How effective is chemotherapy for acute lymphoblastic leukaemia?

Treatment usually follows phases that aim to bring the leukaemia into remission, clear hidden disease, and reduce the chance of return. Medicines may be given by mouth, into a vein, or into the fluid around the brain and spinal cord. Blood tests and bone marrow examinations show how the leukaemia is responding. Minimal residual disease testing may detect very small amounts of leukaemia that ordinary tests miss and can guide the intensity of later treatment.

Follow the treatment schedule closely and report medicines, supplements, infections, and vaccination history to the team. Chemotherapy can lower blood counts, so the team may arrange blood tests, transfusions, infection prevention, and medicines for nausea. Ask which symptoms require a same-day call and how to manage mouth soreness, reduced appetite, or fatigue. Do not stop treatment or take new remedies without checking first.

During chemotherapy, seek urgent advice for fever or chills, breathing difficulty, uncontrolled bleeding, severe weakness, confusion, or inability to keep fluids down. A low white-cell count can make infection become serious quickly, so use the emergency contact supplied by your treatment team.

Ask which treatment phase you are entering, how response will be measured, whether minimal residual disease testing is planned, and what would change the treatment plan.
