Anyone have a normal bone marrow post transplant (both morphology and flow) and normal light chains along with a persistent serum M spike (in my case unquantified due to migration to the beta region) and positive immunofixation (IFE)? This leaves me at VGPR despite negative marrow results. My questions: what happened in the long run; was your doctor dismissive, or not, of the persistent M spike and IFE results?
