients with nmCRPC in order to delay metastases and prolong survival. Here, we discuss the benefit-risk profiles of apalutamide, enzalutamide, and darolutamide based on the data available from their pivotal clinical trials in patients with nmCRPC.
