@kaydee26 Most likely your doctor didn’t feel the need to bring up a BMT/SCT vs an ASCT because it wasn’t really relevant to your diagnosis and treatment.
Bone marrow transplant, using donor cells (allogeneic transplant) isn’t generally a first-line treatment option used for Multiple Myeloma ASCT, such as the one you had in 2019, remains a standard disease-control approach. It offers the advantage of being able to use your own cells with less toxicity or issues with graft vs host disease. It’s not meant as a long-term cure but can help hold a patient in remission longer. It’s not unusual for patients with an ASCT for MM to have repeat procedure down the road.
Anyway, you now have gone through the CAR-T therapy instead of a repeat ASCT and doing really well! So that’s fantastic. However, because you are still considered immune compromised, your doctor has you taking an antiviral medication. This may help protect from reactivation of certain viruses that may be dormant in the body such as CMV, HBV, HPV and others.

You mentioned having some lung issues that pre-dating the CAR-T. So I hope you continue improvement in both areas so you can get back to fewer doctor’s appointments. ☺️
