I am sorry that your post hasn’t had any replies as yet. I think this is probably because allogeneic (allo) transplants are carried out fairly infrequently in myeloma and perhaps no one with experience of this has read your post.
My name is Ellen and I am one of the Myeloma Information Specialists at Myeloma UK. I speak to lots of patients and families every day on the Freephone Myeloma Infoline, if it would help to talk to me then please do call the Infoline on 0800 980 3332, I will do my best to answer any questions that you have.
I can also put your husband in touch with another patient who has had an allo transplant on our PEER Network programme, on a one-to-one basis over the phone. I would be very happy to arrange this, if you think it would be suitable, please let me know.
With best wishes
Ellen
