Focal therapy for prostate cancer.

Area of Science:

• Oncology
• Urology

Background:

• Traditional treatments for localized prostate cancer, such as radical prostatectomy and radiation therapy, are associated with significant side effects including erectile dysfunction and urinary incontinence.
• Focal therapy has emerged as a minimally invasive treatment option for carefully selected patients with localized low-intermediate risk prostate cancer.

Purpose of the Study:

• To review commonly used focal ablative therapies for prostate cancer.
• To discuss the role of imaging in monitoring focal therapy outcomes.
• To summarize the current oncologic outcomes of focal therapy based on available studies.

Main Methods:

• Review of existing literature on focal ablative therapies for prostate cancer.
• Analysis of studies reporting on imaging modalities for treatment monitoring.
• Synthesis of oncologic outcomes from short and medium-term studies.

Main Results:

• Focal therapy demonstrates acceptable cancer control in the short and medium term.
• Compared to whole gland treatments, focal therapy shows reduced treatment-related morbidity.
• There is a notable lack of long-term studies evaluating focal therapy efficacy.

Conclusions:

• Focal therapy is a viable option for select prostate cancer patients, offering reduced side effects.
• Imaging plays a crucial role in monitoring treatment effectiveness and guiding follow-up.
• Further long-term studies are essential to fully establish the oncologic safety and durability of focal therapy.
