【 摘 要 】

Prostate cancer (PC) is one of the most urgent problems of modern urologic oncology in Russia because of a steady rise in morbidity and mortality rates associated with this disease. Radical prostatectomy (RP) and external beam radiotherapy (EBRT) or brachytherapy are mainstay treatments in patients with localized and locally advanced PC. Just the same, the rate of lymphogenic disease progression after radical treatment is as high as 15–40 %. At the same time, a search for a tumor focus leading to an increase in the marker is extremely important. If a local recurrence is detected after previous RP, there may be salvage EBRT. After verifying the relapse after salvage EBRT or brachytherapy, RP may be recommended to patients in the specialized centers having appropriate experience with this type of surgery. In patients with distant metastases, palliative hormonal therapy has been the only conventional method so far. Nonetheless, in a considerable number of patients, a marker recurrence may be associated with the so-called oligometastatic progression of the disease, in which the number of detected metastatic foci is minimal. The clinical introduction of promising and precise diagnostic methods having high sensitivity and specificity even with the minimal levels of prostate-specific antigen, such as magnetic resonance imaging and positron tomography, could substantially increase the number of detectable patients with oligometastases and propose new therapeutic conceptions for the treatment of this contingent of patients. Recently, in the literature there have been increasingly more works suggesting the possibility of using local treatments (surgery or radiotherapy) in patients with oligometastases when the disease progresses after radical treatment. The results of investigations show that a personalized approach and surgical or radiation treatments in selected patients make it possible to increase survival prior to the use of hormonal treatment and, in a number of cases, to completely abandon the latter. The paper gives a review of the literature data dealing with this problem.
