Prostate cancer is one of the most common urological malignancies. Improved diagnostic methods and widespread implementation of mandatory prostate specific antigen (PSA) testing in a number of clinics have led to an increase in the number of timely diagnosed cases of localized and locally advanced prostate cancer, as well as to the expansion of indications for radical therapies. Nevertheless, 30 % to 50 % of patients (depending on their risk) develop biochemical relapse after surgery or

... rapy. Non-metastatic castration-resistant prostate cancer is usually a result of disease progression after radical treatment and long-term androgen-deprivation therapy, which manifests by constant increase in the PSA level along with castrate level of testosterone and no distant metastases according to the results of comprehensive radiological examination. A number of large clinical studies have demonstrated that regular examinations and control of PSA doubling time (main prognostic factor associated with poor disease outcome) are crucial to increase survival and prevent the development of distant metastases.This paper aims to provide an overview of existing literature on the problems associated with diagnosis and treatment of non-metastatic castration-resistant prostate cancer. We have analyzed large randomized studies that demonstrated an increase in the overall survival of patients receiving selective androgen receptor antagonists.
