Abstract
Liver malignancies are among the most prevalent cancers worldwide and can be managed using various therapeutic approaches. However, the available options for treating these malignancies are characterized by several limitations. Histotripsy, which was recently approved by the Food and Drug Administration (FDA), seems to be promising for overcoming these limitations. It is an emerging non-invasive, non-thermal ultrasound technology, which is based on the controllable initiation of cavitation from endogenous nanometer-scale gas pockets within tissues. Numerous preclinical studies as well as three clinical studies highlight this technique as feasible, safe, and effective. Among its advantages are the lack of thermal injury, its non-invasive nature, its immunopreserving and possibly immunostimulating ability, as well as the low number of complications that accompany it. Nonetheless, long-term clinical outcomes are still lacking, and further studies are needed to establish its definitive role in liver cancer treatment. In conclusion, histotripsy shows strong potential to become a transformative tool in liver oncology, but continued clinical evaluation is essential to validate its long-term efficacy and integration into standard care.
