Background: With advancements in diagnostic techniques, oligometastatic prostate cancer is diagnosed in patients who were, in the past, considered to have localized disease. Moreover, evidence of the effectiveness of treatment intensification for this disease is increasing, focusing on primary tumors as well as metastatic lesions. Thus, we can delay the start of systemic palliative treatment and improve overall survival. Many questions remain unclear, such as the definition of oligometastasis disease, or which patients should be offered aggressive treatment. Data are limited and come from small retrospective studies but show conclusively the benefits of survival in targeted primary prostate and metastatic prostate cancer therapy with surgery or radiotherapy. Often, stereotactic radiotherapy is used in this indication, with minimal side effects. In retrospective studies, 3–5 metastatic lesions were generally accepted for definition of oligometastatic disease, but patient subgroups were heterogeneous. A recent study attempts to better define oligometastatic disease and find out the right degree of intensification of treatment. When and in which patient to use metastasis-targeted therapy and when the standard systemic treatment is already meaningful. It is already clear that selected patients benefit from targeted personalized treatment. Purpose: The purpose of this review is to offer an update of the problem of oligometastatic prostate cancer. The article presents an overview of data from contemporary literature, modern possibilities of diagnostic imaging methods and treatment options of oligometastatic prostate cancer including surgery and radiotherapy.
