Current capabilities in treatment of non-metastatic castration-resistant prostate cancer: effectiveness, safety, and quality of life of patients taking darolutamide

Prostate cancer is an important disease in current oncological urology. Radical treatment of patients with localized and locally advanced prostate cancer, including surgical and radiological treatments, often does not cure patients from this pathology, especially in the group with high risk of disease progression; the risk of biochemical recurrence in this patient group can be up to 40-60 %. Widespread application of radical treatment allowed to significantly increase survival of patients from this group. However, in case of biochemical recurrence, the majority of patients require longterm androgen-depriving therapy for suppression of natural testosterone level. In some of these patients during longterm castration therapy, non-metastatic castration-resistant prostate cancer develops (CRPC) in the absence of signs of radiological disease progression. Results of large randomized trials show the necessity of stratification of these patients in the group with high risk of progression considering short doubling period of prostate-specific antigen and realization of distant metastases. The main therapy concept for this patient group is use of new-generation inhibitors of androgen signal to increase time to CRPC metastases and overall life expectancy. The article presents results of large trials performed in patients with non-metastatic CRPC and characterizes the role of one of the most effective drugs, darolutamide, used for treatment in this patient cohort.
