The phylogeny of permanent prostate brachytherapy

Area of Science:

• Oncology
• Medical Physics
• Urology

Background:

• Permanent prostate brachytherapy has a history spanning over a century.
• Current transperineal ultrasound-directed techniques have roots in earlier procedures.
• Historical practices may influence contemporary treatment protocols.

Purpose of the Study:

• To review the historical evolution of permanent prostate brachytherapy.
• To assess the influence of earlier techniques on modern transperineal brachytherapy.
• To identify areas for continuous improvement in prostate brachytherapy.

Main Methods:

• A comprehensive literature review was conducted.
• Historical data on prostate brachytherapy procedures were analyzed.
• Current clinical practices were examined in the context of their origins.

Main Results:

• Key aspects of modern brachytherapy, including seed dimensions, prescribed dose, and treatment sequencing, may be suboptimal.
• These features are considered vestigial, potentially not optimized for current technology.
• Modern transperineal permanent prostate implants are safe and effective.

Conclusions:

• The established practices in permanent prostate brachytherapy warrant ongoing critical assessment.
• Continuous re-evaluation and adaptation are necessary to optimize treatment outcomes.
• Further evolution of the transperineal ultrasound-directed technique is recommended.
