Treatment of prostate cancer using high-intensity focused ultrasound, literature review.

The treatment of prostatecancer has recently been questioned because ofthe adverse effects it causes may out weigh the benefitsin many patients, so, it has increased interest in active surveillance for low-risk diseases and tissue preservation with focal therapy, thereby reducing the burden on medical care and side effects that may occur after radical prostatectomy and radiation therapy. provide updated information on the treatment of prostate cancer with high intensity focused ultrasound therapy. Bibliographic reviewstudy and systematic analysis of 27 scientific articlesfound in the Medline, Scielo and PubMed databases, whose publication dates correspond to the last 5 years.The search criteria used consisted of terms: prostatic neoplasms, ablation techniques, high-intensity focused ultrasound ablation. Focal therapy is a therapeutic option forlow-risk prostate cancer, clinical studies report a 75% cancer-free survival, 99% cancer-specific survival and 96% metastasis-free survival, the prostate antigen is maintained at values lower than 0.1 ng/ml in long-term controls, while the adverse effects of surgery such as incontinence and sexual impotence are rare. HIFU is a less invasive option for the treatment of low-risk prostate cancer, with oncological results similar to radiotherapy and radical prostatectomy.
