Wiping out your immune system and replacing it has something like a 50/50 survival rate even if you use your own cells. It's a hail Mary than usually either kills or cures. I knew a guy with cancer that had this done. He survived the process, but unfortunately the cells they restored him with were not cancer free like they thought. He died anyway. I think increasing the survival rate for these things could be very useful.
