Oligometastatic prostate cancer has been proposed as an intermediate stage between localized and extensively disseminated disease. Oligometastatic disease is being diagnosed more frequently due to the advances in imaging tests. Nevertheless, there is no consensus definition yet of oligometastatic prostate cancer. The importance of this entity is that several studies have pointed out that local and metastasis directed treatment may improve survival in selected patients. However, we need the results of well controlled prospective randomized clinical trials to help a better understanding and management of oligometastatic prostate cancer.
