Background: In metastatic prostate cancer (mPCa), the standard treatment involves systemic treatment including androgen deprivation therapy (ADT), possibly in combination with new drugs called androgen receptor targeting agents (ARTA) or docetaxel. The treatment of the prostate itself in mPCa represents a new paradigm in the so-called oligometastatic prostate cancer (OMPCa), which is considered to be a kind of intermediate stage between localized disease and extensive metastatic disease. Thanks to new diagnostic methods, OMPCa is an increasingly frequently diagnosed stage of mPCa. In addition to improving local control of the disease, aggressive local therapy could lower the need for ADT, or improve survival. Radiotherapy has already demonstrated the oncological benefit of OMPCa in a randomized study and is now part of the guidelines for the treatment of low volume de novo mPCa. Cytoreductive prostatectomy (CP) is still awaiting the results of randomized trials; however, retrospective data already exist to support this treatment modality. Several population-based studies have been published that have demonstrated the benefit of CP. Minor retrospective works have demonstrated the safety of CP in clinical practice. Several prospective randomized trials investigating this treatment modality are currently underway. However, the whole concept of CP in OMPCa is still shrouded in many unresolved issues such as the definition of a suitable patient and the role of another form of local therapy targeted to metastases. Purpose: This article aims to provide an overview of key published or ongoing studies related to CP in relation not only to functional and oncological results but also to the indication criteria and design of individual studies.
