Hi Jane/Bear.
We have our final consultation on Wednesday so will ask then if there are any options.
I know that bone marrow biopsy/flow testing is done from time to time to give MRD status in the UK, but not to a high level. i.e the range of MRD negativity can be 1 in 10,000 cells accuracy all the way to 1 in 1,000,000 cells.
If you can get MRD negative at 1 in 1,000,000 then its the most accurate measure we have of long term remission. But NHS testing in the UK doesn’t reach this accuracy. In the US they even use it to see if patients need SCT, because the pre SCT depth of response could be at a level where it wouldn’t improve anything further anyway.
I think with dads light chain ratio still outside range, and him being 68, it probably makes sense for us to go ahead with SCT regardless. But for future monitoring, I really want to see if we can get it done.
Will update if I find anything out.
