Focal therapy for prostate cancer: current status and future perspectives

Area of Science:

• Urology
• Oncology
• Medical Imaging

Background:

• Focal therapy is an emerging prostate cancer treatment.
• It aims to destroy tumors while preserving surrounding tissue and function.
• It represents a middle approach between active surveillance and radical treatment.

Purpose of the Study:

• To highlight the importance of patient selection in focal therapy for prostate cancer.
• To discuss advancements in imaging and biopsy techniques for tumor localization.
• To identify future challenges and research directions in optimizing focal therapy.

Main Methods:

• Review of current focal therapy technologies (cryoablation, HIFU, etc.).
• Emphasis on advances in multiparametric MRI (mpMRI) for tumor localization.
• Discussion of MR-guided biopsy techniques versus traditional systematic biopsies.

Main Results:

• Improved tumor localization and detection rates with advanced imaging and biopsy techniques.
• Focal therapy aims to maintain disease control while preserving erectile, urinary, and rectal function.
• Patient selection remains a critical factor for focal therapy success.

Conclusions:

• Accurate patient selection is paramount for effective focal therapy in prostate cancer.
• Continued research into molecular, genetic, and imaging markers is needed.
• Future efforts should focus on differentiating aggressive from indolent tumors for optimal treatment stratification.
