Pioneered at the University of Michigan, histotripsy offers a promising alternative to cancer treatments such as surgery, radiation and chemotherapy, which often have significant side effects. FDA officials awarded clearance to HistoSonics, a company co-founded in 2009 by U-M engineers and doctors for the use of histotripsy to destroy targeted liver tissue.
A human trial underway since 2021 at the U-M Rogel Cancer Center and other locations has treated patients with primary and metastatic liver tumors via histotripsy, demonstrating the technology’s ability to meet the testing’s primary effectiveness and safety targets.
Histotripsy works by using targeted ultrasound waves to form microbubbles within the tumor. The forces created as those bubbles form and collapse cause the mass to break apart, killing tumor cells and leaving the debris to be cleaned up by the immune system.
What that could mean for patients is treatment without the physical toll of radiation or chemotherapy, fewer concerns with drug compatibility, far shorter recovery times than with surgery and less treatment discomfort.
