 All FAB subtypes except M3 are usually given induction chemotherapy with cytarabine ( ara @-@ C ) and an anthracycline ( most often <unk> ) . This induction chemotherapy regimen is known as " 7 + 3 " ( or " 3 + 7 " ) , because the cytarabine is given as a continuous IV infusion for seven consecutive days while the anthracycline is given for three consecutive days as an IV push . Up to 70 % of people with AML will achieve a remission with this protocol . Other alternative induction <unk> , including high @-@ dose cytarabine alone , <unk> @-@ like <unk> or <unk> agents , may also be used . Because of the toxic effects of therapy , including <unk> and an increased risk of infection , induction chemotherapy may not be offered to the very elderly , and the options may include less intense chemotherapy or <unk> care .
