Does allogeneic stem cell transplant treat chronic myeloid leukaemia?

It replaces the patient's blood-forming cells with healthy stem cells from a donor. The donor cells rebuild blood production, and donor immune cells may also recognise and attack remaining leukaemia cells. Because transplantation can cause serious complications, it is generally considered only after an individual assessment.

For many people with CML, medicines that target the abnormal leukaemia signal are used before a transplant is considered. A transplant may enter the discussion when the disease does not respond adequately, stops responding, progresses, or when suitable medicines cannot be tolerated. The decision depends on the phase of CML, previous treatment response, general health, organ function and whether a well-matched donor is available.

Preparation involves treatment to make room in the bone marrow and suppress the immune system before donor cells are infused. Recovery includes close monitoring while the new cells settle and start producing blood cells. Infection, graft-versus-host disease and effects on organs are among the issues the transplant team plans to prevent, detect and manage.

Keep a current list of CML medicines, doses, previous responses, side effects and other health conditions. The haematology team may arrange blood tests, bone marrow assessment, tissue matching, heart and lung checks, infection screening and a review of medicines. These results help compare the likely benefit of transplantation with its risks for you.

Plan for practical support as well as treatment. Ask who will help with travel, meals and medicines during recovery, and check which vaccinations or infection precautions the transplant unit recommends. Do not stop a CML medicine or change its dose while waiting for a transplant opinion unless your treating team directs you to do so.

During transplant preparation or recovery, contact the transplant team urgently for fever, chills, new breathlessness, chest pain, confusion, uncontrolled vomiting or diarrhoea, unusual bleeding, a rapidly spreading rash, or inability to drink or keep medicines down. Follow the unit's specific temperature threshold and contact instructions, including outside clinic hours.

Call emergency services for severe breathing difficulty, collapse, a seizure or sudden loss of consciousness. If you are unsure whether a new symptom can wait, use the transplant team's urgent contact number because immune suppression can make infections worsen quickly.

Ask why transplantation is being considered now, what your latest CML results show, whether further medicine options are reasonable, how donor matching will work, and what recovery support you will need. Also ask how fertility, vaccinations, work and follow-up may be affected.
