When is targeted therapy recommended for leukaemia?

Leukaemia includes different diseases, and the relevant target can vary by subtype. Blood tests, examination of blood cells, and sometimes bone marrow testing help the haematology team identify the subtype and its molecular features. A targeted medicine may be used as the main treatment, alongside other treatment, or when the disease returns. The choice depends on the target, disease activity, previous treatment, and your general health. Targeted treatment can affect healthy cells as well, so monitoring is part of care.

Ask which leukaemia subtype and molecular marker were found, and whether the proposed medicine is intended to control active disease or reduce the chance of it returning. Discuss how it will be taken, which blood tests are needed, and whether other medicines or foods could interfere. Keep a current list of medicines and report new symptoms promptly.

Contact your oncology team promptly for fever, chills, unusual bleeding, marked weakness, new breathlessness, or signs of infection. Seek urgent help for severe breathing difficulty, confusion, fainting, or bleeding that does not stop. Do not pause or restart a targeted medicine without advice, because the timing can affect treatment planning.

Which target was found, and how certain is the test result? What benefit is expected from this medicine? How will response and side effects be monitored? What should I do if I miss a dose?
