Patients with low-risk prostate cancer (PCa) face the difficult decision between a potential overtreatment by one of the standard therapies and active surveillance (AS) with the potential insecurity regarding cancer control. A focal therapy (FT) implies a treatment of the tumor within the prostate only. This review evaluates the current literature and expert opinion of different therapies suited for FT as well as concepts for prostate imaging, biopsy and histopathological evaluation. Currently there is a lack of multicenter, randomized, prospective data on the effectiveness of FT. Nonetheless, the published data indicate a sufficient tumor control with a favorable side effect profile. There are still flaws in the diagnostics with regard to tumor detection and histological evaluation. Multicenter studies are currently recruiting worldwide which will provide new data with a higher level of evidence. At present, the effectiveness of FT should not be compared directly to standard radical therapies and FT should only be performed within studies. In cases of cancer progression after FT a salvage treatment should still be possible.
