Does allogeneic stem cell transplant treat acute myeloid leukaemia?

Allogeneic means the stem cells come from a matched donor. Before the cells are infused, conditioning treatment is used to suppress the recipient's bone marrow and immune system and to treat remaining leukaemia. The donor cells then settle in the marrow and begin producing new blood cells.

Donor immune cells can also recognise and attack residual leukaemia cells, an effect that contributes to treatment. The same immune activity can damage healthy tissues, called graft-versus-host disease. Infection, organ effects and delayed blood-count recovery are other major concerns, so transplant requires specialist monitoring.

A transplant is not used for every person with acute myeloid leukaemia. The team weighs the leukaemia's genetic and response features, likelihood of returning, donor availability, age, organ function, other medical conditions and personal priorities. It is often considered once the leukaemia has responded to initial treatment, although the sequence varies.

Preparation may include donor matching, heart and lung checks, infection screening, dental assessment and a review of medicines. Arrange a caregiver and reliable transport, and clarify where you must stay after discharge. Take preventive medicines exactly as prescribed and follow guidance on food safety, visitors and infection exposure.

Contact the transplant team immediately for fever, shaking chills, breathing trouble, a new widespread rash, persistent vomiting or diarrhoea, yellowing of the skin or eyes, unusual bleeding, confusion, or being unable to take medicines. These signs may reflect infection, graft-versus-host disease or another treatment complication that needs rapid assessment. Use the team's emergency route at any hour.

Ask why transplant is recommended at this point, how the donor was selected, which conditioning approach is planned, how graft-versus-host disease will be prevented, which vaccinations may need repeating, and what support is available for fertility, nutrition and emotional wellbeing.
