Intermediate- and long-term oncological outcomes of active surveillance for localized renal masses: a systematic review and quantitative analysis.

Active surveillance is a safe intermediate- and long-term management option for well-selected patients with LRMs, especially those with SRMs. Limited data are available for non-SRMs, but current evidence would support further evaluation of this approach in selected patients. It is not possible to draw definitive conclusions until more high-quality data become available.
