Introduction:
Active surveillance (AS) is an established approach in the management of low-risk, localized prostate cancer. While the use of AS to manage intermediate-risk (IR) disease has gradually increased over time, there remains uncertainty with regards to its safety, with only a minority of IR patients currently being managed with this approach.
Materials And Methods:
We conducted a narrative review based on an analysis of the literature focusing on articles describing AS for IR prostate cancer. We focus on the uncertainty surrounding AS in IR disease by discussing variations in the definitions and guideline recommendations associated with IR disease, and describing the limitations of the evidence from observational studies and randomized trials.
Conclusion:
The safety of AS for IR disease remains unknown, given the lack of randomized trials and the limitations of the current observational studies. Further research is needed to identify select patients with IR prostate cancer that can be managed safely with AS.
