Chemotherapy for leukaemia: induction, consolidation and maintenance

Chemotherapy for acute leukaemia is usually given in planned phases rather than as one course. The first phase, called induction, is intensive and aims to clear leukaemia cells from the blood and bone marrow so that normal blood cells can recover. This is followed by consolidation, sometimes called intensification, which aims to destroy leukaemia cells that tests can no longer find but that may still be present. Some types, particularly acute lymphoblastic leukaemia, then have maintenance treatment, which is gentler, often includes tablets taken at home, and continues over a longer period. Chronic leukaemias are usually managed quite differently, often with tablets or careful monitoring, so the phases described here mainly apply to acute leukaemia.

Hospital stays can be long, and families are often surprised by this. Induction usually needs admission for several weeks, because the treatment lowers blood counts sharply and infections, bleeding and low red cells must be treated quickly. Many people need blood and platelet transfusions during this time. Consolidation may involve shorter repeated admissions or day care visits, depending on the type of leukaemia and the plan. Maintenance is mostly given as an outpatient, with regular clinic visits, blood tests and occasional short admissions. Some people go on to have a stem cell transplant, which involves another hospital stay. The whole plan, from induction to the end of maintenance, can stretch over many months or longer.

Which phases you need, how intensive each one is and how long treatment lasts depend on the exact type of leukaemia, genetic and other laboratory findings, how quickly the leukaemia responds, your age and your general health. Children, teenagers and adults are often treated with different plans, even when the type of leukaemia is the same. A haematologist or medical oncologist usually leads treatment, working closely with a team of nurses, laboratory specialists and transfusion staff. This page explains the general pattern of leukaemia chemotherapy, and cannot describe your own plan. Your team will explain what each phase involves for you, what the tests along the way are looking for, and roughly when you can expect to go home.

Induction comes first

An intensive phase aiming to clear leukaemia from the marrow.

Consolidation follows

Further treatment aims to destroy cells that tests cannot find.

Maintenance for some types

Gentler, longer treatment, often tablets taken at home.

It cannot tell you which phases you will need or how long you will stay in hospital. That depends on your type of leukaemia and how it responds.

It also cannot tell you how well treatment will work. Your haematologist can discuss what the tests show.

Different types of leukaemia

Acute myeloid leukaemia and acute lymphoblastic leukaemia are treated with different plans. Some rarer types, such as acute promyelocytic leukaemia, are treated in a very specific way and need urgent care from the start. Knowing your exact type, including laboratory findings on the leukaemia cells, is the first step in understanding your plan.

Chronic leukaemia

Chronic leukaemias usually grow slowly. Some need no treatment at first and are watched with regular blood tests. Others are controlled with targeted tablets taken for a long time. Intensive phased chemotherapy is used much less often, so ask your team how the information on this page applies to a chronic type.

Treatment into the spinal fluid

Some leukaemias can hide in the fluid around the brain and spinal cord. Medicine may be given into this fluid through a lumbar puncture, a needle placed in the lower back. It is done by trained staff with strict safety checks, usually several times over the course of treatment.

Central lines

Because induction involves many medicines, transfusions and blood tests, most people have a central line or a line placed in the arm. It avoids repeated needles. The line needs careful cleaning and dressing, and redness, pain or fever around it should be reported to the team without delay.

Blood and platelet transfusions

Leukaemia and its treatment lower red cells and platelets, so transfusions are common, especially during induction. Families are often asked to arrange donors to replace blood used from the blood bank. The hospital blood bank team can explain how donation works and how to organise replacement donors.

Infection precautions in hospital

While counts are very low, careful handwashing, limiting visitors, avoiding anyone with a cold or fever, and following food safety advice from the team all help reduce infection. Families can help a great deal by following ward rules closely and by bringing only what the nurses say is allowed.

Stem cell transplant

For some people, a stem cell transplant from a donor is recommended after induction or consolidation. Whether it is advised depends on the type of leukaemia, laboratory findings and response. Brothers and sisters are often tested first as possible donors, and the transplant team explains the process in detail.

Tests that check progress

Repeat marrow tests during and after induction show whether leukaemia cells can still be seen. Very sensitive laboratory tests may look for tiny numbers of cells that a microscope cannot find. These results help your team decide whether to continue, intensify or change treatment in the next phase.

Fertility before treatment

Leukaemia chemotherapy can affect fertility. Because induction often has to start urgently, there may be little time, but it is still worth asking whether sperm banking or other options are possible. Your team can advise what is realistic without delaying treatment that cannot safely wait.

Children and adults

Children with acute lymphoblastic leukaemia are usually treated with long plans that include a lengthy maintenance phase. Adults may have different plans, and older adults may be offered less intensive treatment if they are not fit for intensive courses. Each plan is matched to the person, not only to the diagnosis.

Staying near the hospital

Long admissions and frequent visits afterwards place heavy demands on families, especially those travelling from outside Hyderabad. Planning who will stay with the patient, where family members will sleep and how costs will be met helps. Ask the team about attendant passes, lodging options and financial counselling.

The emotional strain

A sudden leukaemia diagnosis followed by weeks in hospital can be frightening and exhausting for patients and families. Low mood, anxiety and boredom are common. Counsellors, support groups and simple routines such as daily calls with family can help people cope during long hospital stays.

What to do next

Ask your team to explain your exact type of leukaemia, which phases are planned, how long you are likely to stay in hospital, how infections will be handled, and who to call day or night once you go home.
