Acute Lymphoblastic Leukemia: Symptoms, Diagnosis, and Treatment
Acute lymphoblastic leukemia (ALL) is an aggressive cancer of blood-forming tissue in which the bone marrow produces too many abnormal lymphoblasts. It is common in childhood but can also occur in adults.
Possible symptoms
- Fatigue or weakness
- Fever or night sweats
- Frequent infections
- Easy bruising or bleeding
- Shortness of breath
- Unexplained weight loss or reduced appetite
- Bone or joint pain
- Swollen lymph nodes
These symptoms are not specific to leukemia, but persistent or concerning symptoms deserve medical evaluation.
How ALL is diagnosed
Diagnosis typically involves blood tests and examination of bone marrow. Additional testing identifies the leukemia subtype and genetic or molecular features that influence prognosis and treatment. Tests may also assess whether the central nervous system or other sites are involved.
Treatment is individualized
ALL treatment is planned by a hematology/oncology team and commonly includes multiple phases, such as remission induction and consolidation or continuation therapy. Central nervous system preventive treatment is also an important part of care.
Treatment options can include
- Combination chemotherapy
- Targeted therapy for specific molecular subtypes
- Immunotherapy in selected patients
- Stem-cell transplantation in selected situations
- Supportive care, including treatment of infection, anemia or low platelets
Radiation therapy is used selectively rather than automatically for everyone with ALL.
Clinical trials
Clinical trials may provide access to newer treatment strategies and also help improve future care. Whether a trial is appropriate depends on age, disease subtype, treatment stage and other clinical factors.
There is no proven lifestyle method to prevent ALL
The cause of ALL is often unknown. Some risk factors are established, but avoiding ordinary foods or taking supplements has not been shown to prevent the disease.
Follow-up matters
After treatment, ongoing follow-up is important for monitoring remission, recurrence and possible late effects of therapy.
