Histotripsy Shows Early Technical Feasibility, but Robust Oncologic Efficacy Data Remain Absent

Histotripsy is a needle-free, non-thermal focused ultrasound technique for tumor ablation, but a review finds its clinical evidence is limited to early feasibility studies. Robust trials demonstrating oncologic efficacy (such as local tumor progression-free survival) versus esta…

• This is a review (exact design not specified in source) assessing the current evidence base for histotripsy; patient numbers from human series are small.
• The procedure successfully creates an acoustic cavitation bubble cloud to mechanically destroy tissue, avoiding the heat-sink effect that limits radiofrequency/microwave ablation.
• Primary limitation is the lack of comparative data against standard-of-care ablation; current evidence is insufficient to establish oncologic outcomes.
