Has anyone tried cryoablation for leiomyosarcoma? Need experiences

I also have been fighting Leiomyosarcoma for 5 + years. It started in my upper right thigh. Had 25 sessions of radiation followed by surgery at Mayo Hospital in Jacksonville, FL. The tumor had wrapped itself around my femoral artery i had 0 margin after surgery. Then it began to spread into my back, close to liver and into my spine and my lung and on the left side of my chest above my lungs I am now talking to Moffitt cancer center in Tampa FL. Yesterday my family I had a zoom call with the cryo radiation Dr's. They presented to us the Cryoablation process. Has anyone had any experiences with this process. The use gasses to freeze the tumor. I have to do some digging to see if my insurance will pay for this procedure. I have questioned them on my tumors on my back also. I am in severe pain, they are pushing against my sciatica. They are going to look into it. Dr. Klein is the dr we spoke to. Any information would be helpful. I am currently on chemo every 3 weeks
