A chromosome abnormality in which all or part of a single chromosome has been lost.


A laboratory procedure to reduce the numbers of specific cell types in bone marrow donated for transplantation, for example removing some types of lymphocytes. This may be to avoid “mismatch” problems (particularly with unrelated donor transplants) or to selectively remove potentially leukaemic cells in an autograft.


We all go through spells of feeling down, but when you’re depressed you feel persistently sad for weeks or months, rather than just a few days.

Some people still think that depression is trivial and not a genuine health condition. They’re wrong. Depression is a real illness with real symptoms, and it’s not a sign of weakness or something you can “snap out of” by “pulling yourself together”. Read more

Donor lymphocyte infusion

If a patient has had an allogeneic stem cell transplant but the original disease returns, they may be given lymphocytes from the donor. This may get rid of the leukaemia cells.
