When is chemotherapy recommended for acute lymphoblastic leukaemia?

Acute lymphoblastic leukaemia can progress quickly, so treatment commonly begins after blood and bone-marrow testing confirms the diagnosis. Therapy may include an initial phase to induce remission, further treatment to remove remaining cells, and maintenance treatment to reduce the chance of return. Medicines may be given through a vein, by mouth or into the fluid around the brain and spinal cord. The plan differs for children and adults and may include targeted treatment or a stem-cell transplant for selected situations.

Ask the haematology team to explain the treatment phases, admission arrangements, fertility preservation and infection precautions. Keep a current list of medicines and tell the team about allergies, vaccinations and other health conditions. Blood tests and examinations are used to track response and to guide transfusions or supportive medicines. Take prescribed medicines exactly as directed and call before taking a new product, including an over-the-counter medicine.

During treatment, contact the team immediately for fever, chills, a new cough, burning when passing urine, uncontrolled vomiting, bleeding, severe headache or confusion. Reduced infection-fighting cells can make an infection urgent even when symptoms seem mild. Go to emergency care for severe breathlessness, heavy bleeding, a seizure or sudden weakness, while also notifying the oncology service.

Which subtype and risk features guide my plan? What happens in each treatment phase? Will I need treatment to protect the brain and spinal cord? How will response be checked? When should I call the team?
