The backbone of therapy is multi-agent chemotherapy with vincristine, corticosteroids and an anthracycline with allogeneic stem cell transplantation for eligible candidates (1):
- chemotherapy consists of
- induction
- consolidation
- long-term maintenance
- maintenance therapy utilizes oral 6-mercaptopurine or methotrexate delivered once weekly or once monthly (2)
- with CNS prophylaxis given at intervals throughout therapy
- elderly patients are often unable to tolerate such regimens and carry a particularly poor prognosis
If the patient has Ph-chromosome positive ALL, the current treatment includes the use of tyrosine kinase inhibitors like imatinib, nilotinib, dasatinib, or ponatinib (2,3)
- have been associated with improved 4-year survival rates of 85% to 90% in Philadelphia chromosome–positive ALL
Children respond well to treatment:
- 95% achieve complete remission
- 50-60% of whom are cured with postremission chemotherapy
Fewer advances have been achieved in adults:
- 80% achieve complete remission
- about 35% achieve long-term disease-free survival
Notes:
- allogenic transplantation has shown clear benefits in the following patients who are at high risk of ALL:
- individuals with Philadelphia chromosome-positive disease
- poor initial response to treatment (4)
- it is also useful in improving the outcome of adults with the t(4;11) subtype of ALL (but the benefits in infants with this genotype is controversial) (4)
