In an allogeneic transplant the stem cells come from a donor: a brother, sister, parent or registry volunteer.

01Short answer

The donor cells build a new marrow and a new immune system. That immune system can attack remaining leukaemia cells, which is the main benefit. But it can also attack healthy tissues: graft-versus-host disease (GVHD). To prevent it, immune-regulating medicines are taken for months.

02Simple explanation

Topic. allogeneic transplant.

Ask. Your team will explain your own situation.

Write down. Your questions.

Overview. The article “Stem cell transplant”.

03Scientific explanation

GVL: the graft-versus-leukaemia effect lowers relapse risk.

GVHD: can affect the skin, liver, gut and other organs.

09Frequently asked questions

Must the donor be a sibling?

No; a registry donor or a half-matched relative can also be used.

Is this the same for everyone?

No; the plan depends on the type of leukaemia and your situation.
