Prostate focal therapy: targeted treatment with hopeful early results but debated long-term proof

Focal therapy uses MRI-identified prostate lesions and energy-based methods (cryotherapy, laser ablation, and high-intensity focused ultrasound) to destroy cancer tissue in a single session, offering quicker recovery and fewer early side effects than surgery or radiation. While some centers report high satisfaction and favorable short- to mid-term outcomes, rigorous randomized trials are lacking and major guidelines label the approach experimental; uptake remains low and coverage by insurance is inconsistent, underscoring ongoing debates about long-term cancer control versus quality of life.

Exploring the Science of High-Speed Laser Ablation.

Researchers at the University of California, Berkeley, have studied the ablation dynamics of copper using gigahertz femtosecond bursts via time-resolved scattering imaging, emission imaging and emission spectroscopy. The combined methods resulted in the fast removal of molten liquid material, while halting material removal after burst irradiation. The researchers obtained direct insights into the dynamics and dominant mechanism of gigahertz ablation with femtosecond pulses. The outcomes provide insights to comprehensively understand ablation mechanisms underlying gigahertz femtosecond bursts that are critical to explore a variety of applications across laser processing, machining, printing and spectroscopic diagnostics.
