Inprove QOL
decrease transfusions
60% of pts respond
SE: pain at inj site, thrombosis, HTN
Dose for ACD
Procrit 40,000units SC q week or Aranesp 200mcg SC q2weeks
Should get 0.5-1.0g/dL increase Hb in 4 weeks
Increase dose if no response
D/C use if no response with inc doses in 4 weeks
transfuse if Hb <8g/dL
EPO Therapy tests
H/H
Iron studies
Folate
B12 def

Treat with iron supplementation during tx if iron def or not responding
Over responders to EPO therapy
Stop once Hb >12g/dL
Hold until Hb drops below 11g/dL
restart EPO at reduced dose or delayed interval
If Hb rise too quickly >2g in 4 weeks--> reduce
Hb >13g/dL can increase the risk of thrombosis
Some evidence that maintaining Hb>12g/dL can decrease survival
