Ultrassom focalizado de alta frequência: um tratamento não invasivo para o câncer de próstata: revisão integrativa da literatura

Abstract

Introduction: abdomen. The human body is made up of cells that grow, divide, and die. In specific cases some cells can grow rapidly and deregulate, forming a tumor. Prostate cancer (PC) is the most common malignant tumor in men in the world. Treatments for prostate cancer accompany some side effects like, impotence, urinary incontinence, infertility among others. Objectives: To know the alternatives for the treatment of prostate cancer as well as the production of knowledge about focused high frequency ultrasound and to identify the main forms of treatment for prostate cancer. Methodology: This is an integrative review to review the scientific basis of high frequency focused ultrasound (UFAF) using articles in English and Portuguese from 1973 to present, thus showing its historical evolution. The databases used were: Scielo, Bireme, Pubmed and Mendeley. We searched publications containing any combination of UFAF and CP terms. The abstracts resulting from this search were reviewed for relevance to the clinical outcomes of the procedure. Results: New therapeutic methods have emerged in recent years, moving the whole scenario to more "focused" or "targeted" treatment alternatives. Small percentages of side effects have been observed as well as a small recurrence rate of CP with treatment of UFAF. Conclusion: High frequency focused ultrasound treatment can be considered as an alternative noninvasive therapeutic modality for patients with localized prostate cancer.However, the efficacy and safety of UFAF should be evaluated and tested for better or indication.Future advances in technology and safety will undoubtedly expand the role of the UFAF as more patient surveys are published with long-term follow-up.
