Icclearly, this study was meant for people already taking, or expecting to take, CAR-T therapy.
Rather than wait six months and see a progression, they can start a different therapy at 15 days, thanks to the results of a cheap blood test that everyone already gets.
I'm sorry, but you don't know what you are talking about!
A patient does not "take" CAR-T. CAR-T is a medical procedure that includes extracting T cells from the patient, genetically engineering those cells, and reinserting them back into the patient to fight the disease (cancer). The reinsertion takes place in a hospital setting over a short period of time (hours), and the modified T cells then seek out and destroy the cancer cells (usually a blood cancer) over a period of a few days. It is not a simple procedure and is about as modern as medicine can be. It also has possible AEs (adverse effects) that can potentially be lethal.
To equate CAR-T assessment to a blood test is ludicrous.
You should be careful about promoting such crazy notions.
