Histotripsy: Recent Advances, Clinical Applications, and Future Prospects

Area of Science:

• Oncology
• Medical Imaging
• Ultrasound Technology

Background:

• Solid tumors represent a significant global health challenge.
• There is a need for advanced image-guided ablation techniques that minimize collateral damage and enhance immune responses.
• Histotripsy, a novel non-invasive ultrasound-based ablative therapy, utilizes focused cavitation to destroy tissue.

Purpose of the Study:

• To review current advancements in histotripsy for oncologic and non-oncologic applications.
• To synthesize the clinical applications, limitations, and future directions of histotripsy.
• To evaluate histotripsy's potential in treating various solid tumors.

Main Methods:

• A comprehensive literature search was performed from database inception to July 2025.
• Keywords included "histotripsy," "mechanical ablation," "ultrasound," and "solid tumors."
• Peer-reviewed preclinical, clinical, and review articles were included, with reference lists examined for additional sources.

Main Results:

• Histotripsy demonstrates potential in treating tumors of the liver, pancreas, kidney, brain, and cardiovascular system.
• The technique offers real-time imaging, precise lesion margins, and minimal damage to surrounding tissues.
• Early clinical trials indicate favorable safety and efficacy, particularly for liver and kidney tumors, with potential immune-stimulating properties.

Conclusions:

• Histotripsy is a promising non-invasive approach for tumor ablation, offering advantages over thermal ablation.
• Limitations such as acoustic aberration and motion challenges require further investigation.
• Continued clinical research and technological development are essential to establish histotripsy's role in cancer care.
