Histotripsy experiences (liver metastases)

I am getting my dad into NYU Langone to see if he would be a candidate for histotripsy. It uses ultrasound technology to destroy cancer cells and is now FDA approved for the liver only. I’ve written in before but a quick recap: my dad has stage IV with liver mets, tumor on pancreatic head. 4 rounds of folfirenox proved unsuccessful and he has chosen not to proceed with more chemo using gemcitabine.

Any experiences undergoing histotripsy? Positive or negative, please share! Here is link for more info https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9404673/
