Standard-risk B-cell acute lymphoblastic leukaemia in children: the decisions you may face
4 treatment settings, 4 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.
Induction (four weeks)
Vincristine, dexamethasone and pegylated asparaginase with intrathecal methotrexate; flow cytometry MRD at day 29 decides the post-induction arm.
A plant-derived chemotherapy from the Madagascar periwinkle that has been in almost every childhood leukaemia and lymphoma regimen since the 1960s.
Dexamethasone is a long-acting glucocorticoid steroid that kills lymphoid cancer cells directly, which is why it sits in nearly every myeloma regimen and in childhood leukaemia and lymphoma protocols. It is also the standard drug for preventing chemotherapy sickness and for brain swelling and spinal cord compression; high blood sugar, insomnia, muscle wasting and infection follow prolonged use.
An enzyme that starves leukaemia cells of an amino acid they cannot make; a mainstay of childhood ALL therapy for 50 years, with new versions solving allergy and supply problems.
The 1948 antifolate that produced the first chemotherapy remissions in childhood leukaemia and the first cure of a solid tumour; still essential in ALL, lymphoma, osteosarcoma and CNS lymphoma.
Flow cytometry MRD counts leukaemia cells in the bone marrow one at a time by their surface proteins, down to one in ten thousand.
- Broadly applicable, fast (same day)
- Works without a molecular marker
No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.
- Fatal if given intrathecally: label all syringes.
- High-dose methotrexate requires normal renal function, hydration, urine alkalinisation and leucovorin rescue with level monitoring.
- Operator and lab dependent
- Sensitivity below molecular methods; immunophenotype shift after therapy
- Between Vincristine, Dexamethasone, Asparaginase (pegaspargase, calaspargase pegol, Erwinia asparaginase) and the other options, which do you recommend for me, and what about my case would make you choose differently?Why: Guidelines list several reasonable options; the choice turns on details of your tumour, your health and your priorities.
- What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?Why: The aim shapes how much side effect and disruption is worth accepting.
- What happens if I delay, or decline this step for now? Is the decision reversible?Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
- Does your recommendation follow the current guideline (NCI PDQ: Childhood Acute Lymphoblastic Leukemia Treatment (health professional version)), and if it departs from it, why?Why: Departures from guidelines are sometimes right for an individual; they should be explained.
- For my situation (induction (four weeks)), which of the standard options do you recommend and why?Why: Guideline options include: Vincristine, dexamethasone and pegylated asparaginase with intrathecal methotrexate; flow cytometry MRD at day 29 decides the post-induction arm.
- Am I a candidate for Vincristine, Dexamethasone, Asparaginase (pegaspargase, calaspargase pegol, Erwinia asparaginase) or related drugs, and what side effects should I expect?Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Consolidation and interim maintenance
Cyclophosphamide, cytarabine and mercaptopurine, then escalating methotrexate; two cycles of blinatumomab added for standard-risk average and high disease (AALL1731).
Cyclophosphamide is an alkylating chemotherapy that damages DNA in dividing cells. It is part of CHOP for lymphoma, AC for breast cancer and VAC for childhood sarcomas, clears lymphocytes before CAR-T and prevents graft-versus-host disease after transplant; bladder bleeding, infertility and secondary leukaemia are its harms.
Cytarabine is the core chemotherapy for acute myeloid leukaemia, given with an anthracycline as the classic 7+3 induction and at high doses for consolidation; it is also injected into the spinal fluid to treat or prevent leukaemia in the brain.
Mercaptopurine is a daily tablet, or a liquid for children, that keeps acute lymphoblastic leukaemia in remission during the long maintenance phase of treatment.
The 1948 antifolate that produced the first chemotherapy remissions in childhood leukaemia and the first cure of a solid tumour; still essential in ALL, lymphoma, osteosarcoma and CNS lymphoma.
Blinatumomab was the first T-cell engager (2014), and is now given to children and adults with leukaemia even when in remission, because it improves survival.

Delayed intensification and maintenance
One delayed intensification block with vincristine, dexamethasone, doxorubicin, asparaginase, cyclophosphamide, cytarabine and thioguanine; then daily mercaptopurine, weekly methotrexate and vincristine-steroid pulses to two years or more.
A plant-derived chemotherapy from the Madagascar periwinkle that has been in almost every childhood leukaemia and lymphoma regimen since the 1960s.
Dexamethasone is a long-acting glucocorticoid steroid that kills lymphoid cancer cells directly, which is why it sits in nearly every myeloma regimen and in childhood leukaemia and lymphoma protocols. It is also the standard drug for preventing chemotherapy sickness and for brain swelling and spinal cord compression; high blood sugar, insomnia, muscle wasting and infection follow prolonged use.
The red chemotherapy drug from a soil bacterium that is still the backbone of treatment for sarcoma, lymphoma and breast cancer, limited by cumulative heart damage.
Cyclophosphamide is an alkylating chemotherapy that damages DNA in dividing cells. It is part of CHOP for lymphoma, AC for breast cancer and VAC for childhood sarcomas, clears lymphocytes before CAR-T and prevents graft-versus-host disease after transplant; bladder bleeding, infertility and secondary leukaemia are its harms.
Thioguanine (Tabloid) is an oral chemotherapy tablet used in some regimens to induce and consolidate remission in acute myeloid leukaemia; long-term use is avoided because it damages the liver.
Mercaptopurine is a daily tablet, or a liquid for children, that keeps acute lymphoblastic leukaemia in remission during the long maintenance phase of treatment.

Relapse
Reinduction chemotherapy with blinatumomab for high- and intermediate-risk relapse; tisagenlecleucel or inotuzumab ozogamicin for later relapse (see the relapsed ALL page).
Blinatumomab was the first T-cell engager (2014), and is now given to children and adults with leukaemia even when in remission, because it improves survival.
Tisagenlecleucel was the first CAR-T therapy ever approved (2017), for children and young adults whose leukaemia had come back after everything else.
Inotuzumab ozogamicin is an antibody carrying a DNA-cutting toxin to CD22 on leukaemia cells. It gets far more relapsed ALL patients into remission than chemotherapy and bridges them to transplant.
