Goal for treating AML in hospital
- wipe out leukemia with induction therapy
- most patients start with 7+3, BM at day 14, 60% patients are free of disease, 40% with residual disease
- start 5+2 if they have residual. Then wait another week and obtain another BM
- after 5+2, 30% patients are free of disease, 10% still has residual disease
- keep patient alive while their immune system is compromised
- this is what the leukemia residents do
- 85% of death are from infection, 10% from bleeding in brain
- recover normal counts
- usually 3 weeks after last week therapy
- 7+3: day 28
- 5+2: day 42
- Platelets come back first, then WBC, then RBC last
- cure person with consolidation
- cure rate only 10% if does not do consolidation
- High dose cytarabine (Hi-DAC): 6 dose, then stop.
- Standard dose cytarabine need transport to carry into cell. Cells become resistant by not have transport protein. High dose passively diffuse across cell membrane so more difficult to develop resistance.
- Side effects: also diffuses into tears and sweats. Eye sx, neurologic sx.
- Conjunctivitis: eye drops
- Cerebellar toxicity: perform finger to nose test daily
- Acral Erythema
- Remission driven by age
- < 60 years old: 95% live
-
60 years old: 90% live
- 80% all ppl go into remission
- cytogenetics and molecular markers affect remission
- poor prognosis:
- p53, flt3, preceding MDS, preceding treatment induced AML
- Try to do 1 dose consolidation and then get to SCT
- Cure rate also driven by age
- < 60 years old: 35-40%
-
60 years old: even less
- relapse: try Hi-Dac then get to SCT
ALL: gentler induction, but much longer maintenance (2-3 yrs) with MTX, vincristine.
