The FDA has approved a technique using sound waves against liver tumors, according to the University of Michigan, where it was developed.
The technique -- called histotripsy -- could be an alternative to surgery, radiation and chemotherapy, which often have side effects, the university said in a“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,” the release said.
Histotripsy is easier to control to make sure it hits the tumor instead of healthy tissues, unlike radiation, which affects everything in its path. “Histotripsy is an exciting new technology that, although it is in early stages of clinical use, may provide a noninvasive treatment option for patients with liver cancer. Hopefully it can be combined with systemic therapies for a synergistic therapeutic effect,” said Mishal Mendiratta-Lala, MD, professor of radiology with Michigan Medicine and principal investigator on the trial at the university.
