Role of Focal Therapy with High-Intensity Focused Ultrasound in the Management of Clinically Localized Prostate Cancer

Overtreatment of prostate cancer (PC) remains one of the main burdens in uro-oncology. Focal therapy may be a reasonable alternative with less side effects and morbidity. Application of high-intensity focused ultrasound (HIFU) induces immediate and irreversible coagulation.

The treatment leads to consecutive necrosis with sharply delineated margins, making HIFU a promising tool for the focal therapy of localized PC. Unlike radiation, the treatment leaves no collateral damage outside of the heated tissue, allowing repeated use of HIFU, if necessary. In case of non-organ-confined relapse, additional radical salvage therapy can be performed. This review gives an overview of the existing evidence on focal HIFU. Today, 3 HIFU devices are approved for the treatment of localized PC: Sonablate™, Ablatherm™ and the FocalOne™ device. In summary, the first published results of focal HIFU are promising. The quality of life and potency of the patients are well preserved. Therefore, HIFU treatment, and especially focal ablation of tumor foci, seems to be a safe alternative to standard treatment, with low side effects. The oncologic results seem satisfactory but need further follow-up to validate this practice of PC control.
