High-dose Cytarabine and Survival in AML

December 16, 2009 updated by: University of Sao Paulo General Hospital

Role of Consolidation With High-dose Cytarabine in Overall Survival of Adults With Acute Myeloid Leukemia

In adults with acute myeloid leukemia, especially those < 60 years of age, high-dose cytarabine consolidation therapy has been shown to influence survival, but the appropriate dose has not been defined.

Detailed Description

Background In adults with acute myeloid leukemia, especially those < 60 years of age, high-dose cytarabine consolidation therapy has been shown to influence survival. However, the appropriate dose has not been defined. We evaluated survival after cytarabine consolidation therapy at three different doses.

Design and Methods We conducted a single-center, retrospective study involving 499 acute myeloid leukemia patients, aged 18-92 years, all evaluated between 1978 and 2007. Of those 499 patients, 400 received curative treatment and 203 received cytarabine consolidation. The latter were divided into three groups: low-dose (receiving < 1.5 g/m2 of i.v. cytarabine, every 12 h, on 3 alternate days, for up to 4 cycles); medium-high-dose (< 45.45 g-the median dose-by the end of the cycles); and very-high-dose (≥ 45.45 g by the end of the cycles).

Results Among the 400 patients receiving curative treatment, five-year survival was 22.8% (91 patients). Cytarabine consolidation dose was an independent determinant of survival (significant differences were found among the groups), whereas age, karyotype, induction protocol, French-American-British classification and etiology were not. In comparison with the very-high-dose group, the risk of death was 3.871 times (95% CI, 1.043 to 14.370 times) higher in the high-dose group (p=0.043) and 9.775 times (95% CI, 2.493 to 38.320 times) higher in the low-dose group (p=0.001), assuming, in both cases, that age, karyotype, French-American-British classification and etiology of acute myeloid leukemia were constant.

Conclusions Consolidation therapy with high-dose cytarabine appears to improve survival in patients with acute myeloid leukemia.
