Acute lymphoblastic leukemia is a cancer of immature lymphoid cells that accumulates in the marrow and can involve the central nervous system.
Quick Answer
Acute lymphoblastic leukemia is a cancer of immature lymphoid cells that accumulates in the marrow and can involve the central nervous system. Dr. Sachita Baniya (NMC 20158, 8+ years of clinical experience in haematology and haemato-oncology) evaluates acute lymphoblastic leukemia (all) at Kathmandu Neurology Clinic & Cognitive Center, 117 Lal Durbar Marg, Kathmandu, Bagmati Province 44600, Nepal — evidence-based, medically reviewed.
ALL is the most common childhood cancer but also affects adults. Immature lymphoblasts crowd the marrow and may spread to lymph nodes, liver, spleen and cerebrospinal fluid. Treatment is prolonged and includes induction, consolidation, CNS prophylaxis and maintenance, with transplant for selected high-risk patients.
Diagnosis uses bone marrow examination with flow cytometry, cytogenetics, FISH and molecular testing. Cerebrospinal fluid examination assesses CNS involvement, and MRD is measured after induction.
Treatment includes induction, consolidation, CNS prophylaxis and maintenance, with tyrosine kinase inhibitors for BCR-ABL1-positive disease. Allogeneic transplant is considered for high-risk or relapsed disease. CAR-T is an option in selected relapsed B-ALL.
Management is individualized and discussed with benefits, limitations, and follow-up.
There is no established primary prevention. Early recognition of symptoms and prompt referral improve the chance of timely diagnosis.
Red flags — seek urgent care
Yes, ALL is the most common childhood cancer, but it also occurs in adults. Adult ALL often requires more intensive support and has a higher risk of relapse, so transplant assessment is more frequently considered.
ALL treatment includes several phases designed to clear leukemia, prevent CNS relapse and eliminate residual disease. Maintenance therapy can continue for months to years, with regular monitoring.
Chemotherapy is delivered into the cerebrospinal fluid, sometimes with systemic drugs that cross into the CNS, to prevent or treat leukemia in the nervous system. It is a standard part of ALL care.
MRD measures residual leukemia cells after treatment. A deeper response is associated with lower relapse risk, and persistent MRD may prompt a change in treatment or consideration of transplant.
CAR-T is used in selected relapsed or refractory B-ALL, particularly in younger patients. Eligibility depends on the disease, antigen expression, prior therapies and access to a cellular therapy centre.
Selected young adults may benefit from pediatric-inspired regimens, but fitness, comorbidity and tolerance must be assessed. The choice is individualised.
Fever of 38°C or higher, chills, breathlessness, cough, sore throat, diarrhoea or line-site redness need urgent review. Infection can progress quickly during neutropenia.
Follow-up includes blood counts, MRD monitoring where relevant, assessment for late effects, vaccination review and psychological support. Survivorship plans are individualised.
Diagnosis, risk stratification and treatment planning for acute and chronic leukemias.
Eligibility assessment, referral coordination and follow-up for CAR-T cell therapy.
Diagnostic bone marrow sampling for cytopenias, suspected blood cancer and treatment monitoring.
Acute myeloid leukemia is a cancer of immature myeloid cells that builds up in the bone marrow and stops normal blood production.
Chronic lymphocytic leukemia is an indolent cancer of mature B lymphocytes that often needs monitoring rather than immediate treatment.
Non-Hodgkin lymphoma is a group of lymphoid cancers that includes indolent and aggressive subtypes.
