How effective is chemotherapy for leukaemia?

Leukaemia is not one illness, so treatment differs between acute and chronic forms and between cell types. Chemotherapy may be used to achieve remission, maintain control, prepare for a stem-cell transplant, or relieve symptoms. Medicines can act in the blood and bone marrow, where leukaemia cells develop. Response is followed with blood counts, examination, bone-marrow assessment, and tests that look for small amounts of remaining abnormal cells when appropriate. A normal blood count is helpful but may not be the only measure used to decide whether treatment is working.

Follow instructions about medicines, food, hand hygiene, and contact with people who are unwell. Keep all blood-test and review appointments because counts can change quickly. Tell the team about dental problems, new medicines, bleeding, bruising, mouth sores, diarrhoea, or reduced urine. Ask whether you need a thermometer, an emergency contact number, or special instructions for fever. Rest when needed, but gentle movement may help if your team says it is suitable.

Contact the leukaemia team urgently for fever or chills, sudden breathlessness, chest pain, confusion, severe headache, uncontrolled bleeding, black stools, or marked weakness. Seek immediate help for fainting, a seizure, or difficulty breathing. Vomiting that prevents fluids, rapidly increasing bruising, or very little urine also needs prompt medical advice.

Which type and treatment phase of leukaemia do I have, and what response are we aiming for? Which blood or bone-marrow results will show that chemotherapy is working? Could a transplant or another medicine be considered, and which symptoms require emergency help?
