Effect of idarubicin combined with medium-dose arabinoside in intensive chemotherapy on the prognosis of acute myeloid leukemia / 白血病·淋巴瘤

ABSTRACT

Objective To explore the efficacy and feasibility of idarubicin combined with medium-dose arabinoside in intensive chemotherapy for acute myeloid leukemia (AML). Methods Fifty remittent patients with induced chemotherapy who underwent the intensive consolidation therapy with medium-dose arabinoside from January 2010 to January 2015 in hematology department of General Hospital of Beijing Military Area were considered as the treatment group. The single arabinoside (2 g/m 2, 1/12 h, d1-3) treatment for 50 cases in the same period were considered as the control group. Two groups were performed with 6 courses sequential. There were 28 males, 22 females in the treatment group, and average age was 27.6 years (18-52 years), with 3 cases of M 1, 27 cases of M2, 8 cases of M4, 12 cases of M5. In the control group, there were 30 males, 20 females, and average age was 26.8 years (16-50 years), with 2 cases of M1, 30 cases of M2, 8 cases of M4, 10 cases of M5. Then the complications and disease-free survival of two groups were observed respectively. Results Follow-up was done until June 2015. In the treatment group, 1 case died of pulmonary infection, 2 cases died of septic shock and 3 cases died of pulmonary infection, 1 case died of septic shock in the control group. The treatment related mortality of both groups were 6 % (3/50), 8 % (4/50), the related relapse rates were 32 % (16/50), 52 % (26/50), the disease-free survival rates were 62 % (31/50), 40 % (20/50) respectively in two groups. Conclusion Compared with the single arabinoside, the intensive consolidation therapy with medium-dose arabinoside and idarubicin for the treatment of AML has gained lower relapse rate and the related mortality, and the DFS rate has been improved significantly, which need further clinical application.
