I was infused with CAR-T cells this February past. The final stubborn spot on my duodenum was completely obliterated 30 days later. I spent 2 weeks in our local cancer facility being observed for neurotoxicity and cytokine syndrome either of which never materialized. As a caregiver just be prepared to make trips back and forth to the hospital/care centers and hope for the best. This treatment is really quite magical. I started camping and golfing again in May. Still awaiting the return of my immune system - very small price to pay. I am doing an ivig transfusion today incidently.
