RE:Difficult-to-value$-TLT...Excellent points. I'm no health expert, but I'd imagine the patients TLT is currently treating after other treatments did not cure/help, from wildbird1's points 3, 4, and 5, are already immunocompromised because they are exhausted from the side effects of previous treatment regimens. Yet T:T is still getting excellent results. Imagine the results TLT will get when they finally have the chance to be the first line of treatment and can make use of a patient's more robust immune response. Methinks it will improve their percentages significantly.
