Management of Node-Positive and Oligometastatic Prostate Cancer.

Historically, stage IV prostate cancer was considered incurable. Although node-positive and oligometastatic prostate cancers are both classified as stage IV, these likely represent distinct clinical groups, and some patients may be curable with aggressive multimodality treatments. There is a lack of randomized evidence, but retrospective studies suggest that radical prostatectomy or radiotherapy may improve survival in these patients. This is an area of great current research interest and prospective randomized trials are needed to help define the optimal treatments for these patients.
