High-Intensity Focused Ultrasound for the Treatment of Prostate Cancer: A Review

Area of Science:

• Urologic Oncology
• Medical Physics
• Cancer Therapy

Background:

• Increasing life expectancy and earlier prostate cancer detection necessitate advanced treatments.
• Conventional therapies (surgery, radiotherapy) have limitations, including recurrence risk and morbidity impacting quality of life (QOL).
• There is a need for curative prostate cancer therapies with comparable efficacy and reduced side effects.

Purpose of the Study:

• To evaluate High-Intensity Focused Ultrasound (HIFU) as a noninvasive curative therapy for prostate cancer.
• To explore HIFU's potential to improve cancer control and preserve patient QOL.
• To review the current status and future directions of HIFU in prostate cancer treatment.

Main Methods:

• HIFU utilizes focused ultrasound energy for noninvasive tumor cell necrosis.
• Clinical research initiated in the 1990s, with approximately 65,000 patients treated globally.
• Combination of neoadjuvant transurethral resection of the prostate with HIFU since 2000 to optimize outcomes.

Main Results:

• HIFU demonstrates potential as an effective noninvasive treatment for localized prostate cancer.
• The therapy aims to achieve tumor destruction while minimizing radiation and surgical excision risks.
• Ongoing research suggests improved efficacy and reduced morbidity with technological advancements.

Conclusions:

• High-intensity focused ultrasound (HIFU) is a versatile, noninvasive therapeutic option for prostate cancer.
• HIFU offers a promising alternative to conventional treatments, with potential for better QOL preservation.
• Further advancements in imaging and focal therapy applications are expanding HIFU's role in managing prostate cancer.
